Hello!

 

Below is a function that will search in a string and replace a character in a variable. Simple enough. It generally saves time in calling this from a helper file in source control for tidying up variables that are passed in to a Powershell function that aren’t quite formatted as required. A good example of this is upstream build variables with spaces in TeamCity.


Function FormatReplaceVariable
{
[CmdletBinding()]
param([parameter(Mandatory=$true)]
[string]$param,
[string]$find,
[string]$substitute)

Write-Host "Replacing characters $find with $substitute in $param" -Verbose
$param = $param -replace "$find", "$substitute"
Write-Host "Now parameter looks like $param" -Verbose
return $param
}

$bob = FormatReplaceVariable -param "as'lfjksaj'JASD;oasdjf'asd aasd asd; ghas'fkasdf;aksd" -find ";" -substitute "!!!!"
write-host $bob
