Rename subtitles files according to tv shows names found in a directory

subtitles-renamer.sh

#!/bin/bash

# Renames subtitles files according to tv shows names found in a directory
# Acceped syntaxes for season/episode are: 304, s3e04, s03e04, 3x04 (case insensitive)
#
# Usage:
# Put this gist somewhere in your $PATH, like /usr/local/bin/subtitles-renamer
# Chmod +x it
# cd ~/YourHolidaysTvShowsWithSubtitles
# subtitles-renamer
#
# Note: zipfiles will be unzipped and .zip will be removed
#
# There are bashisms to work with regular expressions,
# so you really need bash or a shell compatible


# unzip files, maybe there are subtitles in it...
for f in *.zip; do
  if [ -e "$f" ]; then
    unzip "$f"
    rm "$f"
  fi
done

# switch into case insensitive
shopt -s nocasematch

# search subtitles
for f in *.{srt,ssa,sub} ; do
  if [ -e "$f" ]; then
    if [[ "$f" =~ s([0-9]+)e([0-9]+) || "$f" =~ ([0-9]+)x([0-9]+) || "$f" =~ ([0-9]+)([0-9][0-9]) ]]; then
      echo "Found '$f'"
      let SEASON="10#${BASH_REMATCH[1]}" # eventually delete leading 0
      EPISODE=${BASH_REMATCH[2]}


      # search for a matching film
      for movie in *.{avi,mkv} ; do
        if [ -e "$movie" ]; then
          if [[ "$movie" =~ ${SEASON}${EPISODE} || "$movie" =~ s0?${SEASON}e${EPISODE} || "$movie" =~ ${SEASON}x${EPISODE} ]]; then

            NEW_NAME=`echo "${movie%.*}.${f##*.}"`
            if [ "$f" = "${NEW_NAME}" ]; then
              echo "  Already ok"

Wonderful! Thank you.

can you add some code for extract RAR files, please

There are some issues with renaming S01E08 when you also have 1080p in the filename.

"Acceped syntaxes for season/episode are: 304..." This one conflict with 1080p in filenames (e08). Was unable to fix, so simply removed that option in the code:

if [[ "$f" =~ s([0-9]+)e([0-9]+) || "$f" =~ ([0-9]+)x([0-9]+) || "$f" =~ ([0-9]+)([0-9][0-9]) ]]; then
changed to
if [[ "$f" =~ s([0-9]+)e([0-9]+) || "$f" =~ ([0-9]+)x([0-9]+) ]]; then
_

if [[ "$movie" =~ ${SEASON}${EPISODE} || "$movie" =~ s0?${SEASON}e${EPISODE} || "$movie" =~ ${SEASON}x${EPISODE} ]]; then
changed to
if [[ "$movie" =~ s0?${SEASON}e${EPISODE} || "$movie" =~ ${SEASON}x${EPISODE} ]]; then

Awesome, Thanks.

Also, @isevcik this:

I would suggest to change order in condition:

if [[ "$f" =~ s([0-9]+)e([0-9]+) || "$f" =~ ([0-9]+)x([0-9]+) || "$f" =~ ([0-9]+)([0-9][0-9]) ]]; then

helped too.

awesome!!! thanks
