I've a series of media files I'm trying to rename en mass.

001 - 01x01 - mediaTitle1.avi
002 - 01x02 - mediaTitle2.avi
003 - 01x03 - mediaTitle3.avi

What I'd like is to output:

Series Title S01 E01 - mediaTitle1.avi
Series Title S01 E02 - mediaTitle2.avi
Series Title S01 E03 - mediaTitle3.avi

I'm trying this:

for f in *01x*; do echo mv -v "$f" "Series Title S01 E{f#1}"; done

But it's failing. So I want to keep the end of the file and replace the beginning for each file

  • You can use the rename command. Filenames have spaces?

You are close, but forgot(?) to put $ at variable expansion, try:

for f in  *01x*; do mv -v -- "$f" 'Series Title S01 E'"${f#*01x}"; done

Notice single quotes in target file due to spaces in filename.

  • Holy moly... It worked.. but I had to remove: "-v --" Not sure why...

  • @Beertastic -v is just verbose flag, and -- informs mv that it is the end of options and all next arguments will be filenames. This allow to pass files with - in their names, e.g. -abc.txt. It really should work with both those flags.

  • @jimmij Neither -v nor -- are specified by POSIX, so it's possible Beertastic is on a platform that doesn't support them (e.g. Busybox, Solaris). Commented Jan 22, 2015 at 18:04
  • Isn't -- part of a general POSIX specification for all commands that do normal option processing? Probably it's just -v that had to be removed.

cd /path/to/avidir; mkdir ../avidir2
pax -rwls '|.* - \(..\)x\(.. - \)|Series Title S\1 E\2|' *.avi ../avidir2

The above command will create hard-links to all of your files in another directory. This enables you to verify all of the changes are to your satisfaction before removing the files with the unwanted names.
