I have a lot of files and directories named similar to [Origin]Description[Techinfo].

Sometimes, brackets can be round brackets instead of square brackets, or spaces between the parts. How can I rename (ideally recursively) the files that I get something like

script or function [Origin]Description[Techinfo] ---> Description[Origin][Techinfo] ?

I can access the NAS via SSH, it runs FreeBSD (FreeNAS). Or I could do it via a client (Linux or Windows).

  • You have to individuate each single possibility to create a regex. The ones with spaces will be the most difficult because you cannot know in advance if a space belongs to the description or to the Techinfo. But it will be a secondary problem. Is the full list Are a full list of descriptions or of TechInfo available somewhere? – Hastur Feb 7 '15 at 11:42
  • I'm seeing bash in your future, perhaps awk, sed, perl... – Xen2050 Feb 7 '15 at 11:45
  • @Hastur: No, no full lists. We are talking about media files, with arbitrary naming. I am looking for something which identifies the three blocks, based on the brackets, and just swaps from ABC to BAC. – emk2203 Feb 7 '15 at 11:52

Windows, powershell V2, [Origin]Description[Techinfo] -> Description[Origin][Techinfo]:

powershell (ls -Re -Fo -Fi "*[*")^|%{$f=$_.Name -split('[\]\[ \)\(]');$r='\'+$f[2]+'['+$f[1]+']['+$f[3]+']';[IO.File]::Move($_.FullName,$_.DirectoryName+$r)}
  • I am a complete rookie with powershell, so I just copied and pasted it and ran it in a test directory. This is what I got: 'Exception at call of "Move" with 2 argument(s): "An empty filename is not allowed. Parameter name: sourceFileName" In line:1 character:109 + ... ']['+$f[3]+']';[IO.File]::Move($_.FullName,$_.DirectoryName+$r)} + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : ArgumentException' – emk2203 Feb 7 '15 at 20:14
  • @emk2203 run as command or script? – STTR Feb 7 '15 at 20:43
