$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)
Try this,
$oldString = [REGEX]::ESCAPE('Z:\next\Core\Resources\')
You need escape the pattern to search for.
This works:
$Source = 'Z:\Next\ResourceConfiguration.config'
$Dest = 'G:\PublishDir\next\ResourceConfiguration.config'
$RegEx = "Z:\\next\\Core\\Resources"
$Replace = 'G:\PublishDir\next\Core\Resources'
(Get-Content $FilePath) | Foreach-Object { $_ -replace $RegEx,$Replace } | Set-Content $Dest
The reason that your attempt wasn't working is that -replace
expects it's first parameter to be a Regular Expression. Simply put, you needed to escape the backslashes in the directory path, which is done by adding an additional backspace ( \\\\
). It expects the second parameter to be a string, so no changes need to be done there.
