脚本循环段

Question

mode con: cols=52 lines=16
while ($script -ne "Q") {
$tag = ""
while (-not ($tag)) {
$tag = Read-Host 'Enter tag # or Q to quit'
$date = get-date -f MM-dd-yyyy_HH_mm_ss
$username = [Environment]::Username 

if(!(Test-Path -path "C:\Users\$username\Desktop\PSTools\Screenshot Dump\")) {
New-Item "C:\Users\$username\Desktop\PSTools\Screenshot Dump\" -type directory
}

}

if ($tag -eq "Q"){break}

cls

#$ErrorActionPreference = 'silentlycontinue'

cd "C:\Users\$username\Desktop\PSTools"

set-alias psexec "C:\Users\$username\Desktop\PSTools\PsExec.exe"

set-alias nircmd "C:\Users\$username\Desktop\PSTools\nircmd.exe"

------>LOOP START HERE

psexec \\$tag -i -c -s nircmd savescreenshotfull "C:\$tag-$date.png"

move "\\$tag\c$\$tag-$date.png" "C:\Users\$username\Desktop\PSTools\Screenshot Dump\$tag-$date.png"

explorer "C:\Users\$username\Desktop\PSTools\Screenshot Dump\$tag-$date.png"

------>LOOP END HERE

"`n"
}

基本上，我试图在上面提到的地方循环，但我习惯于在命令提示符中这样做，这是不一样的。我想让它循环X次或直到我CTRL+C退出它。

Answer 1

您也可以使用Foreach循环。假设您想循环5次：

$NumberOfLoops = 5
Foreach ($loop in (1..$NumberOfLoops)) { Do Loopy Stuff }

Answer 2

您可以使用basic FOR语句到循环。不过，PowerShell有一些很棒的循环技术。值得一看..。

对于一个基本For循环的例子，只需这样做(will循环10次($x=0-9))：

FOR ($x=0; $x -lt 10; $x++) { DO LOOPY STUFF };
