subrenamer

Bash and perl rename based file renamer for subtitles and other files where you want to match the format of another group of files with a fixed numbering scheme

Dependency

GNU grep

prename (In some distos this is called rename, but in Fedora rename is the util-linux rename. You can do alias prename=rename)

Usage

rename.sh \
  -e subtitle episode regex [(?<=\[)\d\d(?=\])] \
  -x sub extension regex [\..*] \
  -t video episode regex [(?<=\[)\d\d(?=\])] \
  -f video extension [mkv] \
  -s subtitle extension [ass] \
  -p padding renamed number to length of N with zeros [] \
  -v verbose \
  -n dry run

Example

If one has the some files like where the each mp4 file contains a HASH

.
├── Title Part 1 #01 Title Part 2 [25F9E8E6].mp4
├── Title Part 1 #02 Title Part 2 [63710608].mp4
├── Title Part 1 #03 Title Part 2 [FFB297D4].mp4
├── subname part 1 01 subname part 2.sc.ass
├── subname part 1 01 subname part 2.tc.ass
├── subname part 1 02 subname part 2.sc.ass
├── subname part 1 02 subname part 2.tc.ass
├── subname part 1 03 subname part 2.sc.ass
├── subname part 1 03 subname part 2.tc.ass

then you can use rename.sh -e '(?<= )\d\d(?= )' -t '(?<=#)\d\d)' -f mp4' which will create a folder under the current working directory named done and contains the renamed subtitles hardlinked to the original subtitles

Tip

Use -nv to test run the rename

Note

It's rarely needed to use the -x option unless the file names part contains dots that aren't part of the extension

Note

For the most common type of files, where videos are mkv, subtitles are ass, and all episode names are two digit numbers surronded by [], the default options should just work
