Change shortcut links to new location
Hello All,
I'm currently trying to get the following script to work, but need to adjust it to match anything with "\\server1\IT". Using -eq works perfectly for folders, however when using -match I get the following error.
parsing "\\server1\IT" - Unrecognized escape sequence \I
Script should change files and folders location. Ex "\\server1\IT\Document.doc
# Call wscript com object
$shell = new-object -com wscript.shell
$oldsharepath = "\\server1\IT"
# Recurse through directories for .lnk files
dir 'D:\Test Server1' -filter *.lnk -recurse | foreach {
$lnk = $shell.createShortcut($_.f
$oldPath= $lnk.targetPath
# If match text, perform operation
if($oldpath -match $oldsharepath)
{
write-host "Match: " + $_.fullname
remove-item $_.fullname
$lnknew = $shell.createShortcut($_.f
$lnknew.targetPath = "`"\\newserver\share1`""
$lnknew.IconLocation = "%SystemRoot%\system32\SHE
$lnknew.Save()
}
}
Write-Host "End..."

Probably the simplest solution is to double the backslashes when they appear in patterns.
But for you, you're not really using a regular expression, you're just checking to see whether two strings are equal for the length of the shorter string, so you could do better with:
But for you, you're not really using a regular expression, you're just checking to see whether two strings are equal for the length of the shorter string, so you could do better with:
if($oldpath.substring(0,$oldsharepath.length) -eq $oldsharepath)
-match is the regular expression matching operator, so you must use regular expression syntax. In a regular expression, the backslash is the escape character.
You want to do a partial match here. The easiest way is to the -like operator instead, which uses a much more simple syntax:
To do this in a regular expression, a partial match at the beginning of the string would be written as:
The caret matches the start of the string, then you put the literal string. Problem in your case is that it's a variable, so you can't tell in advance what kinds of special regex characters might exist.
Luckily there's a programmatic way to escape any special characters so you know you match the literals:
So your match would then look like this:
Or, broken out more:

[RegEx]::Escape($string)
So your match would then look like this:
if($oldpath -match "^$([RegEx]::Escape($oldsharepath))")
{ }
Or, broken out more:
$reg = "^" + [RegEx]::Escape($oldsharepath)
if($oldpath -match $reg)
{ }
