Batch Replace Character in File Names

Question

I have about 600 video files with the $ special character in the title.

I want to batch replace this with a letter s.

I found the powershell code online below and it works fine with replacing letters with other letters but fails when trying to replace the $ special character

get-childitem -recurse | rename-item -newname { $_.name -replace "",""}

I tried using the code below and it ends up adding an s to the end of the file type instead of replacing the $

get-childitem -recurse | rename-item -newname { $_.name -replace "$","s"}

$hortvid.mp4 becomes $hortvid.mp4s instead of shortvid.mp4

Any ideas on how to get this to work correctly?

Answer 1

Just use \ escape character:

When running line in the directory:

get-childitem -recurse | rename-item -newname { $_.name -replace "\$","s"}

input file:

$hortvid.mp4

output file is renamed:

shortvid.mp4
