Powershell Remove part of Video filename containing Square/Round brackets and everything inside those brackets

Question

I have several videos that has either round brackets and/or square brackets with some text inside those like (ANTYHING HERE) OR [ANTHING HERE]:

For example: MOVIENAME 2024 LANG [SOMETEXTHERE] 1080P.mkv or MOVIENAME 2024 (SOMEOTHERTEXTHERE) LANG [SOMETEXTHERE] 1080P.mp4 or

And by using Powershell with Regex text replacing, I wanna rename it to MOVIENAME 2024 LANG 1080P.mkv or MOVIENAME 2024 LANG 1080P.mp4 means I wanna remove any round and/or square brackets and anything inside those with also removing any extra spaces, meaning find & convert 2 or more spaces to just 1 space, possibly in single -replace pass or couple such passes at most.

I tried doing this just for square brackets, but it doesn't work:

$validExtensions = '.mkv', '.mp4'
Get-ChildItem -Recurse -File |
    Where-Object Extension -In $validExtensions |
    Where-Object Length -GT 500mb |
    Rename-Item -NewName {($_.BaseName -replace '(.*)(\[.*\])(.*)', '$1$3')}.ToUpper() + $_.Extension

Can anyone help achieving what I want here ?

Answer 1

Chain two -replace operations, as follows:

($_.BaseName -replace '[[(].*[])]' -replace '  +', ' ').ToUpper() + $_.Extension

• The first one removes any [...] and (...) tokens from the string .

  • Strictly speaking, it would also remove tokens with mismatched delimiters, e.g. [...)
  • If that is a concern, use the regex suggested by TheMadTechnician:
    '\[.*?\]|\(.*?\)'

• The second replaces runs of two or more spaces with a single space each.
