I often find the need to dynamically frame a command syntax and run the ultimate command:
Sample Script:
$var = 10
$cmd = "write-host $var"
Write-Host "Command is: $cmd"
Write-Host "Command Result is: "
invoke-expression -command "$cmd"
Script Result:
PS C:Temp> .Run-commands-via-variables.ps1
Command is: write-host 10
Command Result is:
10
PS C:Temp>
Sample Script#2:
param ([String]$msg)
$cmd = "write-host $msg"
Write-Host "Command is: $cmd"
Write-Host "Command Result is: "
invoke-expression -command "$cmd"
Script Result#2:
PS C:Temp> .Run-commands-via-variables.ps1 Message
Command is: write-host Message
Command Result is:
Message
PS C:Temp>
