[PowerShell每日技巧]查看PATH环境变量(20131217)

DAIC

The environment variable $env:Path lists all paths that are included in the Windows search path when you launch an application. Likewise, $env:PSModulePath lists all paths PowerShell searches for PowerShell modules (and includes in its module auto-loading).

These variables contain semicolon-separated information. Use the operator -split to view the paths separately:

PS> $env:path -split ';' C:\Windows\system32 C:\Windows C:\Windows\System32\Wbem C:\Windows\System32\WindowsPowerShell\v1.0\ PS> $env:PSModulePath -split ';' C:\users\DAIC\My Documents\WindowsPowerShell\Modules C:\Windows\system32\WindowsPowerShell\v1.0\Modules\

$aaa = (dir env:userprofile).value     ------赋值给变量aaa
