Bulk/Batch-rename files with different endings (NOT change the endings)

Question

My Problem, that I've got a folder with many different files like:

xxxxxxxxx.avi       yyyyyyy.jpg         zzz.txt

And I want to rename them into

001.avi  002.jpg  003.txt

It's not working with thunar rename, because the filenames are not all the same length.

Maybe with rename 's/.*......, but I am kinda stuck...

Thanks for any suggestions

Answer 1

If you are comfortable with a command line solution, you could do something like this, in bash

i=1
for file in *.*; do
  printf -v newfile "%03d.%s" $((i++)) ${file##*.}
  echo mv -v -- "$file" "$newfile"
done

The echo will prevent it from actually making any changes (it will just output a list of mv commands that it would make) - you can actually make the changes by running the same command without the echo once you are satisfied that it's going to do what you want.

GwenRename is a series renaming tool. It was created as an external tool for GwenView, the image viewer for KDE, but can also be used from Konkueror. As that, the files to be renamed are passed to it as command line parameters, and there is no other way to load files into it.

The main goal is to have a batch renaming tool that's easy and light enough for every day use. If you are looking for a more compound and featured renaming tool, you should have a look at Dominik Seichter's KRename.

pyRenamer is a mass file renamer, written in PyGTK.

Found another rather short solution:

  n=0; for f in * ; do mv "$f" "$n.${f/*./}"; n=$((n+1)); done
