Powershell Get-Process字符串作为名称

Question

When using Get-Process how can I use a string as -Name?

$program = "MyProgram"
Get-Process $program

Instead of

Get-Process -MyProgram

Answer 1

Powershell will accept the name, no matter what.

Get-Process Firefox

Will return all running Firefox. Likewise, arrays will work too:

Get-Process Firefox, iexplore

Or

$Proc = @("Firefox","iexplore")
Get-Process $Proc

Declares an array explicitly, then checks for each running process.

Of course, as previously stated, you can and should use -Name for clarity. But nothing really changes. The script should still read something like:

$Proc = @("Firefox","iexplore")
Get-Process -Name $Proc

There is also the Where-Object approach:

Get-Process | Where-Object {$_.Name -eq "Firefox"}

To do "stuff" with it, just pipe the objects into a script block.

Where-Object:

PS C:\> Get-Process | Where-Object {$_.Name -eq "Firefox"} | fl $_.ID

Returns:

Id      : 7516
Handles : 628
CPU     : 1154.1421983
Name    : firefox

get-process $Proc | FT ID, Name

Would return:

    Id Name
    -- ----
    7516 firefox
    12244 iexplore
    12640 iexplore

Or, you could finally use the ForEach-Object as mentioned, and loop through them:

Get-Process $Proc | ForEach-Object {If($_.Path -contains "C:\Program Files*"){Write-host "Bad Directory"} else{ write-host "Safe"}}

If the running .exe above is running from C:\\Program Files* then its writes out "Safe", otherwise it writes "Bad Directory".

Answer 2

Seems by popular agreement, the answer to your question is to provide a string array for the -Name parameter of Get-Process like so:

Get-Process -Name MyProgramA,MyProgramB

You can then loop through using the pipeline:

Get-Process -Name MyProgramA,MyProgramB | ForEach-Object {$_}

You can also use a variable:

Get-Process -Name $MyProgramStringArrray
