使用PowerShell設定系統變數與ps1範例

以下ps1範例包含系統時間格式、程式(標準/錯誤)輸出重導、外部程式呼叫與ps1變數使用

$datestr = Get-Date -format yyyMMdd
$reporttype = "COMP"
$folder = "D:\reportFolder\"
$toolpath = "D:\scripts\Report.php"

$log = '{0}logs\{1}_{2}.log' -f $folder, $reporttype, $datestr
$err = '{0}logs\{1}_{2}.err' -f $folder, $reporttype, $datestr
php.exe $toolpath type=$reporttype folder=$folder >>$log 2>>$err

PowerShell ps1之語法遠優於舊有的bat，使用上更為便利與靈活、更為易讀。


直接透過PowerShell永久設定系統環境變數之指令
# example of adding a path to PATH
[System.Environment]::SetEnvironmentVariable("PATH", $Env:Path + ";C:\Program Files (x86)\PHP", "Machine")

# creates “myY” of category “User”, and set the value to “"la la"”
[Environment]::SetEnvironmentVariable("myY", "la la", "User")

# removing a env var from registry
[Environment]::SetEnvironmentVariable("myY", $null, "User")

# show value of “path”
$env:path
