Yaa aan jeclayn inay saaxir noqdaan oo ay ku dhawaaqaan dhawr eray si ay u dhacaan waxyaalo sixir ah? Hagaag^(Well) , ma awoodno inaan ku tuso sida loo noqdo saaxir, laakiin waxaan ku tusi karnaa sida loo sameeyo sixir yar oo kumbuyuutar ah.

Haddii aad leedahay kombuyuutar Windows oo uu ku jiro ^(Windows)Windows 7 , waxaad haysataa PowerShell . Sidoo kale, haddii aad leedahay kombuyuutar uu ku jiro Windows 7 , fadlan u cusboonaysii amniga awgeed.

Laakiin maqaalkani maaha mid loogu talagalay dadka Windows -ka oo keliya . Nooca ugu dambeeyay ee PowerShell waa bilaash waxaana lagu rakibi karaa oo lagu isticmaali karaa kombiyuutarada Mac iyo Linux .

Taasi waa muhiim sababtoo ah waxaad ka barato PowerShell waxaa hadda loo isticmaali karaa ku dhawaad ​​​​kombiyuutar kasta. Yaa garanaya? Waxa laga yaabaa in aad xirfaddan gaadhsiiso heerka xiga oo aad ku dhiirato xirfada Tignoolajiyada Macluumaadka^{(Information Technology)} .

Waa maxay PowerShell?

Jawaabta tignoolajiyada sare ee Microsoft ayaa ah in ay tahay, “… qolof amar ah oo loogu talagalay gaar ahaan maamulayaasha nidaamka. †Waxay u egtahay^{(” Sounds)} cabsi. Laakiin maaha Ma ka taxadartaa kumbuyuutarkaaga? Haa, markaa waxaad tahay maamulaha nidaamka ee gurigaaga.

Ma u sheegtaa kombuyuutarkaaga waxa lagu sameeyo gujisyada iyo furayaasha? Haa, markaa ka fikir qolofka taliska inuu yahay daaqad kale oo aad wax ku qorto si aad ugu sheegto kombayutarka waxaad samaynayso. Waad sameyn kartaa tan.

PowerShell waa sida luqadda barnaamijka, laakiin maaha sida qarsoodiga ah sida kuwa ugu badan. Waxay runtii u akhridaa wax badan sida Ingiriisiga^(English) caadiga ah , taas oo ahayd wax Microsoft ku dadaalay si ay u soo qaadaan kuwa aan barnaamijka ahayn.

Waa habka loo qoro dhawr sadar oo amar ah, oo loo yaqaan script, si nidaamka hawlgalka Windows uu u sameeyo wax aad rabto inuu sameeyo. Kadibna, waxaad ku kaydin kartaa khadadkaas faylka oo aad ku socodsiin kartaa gujin ama jadwal u samee inuu si xilliyo ah u shaqeeyo.

Maxaad ku samayn kartaa PowerShell?

Meesha heerka sare ah ee PowerShell waa in aad awooddo in aad si otomaatig ah u samayso hawlaha, markaa uma baahnid in aad wakhtigaaga ku lumiso samaynta waxyaabo aan caadi ahayn oo soo noqnoqda. Xirfadlaha Maamulaha Nidaamyada^{(Systems Administrator)} , taasi waxay noqon kartaa shay sida abuurista isticmaaleyaal cusub, abuurista ereyada sirta ah, una soo dir e-mail faahfaahinta kormeerahooda cusub.

Gacanta lagu sameeyay, oo gujisyo iyo ku qorid, habkaasi waxa uu qaadan karaa 5 daqiiqo ilaa saacad ama ka badan. Qoraalada saxda ah, Maamulaha Nidaamku waxa^{(Systems Administrator)} laga yaabaa inaanu xataa samayn qayb ka mid ah taas.

Laakiin waxaad rabtaa inaad ogaato waxaad ku samayn karto PowerShell guriga. Wax kasta oo aanad jeclayn inaad samayso marar badan. Isticmaal si aad u bannayso meel ka mid ah darawalkaaga adag adiga oo tirtiraya ku meel gaadhka ah iyo faylasha aad u baahnayn.

Bandow saar kombayutarka ubadkaaga. Dib u magacaw^(Rename) ama habee tiro faylal ah. Taasi waa quruxda PowerShell . Ku dhawaad^(Almost) ​​wax kasta oo aad ku samayn karto kumbuyuutarkaaga, waxaad abuuri kartaa qoraalka PowerShell si aad si otomaatig ah ugu socodsiiso guji ama jadwal.

Sideen u Isticmaalaa PowerShell?

Habka ugu fudud ee lagula shaqayn karo PowerShell waa gudaha PowerShell Integrated Scripting Environment (ISE) . Waxaad ka heli kartaa adigoo gujinaya Start oo ku dhejiya powershell ise^{(powershell ise )} ee bar raadinta gudaha Windows 10 . Waa inaad u aragto sida hoos ku cad.

Markii ugu horeysay ee aan isticmaalno, waxaan u wadnaa maamule^{(Administrator)} ahaan . Si tan loo sameeyo, waa inaad marka hore ku leedahay kombayutarkaaga xuquuqda maamulaha. In Menu-kaaga Bilawga^{(Start Menu)} , ku dhufo midigta PowerShell ISE , ka dibna ku dhufo Run as Administrator .

Waxa laga yaabaa inaad hesho Xakamaynta Helitaanka Isticmaalaha^{(User Access Control)} ( UAC ) oo soo booda digniinta ku weydiinaysa haddii aad hubto inaad tan doonayso inaad samayso. Guji Haa^(Yes) .

Hadda waxaad eegaysaa PowerShell IDE . Muraayadda sare ee daaqadda (1) waa muraayadda qoraalka. Tani waa meesha aad ku qori doonto qoraalkaaga. Muraayadda hoose ee daaqada (2) waa aagga console-ka. Markaad tijaabiso qoraalkaaga, waxaad arki doontaa wax soo saarka muraayadan.

Tani sidoo kale waa halka aad ku arki doonto fariimaha khaldan iyo kuwan oo kale kuwaas oo kaa caawin doona inaad hagaajiso oo aad ka dhigto qoraalladaada mid wanaagsan. Muraayadda dhinaca midig ee daaqadda (3) waa amarka add-on. Ka fakar sida qaamuuska dhammaan amarrada PowerShell ee aad diyaar u tahay.^(PowerShell)

PowerShell waxa ay u timi in aanu socodsiin wax qoraal ah oo aan ahayn kuwii horeba uga tirsanaa Windows . Waxaad u baahan doontaa inaad beddesho si aad u socodsiiso qoraalladaada.

Daaqadda qoraalka, koobiy oo dheji waxyaabaha soo socda:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

Set-ExecutionPolicy qaybteeda waxaa loo yaqaan cmdlet ( Commandlet-ka loogu dhawaaqo). Cmdlets waa waxyaabo awood leh. Ka fakar^(Think) iyaga inay yihiin amarro gaagaaban oo aad ku siin karto Windows , Windows -na waxay sameyn doontaa waxyaabo badan oo aad u adag si aad u qanciso amarkaaga.

Tusaale ahaan waxa uu noqon lahaa in ilmahaaga loo sheego inuu nadiifiyo qolkooda. Gaaban^(Short) oo ilaa barta. Haddii ilmahaagu si fiican u yaqaan nadaafadda qolka, markaas way tagi doonaan oo sariirtooda seexan doonaan, dharkooda dambiisha ayay gelin doonaan, oo alaabta ay ku ciyaaraan iyo buugaagtooda kharifi doonaan, oo xataa way faaruqi doonaan dhulka. Waxay fahmeen in cmdlet Clean-Room uu^{(Clean-YourRoom)} ula jeedo waxaas oo dhan.

Xagga sare ee daaqadda, waxaad arki doontaa falaarta cagaaran. Guji^(Click) taas si aad u socodsiiso amarka

Qaybta -ExecutionPolicy waxay u sheegaysaa Set-ExecutionPolicy siyaasadda la dejinayo. Waa halbeeg. Waxaa la leeyahay, “Waxaan rabaa inaad ka shaqeyso tilmaamahan oo aad tan si gaar ah u sameyso. Waxay u sheegaysaa inay isticmaasho siyaasadda gaarka ah ee RemoteSigned .

Siyaasadda RemoteSigned waxay sheegaysaa in PowerShell aanu fulin, ama socon karin, qoraal kasta oo laga soo dejiyo intarneedka^(Internet) ilaa uu saxeexo daabace la aamini karo mooyee.

Dariiqa wareega, waxay u sheegaysaa PowerShell inay fiican tahay in la socodsiiyo qoraal kasta oo gudaha lagu sameeyay, sababtoo ah kuwan uma baahna inuu saxeexo daabace la aamini karo oo fog. Hadda, qoraalkaaga PowerShell wuxuu awood u yeelan doonaa inuu socodsiiyo qoraal kasta oo aad ku qorto kumbuyuutarkaaga.

Aynu eegno qoraalka si aan u tirtirno faylasha ku meel gaadhka ah. Ma ahan mid xoog badan ama si qotodheer ah sida CCleaner , laakiin CCleaner waxay la timaadaa dhibaatooyinkeeda.

Isticmaal PowerShell^{(Use PowerShell)} si aad u abuurto meel bannaan ^{(Create Space)}Hard Drive^{(Your Hard Drive)} - kaaga

Waxaan u kala jebin doonaa qoraalkan, line-line, si aad u aragto sida uu u shaqeeyo. Dhammaadka, qoraalka ayaa si buuxda loo tusi doonaa si aad koobi uga dhigi karto oo aad dhejin karto haddii aad rabto.

$TempFileLocation = "C:\Users\username\Appdata\Local\Temp\*"

Wax kasta oo calaamad dollar ku hor yaal waa magac doorsooma. Ka fakar sida boorsada si aad alaabta qiimaha leh u geliso. Wallet waxa ay ina xasuusinaysaa calaamada dollarka, alaabta qiimaha leh waxay u egtahay doorsooma, markaa waanu xasuusan doonaa taas. Waxaan abuureynaa boorso, ama doorsoomayaal, oo lagu magacaabo $TempFileLocation . Calaamadda siman waxay u sheegaysaa PowerShell waxa lagu dhejiyo doorsoomahaas.

Xaaladdan oo kale, waxaanu gelinaynaa goobta Windows’ ku meel gaadh ah faylal – C:\Users\username\AppData\Local\Temp\* . Waxaan tan u samaynayna laba sababood; Waa goobta had iyo jeer nabdoon in laga tirtiro feylasha, waxaanan u isticmaali doonaa si aan ugu sheegno PowerShell meesha ay tahay inay aado si loo tirtiro faylasha.

Meesha ay ku qoran tahay isticmaaleha goobtaas, ku beddel magacaaga isticmaale. Kaasi waa magaca isticmaale ee aad isticmaalayso si aad u gasho kombayutarkaga. Xiddigga (*) ee ku yaal dhammaadka keeda waa kaarka duurjoogta ah. Waxa ay u taagan tahay waa wax kasta oo ku jira galka Temp , sababtoo ah wax kasta oo ku jira galka Temp waa ku meel gaar waxaana dooneynaa inaan tirtirno.

Xigashooyinka laba-geesoodka ah ee agagaarka goobta ayaa sidoo kale muhiim ah. Taasi waxay u sheegaysaa PowerShell in waxa ku jira uu jiro xadhig. Ka fakar^(Think) xadhig sida xarfo iyo xarfo xarfo ah. Haddii ay ahaan lahayd tirooyin caadi ah, ma aan isticmaalno xigashooyinka.

$TempFile = Get-ChildItem $TempFileLocation -Recurse

Waxaan sameyneynaa doorsoome kale. Markan waxaan isticmaali doonaa amar si aan ula nimaadno wax lagu dhejiyo doorsoomaha $TempFile .

Get-ChildItem 

Wax kale oo aad ka ogaan doonto cmdlets sida Get-ChildItem waa in gebi ahaanba la akhriyi karo. Bal eeg sida erayga ugu horreeya uu fal u yahay? Cmdlets dhamaantood waxay ku bilowdaan kelmado ficil ah, si aad isla markiiba u ogaato waxa ay qabanayso. ChildItem waa laba magac.

Qaybta labaad ee cmdlet waxay had iyo jeer noo sheegi doontaa waxa PowerShell uu ku dabaqi doono ficilka. ChildItem macnaheedu waa dhammaan carruurta goobta waalidka. Tani waxay la mid tahay inaad tidhaahdo soo hel dhammaan faylasha ku jira galka, oo ay ku jiraan faylalka carruurta iyo galku waa waalidka.

Waa maxay cmdlet ka helaysa alaabta ilmaha? Wax kasta oo ku jira doorsoomiyaha $TempFileLocation . PowerShell waxay aadi doontaa meesha aan ku shubnay $ TempFileLocation ka hor oo ay helna dhammaan alaabta ilmaha ee jira. Kadib, waxay gelin doontaa doorsoomaha $TempFile .

Haddaba, maxaa ka jira qaybta soo noqoshada^{(-Recurse )} ? Taasi waa u sheegaysa Get-ChildItem si aad u dhex marto wax kasta oo goobtaas ah. Kaliya ha tagin faylalka isla markiiba gudaha galka waalidka. Haddii ay jiraan galal ku jira galkaas, soo qaado dhammaan carruurtooda, iyo carruurtooda iyo wixii la mid ah. Waanu heli doonaa dhamaantood.

$TempFileCount = ($TempFile).count

Haa, waxaanu abuureynaa doorsoome sadexaad oo loo yaqaan $TempFileCount , waxaanan ku dhejin doonaa lambar doorsoomahaas. Aaway nambarku? Hagaag, ( $TempFile).count ayaa na heli doonta lambarkaas. Waxaad u badan tahay inaad ogaatay in qaybta tirinta ay samaynayso tirinta dhammaan faylasha aan hadda ku kaydinay $ ^(TempFile)TempFile^(.count) .

Maxaynu tan u samaynay? Inta badan sababtoo ah way fiicantahay in la ogaado inta faylal aan faa'iido lahayn ee aan ku nadiifineyno inta ka hartay qoraalka si aan u sheegno waxtarka ay leedahay.

if($TempFileCount -eq 0)

Hadda waxaanu dejinaynaa bayaan shuruudaysan. Waxaad arki kartaa inay ku weydiinayso ‘if’. Haddii waa maxay? Haddi waxa gunta ku jira uu run yahay ama been yahay. Xirmooyinka ayaa muhiim ah, haddii kale haddii uusan garanayn waxa la barbar dhigo. Halkan, waxa lagu weydiinayaa haddii lambarka aanu ku kaydinay $TempFileCount uu la mid yahay eber.

The -eq waa gacanta gaaban ee siman Waa nooca isbarbardhigga. Waxay la mid tahay in carruurtaada loo sheego, “Haddii qolkaagu nadiif yahay, aad u fiican, wax baannu qaban doonnaa…†Hadalkani waxa uu leeyahay haddii lambarka lagu kaydiyey $ TempFileCount uu la mid yahay eber samayn shayga xiga.

{Write-Host "There are no files in the folder $TempFileLocation" -ForegroundColor Green}

Taasi waa waxa dhacaya haddii $TempFileCount uu eber yahay. Xirmooyinka curyaanka ah ayaa muhiim ah. Waxay u sheegaan PowerShell inay sameeyaan kaliya waxa ku jira gudaha haddii $ TempFileCount ay^{(TempFileCount)} la mid tahay eber.

Waxay u qori doontaa martida loo yahay, ama shaashadda, “Ma jiraan wax faylal ah oo ku jira galka C:\Users\username\AppdataLocal\Temp\*†. Halbeegga dhamaadka, " ForegroundColor wuxuu u sheegaa PowerShell inuu qoraalka ka dhigo cagaar. Taasi waxay fududaynaysaa in la kala saaro fariinta khaladka ah ee sida caadiga ah cas.

Macnaha kale waad garanaysaa. Tani waa, “Qolkaagu si fiican ha u nadiif ahaado ama haddii kale…… qayb ka mid ah hubinta haddii ilmahaagu nadiifiyey qolkooda. Waa waxa dhici doona haddii $TempFileCount aanu eber ahayn.

{$TempFile | Remove-Item -WhatIf -Confirm:$false -Recurse -Force -WarningAction SilentlyContinue -ErrorAction SilentlyContinue}

Tani waxay odhanaysaa tag meesha hadda lagu kaydiyay $TempFile . Xariiqda toosan ka dib waxaa loo yaqaan tuubo. Waxay u shaqeysaa nooc la mid ah dhuunta nolosha dhabta ah maadaama ay u sheegayso PowerShell inay ku shubto waxa ku jira $ TempFile gudaha cmdlet, sidii iyadoo biyaha lagu shubayo mashiinka dharka lagu dhaqo. Markaas cmdlet -ka saar-Shayga^{( Remove-Item )} ayaa sameeya waxa uu leeyahay; waxay meesha ka saartaa wax kasta oo meeshaas yaal.

Halbeegga -WhatIf ayaa aad muhiim u ah marxaladdan. Waxay u sheegaysaa PowerShell inuu socodsiiyo amarka, laakiin kaliya tijaabi, waxba ha saarin. Kaliya^(Just) na tus waxa dhici lahaa haddii aan runtii tan samayno.

Tani waxay kuu ogolaaneysaa inaad tijaabiso amarrada adiga oo aan waxba ka beddelin kombiyuutarkaaga. Ka tag meesha -WhatIf ilaa aad ku qanacsan tahay in qoraalku uu samaynayo waxaad rabto inuu sameeyo oo aan wax kale ahayn. Ka dibna kaliya tirtir taas oo qoraalka ayaa qabsan doona shaqadiisa.

Halbeegga -Confirm:$false waxay joojinaysaa qoraalka inuu ku weydiiyo inaad runtii rabto inaad tirtirto faylka. Waad ogtahay waxa -Recurse sameeyo. -Force macnaheedu waxa weeye tirtir wax kasta ha ahaatee. -WarningAction waxa lagu dejiyay SilentlyContinue .

Tani waxay ka ilaalinaysaa qoraalka inuu ku siiyo digniino ku saabsan waxa aad tirtirayso. -ErrorAction waxa loo dejiyay SilentlyContinue si haddii ay jirto nooc ka mid ah khaladka habka, ay u sii wada xajinayso.

Hadda waxaan joognaa safka ugu dambeeya.

Write-Host "Cleared $TempFileCount files in the folder $TempFileLocation" -ForegroundColor Green}

Sida Qoraa-Hostaga^(Write-Host) uu sameeyay markii ugu horeysay, waxay soo saari doontaa jumlada soo socota, si aan u ogaano waxa dhacay. Waxay noo sheegi doontaa inta fayl ee laga tirtiray galka ay hadda farsamaysay oo ku samee cagaar si ay u fududaato in la ogaado.

Aan wada eegno qoraalka:

Using PowerShell for Home Users – A Beginner’s Guide

Who doesn’t wish they could be a wizard and utter a few words to have magical things hаppen? Well, we’re not able to show you how to be a wizard, but we can show you how to do a little computer mаgic.

If you’ve got a Windows computer with Windows 7 on it, you’ve got PowerShell. Also, if you have a computer with Windows 7 on it, please update it for security’s sake.

But this article isn’t just for Windows people. The latest version of PowerShell is free and can be installed and used on Mac’s and Linux computers.

That’s important because what you learn about PowerShell can be used on almost any computer now. Who knows? You might take this skill to the next level and venture into a career in Information Technology.

What is PowerShell?

The high-tech answer from Microsoft is that it is a, “…command-line shell designed especially for system administrators.” Sounds intimidating. But it’s not. Do you take care of your computer? Yes, then you’re the system administrator in your house.

Do you tell your computer what to do with clicks and keystrokes? Yes, so think of the command-line shell as just another window that you type things in to tell your computer what to do. You can do this.

PowerShell is like a programming language, but not as cryptic as most. It really reads a lot like regular English, which was something Microsoft strove for so that it could be picked up by non-programmers.

It’s a way of writing a few lines of commands, called a script, to make the Windows operating system do something that you want it to do. Then, you can save those lines in a file and run it with a click or schedule it to run periodically.

What Can You Do with PowerShell?

The high-level point of PowerShell is to be able to automate tasks, so you don’t have to waste your time doing mundane things repeatedly. For a professional Systems Administrator, that could be something like creating new users, generating passwords for them, and send an e-mail with the details to their new supervisor.

Manually done, with clicks and typing, that process can take 5 minutes to as much as an hour or more. With the right scripts, the Systems Administrator may not even have to do any part of that.

But you want to know what you can do with PowerShell at home. Pretty much anything that you don’t like doing again and again. Use it to free up space on your hard drive by deleting temporary and log files you don’t need.

Put a curfew on your kid’s computer. Rename or organize a bunch of files. That’s the beauty of PowerShell. Almost anything you can do on your computer, you can create a PowerShell script to automate and run with a click or on a schedule.

How Do I Use PowerShell?

The easiest way to work with PowerShell is in the PowerShell Integrated Scripting Environment (ISE). You can find it by clicking on Start and typing powershell ise into the search bar in Windows 10. You should see it as shown below.

For the first time that we use it, we’re going to run it as the Administrator. To do this, you must first have administrator rights on your computer. In your Start Menu, right-click on PowerShell ISE, then click on Run as Administrator.

You may get a User Access Control (UAC) warning pop-up asking if you’re sure you want to do this. Click Yes.

Now you’re looking at the PowerShell IDE. The top pane of the window (1) is the scripting pane. This is where you will write your script. The bottom pane of the window (2) is the console area. When you test your script, you’ll see the output in this pane.

This is also where you’ll see error messages and such that will help you fix and make your scripts better. The pane on the right-side of the window (3) is the command add-on. Think of it as a dictionary of all the PowerShell commands available to you.

PowerShell comes set to not run any script other than those already a part of Windows. You’ll need to change it so that you can run your own scripts.

In the scripting window, copy and paste the following:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

The Set-ExecutionPolicy part of it is called a cmdlet (pronounced commandlet). Cmdlets are powerful things. Think of them as short commands that you can give Windows, and Windows will go do a bunch of more complicated stuff to satisfy your command.

An analogy would be telling your kid to clean their room. Short and to the point. If your kid is well-versed in room cleaning, then they will go and make their bed, put their laundry in the basket, shelve their toys and books, and maybe even vacuum the floor. They understand that the cmdlet Clean-YourRoom meant all that.

At the top of the window, you’ll see a green arrowhead. Click on that to run the command.

The -ExecutionPolicy part is telling Set-ExecutionPolicy what policy to set. It’s a parameter. It’s saying, “I want you to work within these guidelines and do specifically this. It tells it to use the specific policy of RemoteSigned.

The RemoteSigned policy states that PowerShell may not execute, or run, any script that was downloaded from the Internet unless it was signed by a trusted publisher.

In a roundabout way, it tells PowerShell that it’s fine to run any script created locally, because those don’t need to be signed by a remote trusted publisher. Now, your PowerShell script will be able to run any script you write on your computer.

Let’s look at a script to delete temporary files. It isn’t as powerful or thorough as CCleaner, but CCleaner comes with its own set of problems.

Use PowerShell to Create Space on Your Hard Drive

We’ll break down this script, line by line, so you can see how it works. At the end, the script will be shown completely so you can copy and paste it if you’d like.

$TempFileLocation = "C:\Users\username\Appdata\Local\Temp\*"

Anything with a dollar sign in front of it is a variable name. Think of it like a wallet to put valuable stuff in. Wallet reminds us of the dollar sign, valuables sounds like variable, so we’ll remember that too. We’re creating a wallet, or variable, named $TempFileLocation. The equal sign tells PowerShell what to put in that variable.

In this case, we’re putting in the location of a Windows’ temporary files location – C:\Users\username\AppData\Local\Temp\*. We’re doing this for two reasons; it’s a location that is always safe to delete files from, and we’re going to use it to tell PowerShell where it must go to delete files.

Where it says username in that location, swap it for your user name. That’s the user name that you use to log in to your computer. The asterisk (*) at the end of it is a wild card. What it represents is everything in the folder Temp, because everything in the Temp folder is temporary and we want to delete it.

The double-quotes around the location is important too. That tells PowerShell that what’s in there is a string. Think of string as a string of letters and characters. If it were ordinary numbers, we wouldn’t use the quotes.

$TempFile = Get-ChildItem $TempFileLocation -Recurse

We’re making another variable. This time we’re going to use a command to come up with something to put in the $TempFile variable.

Get-ChildItem 

Another thing you’ll notice about cmdlets like Get-ChildItem is that it is totally readable. See how the first word is a verb? Cmdlets all begin with action words, so you immediately know what it’s doing. ChildItem is two nouns.

The second part of the cmdlet is always going to tell us to what PowerShell will apply the action. ChildItem means all the children of a parent location. This is like saying get all the files that are in a folder, with files being the children and the folder being the parent.

What is the cmdlet getting the child items of? Everything in the variable $TempFileLocation. PowerShell is going to go to the location that we put in $TempFileLocation earlier and get all the child items that are there. Then, it will put them into the variable $TempFile.

So, what’s with the -Recurse part? That’s telling Get-ChildItem to go through everything in that location. Don’t just go get the files immediately inside the parent folder. If there are folders in that folder, get all their children too, and their children and so on. We’re going to get them all.

$TempFileCount = ($TempFile).count

Yes, we’re creating a third variable called $TempFileCount, and we’re going to put a number in that variable. Where’s the number? Well, ($TempFile).count is going to get us that number. You’ve probably figured out that the .count part is going to do the counting of all the files that we just stored in $TempFile.

Why did we do this? Mostly because it’s nice to know how many useless files we’re cleaning out with the rest of the script so we can tell how effective it was.

if($TempFileCount -eq 0)

Now we’re setting up a conditional statement. You can see that it’s asking ‘if’. If what? If the thing in the brackets is true or false. The brackets are important, otherwise the If doesn’t know what to compare. Here, it’s asking if the number we stored in $TempFileCount is equal to zero.

The -eq is the shorthand for equals. It’s a type of comparison operator. It’s like telling your kids, “If your room is clean, great, we’re going to do something…” This statement is saying if the number that was stored in $TempFileCount is -equal to zero do the next thing.

{Write-Host "There are no files in the folder $TempFileLocation" -ForegroundColor Green}

That’s the thing that will happen if $TempFileCount is zero. The curly brackets are important. They tell PowerShell to do only what is inside them if $TempFileCount equals zero.

It will write to the host, or the screen, “There are no files in the folder C:\Users\username\Appdata\Local\Temp\*”. The parameter at the end, –ForegroundColor tells PowerShell to make the text green. That just makes it easier to distinguish from an error message which is normally red.

Else

You know what else means. This is the, “Your room better be clean or else…” part of checking if your kid cleaned their room. It’s what will happen if $TempFileCount is not zero.

{$TempFile | Remove-Item -WhatIf -Confirm:$false -Recurse -Force -WarningAction SilentlyContinue -ErrorAction SilentlyContinue}

This says go to the current location stored in $TempFile. The vertical line after it is called a pipe. It does function kind of like a real-life pipe as it tells PowerShell to funnel the contents of $TempFile into the cmdlet, as though it was water being piped into a washing machine. Then the cmdlet Remove-Item does what it says; it removes whatever is at that location.

The -WhatIf parameter is very important at this stage. It tells PowerShell to run the command, but only try it out, don’t remove anything. Just show us what would happen if we really did this.

This allows you to test commands without changing anything on your computer. Leave the -WhatIf in there until you’re comfortable that the script is going to do what you want it to do and nothing else. Then just delete that out and the script will do its job.

The parameter -Confirm:$false stops the script from asking if you really want to delete the file. You know what -Recurse does. -Force means delete that thing no matter what. -WarningAction is set to SilentlyContinue.

This prevents the script from giving you warnings about what you’re deleting. -ErrorAction is set to SilentlyContinue so that if there’s any sort of error in the process, it just keeps chugging along.

Now we’re at the last line.

Write-Host "Cleared $TempFileCount files in the folder $TempFileLocation" -ForegroundColor Green}

Just like Write-Host did the first time, it’s going to output the following sentence, so we know what has happened. It will tell us how many files were deleted from the folder it just processed and do it in green to make it easy to spot.

Let’s look at the script altogether:

$TempFileLocation = "C:\Users\guymcd\Appdata\Local\Temp\*"
$TempFile = Get-ChildItem $TempFileLocation -Recurse
$TempFileCount = ($TempFile).count

if($TempFileCount -eq "0") { 
Write-Host "There are no files in the folder $TempFileLocation" -     ForegroundColor Green
}
Else {
$TempFile | Remove-Item -Confirm:$false -Recurse -Force -WarningAction SilentlyContinue -ErrorAction SilentlyContinue
Write-Host "Cleared $TempFileCount files in the folder $TempFileLocation" -ForegroundColor Green
} 

You can copy and paste this into your PowerShell ISE and save it as something like delete-TemporaryFiles.ps1. You may as well stick with the naming convention of cmdlets now that you understand them.

If the code is not working for you for some reason, you can also download the PowerShell script we created and just run it. Just unzip it first to view the script file.

Whenever you want to run this script, just right-click on it and choose Run with PowerShell. A PowerShell console will pop up for a second or two, while your script does its thing, and then will disappear if there are no errors.
