Question

$FilePath = 'Z:\next\ResourcesConfiguration.config'
$oldString = 'Z:\next\Core\Resources\'
$NewString = 'G:\PublishDir\next\Core\Resources\'

Any Idea how can you replace a string having : sign in it. I want to change the path in a config file. Simple code is not working for this. tried following

(Get-Content $original_file) | Foreach-Object {
 $_ -replace $oldString, $NewString
 } | Set-Content $destination_file

The Replace operator takes a regular expression pattern and ‘\’ is has a special meaning in regex, it’s the escape character. You need to double each backslash, or better , use the escape method:

$_ -replace [regex]::escape($oldString), $NewString

Alterntively, you can use the string.replace method which takes a string and doesn’t need a special care:

$_.Replace($oldString,$NewString)
