im trying to create a bash to automate rename files from, if for an anime:

Example:

[TAG] One Piece - 01 [Quality].mkv

to:

[TAG] One Piece - S01E01 [Quality].mkv

But this isnt always because i follow TheTVDB season and episodes, i was using this scrapper for Plex (https://github.com/ZeroQI/Absolute-Series-Scanner) but know im using Emby and need to be renamed following TheTVDB format.

Another example:

[TAG] One Piece - 872 [Quality].mkv

to:

[TAG] One Piece - S19E93 [Quality].mkv

Edited, because first time i didnt explain weel.

To sum up i want to do something like the scrapper but renaming files if possible.

Assumptions:

1. Files to be renamed are all of the form [<tag>] <name> - <serial> [<quality>].mkv.


2. 
   

   Each anime has a lookup file called <name>.lst, listing the episodes in serial order, e.g. One Piece.lst contains:

   
   
   

   S01E01
   S01E02
   ...
   S01E08
   S02E01
   ...
   

   
   



3. You use a bash shell at version 4 (minimum).

Here's the script to canonicalize your anime vids:

#!/bin/bash
# USAGE: canon_vids <dir> ...
# Canonicalize the filenames of all MKV vids in each <dir>

# All the anime lookup tables are in the lookup subdirectory
# where canon_vids is stored
lookup_dir="$(dirname "$0")/lookup"

log_skip() 
 echo "SKIP ($1): $2"


find "$@" -name *.mkv | while read f; do
 # Check filename against our desired pattern
 # (We don't want to rename what's already been renamed!)
 if [[ $f =~ /([[^]]+]) (.*) - ([0-9]+) ([[^]]+].mkv) ]]; then
 # We've now split our filename into:
 prefix="$BASH_REMATCH[1]"
 name="$BASH_REMATCH[2]"
 serial="$BASH_REMATCH[3]##0"
 suffix="$BASH_REMATCH[4]"
 # Some sanity checks
 if (( serial <= 0 )); then
 log_skip "$f" "Invalid serial# '$serial' for $name"; continue
 fi
 # Let's look up the episode
 episode="$(sed -n $serialp "$lookup_dir/$name.lst")"
 if [[ -z "$episode" ]]; then
 log_skip "$f" "Can't find serial# '$serial' for $name"; continue
 fi
 mv -vn "$f" "$f%/*/$prefix $name - $episode $suffix"
 fi
done

And here's a bonus script that generates those lookup files, given the number of episodes in each season:

#!/bin/bash
# USAGE: generate_series <#eps> ...
while [[ $1 ]]; do
 ((s++))
 for e in $(seq "$1"); do
 printf "S%02dE%02dn" $s $e
 done
 shift
done

And to test it all:

$ ls
canon_vids generate_series

# Create One Piece lookup table
$ mkdir lookup
$ ./generate_series 8 22 17 13 9 22 39 13 52 31 99 56 100 35 62 49 118 33 96 > lookup/One Piece.lst
$ tail -n lookup/One Piece.lst
S19E92
S19E93
S19E94
S19E95
S19E96
$ wc -l lookup/One Piece.lst 
874 lookup/One Piece.lst

# Create fake One Piece MKVs (adding a couple more to trigger errors)
$ mkdir op
$ for i in $(seq 0 876); do touch "$(printf "op/[TAG] One Piece - %02d [quality].mkv" $i)"; done
$ ls op | wc -l
877

# And now, the moment of truth...
$ ./canon_vids op

...

renamed 'op/[TAG] One Piece - 278 [quality].mkv' -> 'op/[TAG] One Piece - S11E52 [quality].mkv'

# OK, but what happens when we run it again? Will our files be further renamed? Will Luffy find One Piece?
$ ./canon_vids op 
SKIP (op/[TAG] One Piece - 00 [quality].mkv): Invalid serial# '0' for One Piece
SKIP (op/[TAG] One Piece - 875 [quality].mkv): Can't find serial# '875' for One Piece
SKIP (op/[TAG] One Piece - 876 [quality].mkv): Can't find serial# '876' for One Piece

# Of course! Those files were never found in the lookup table, so they're still
# candidates for renaming. More importantly, no other files were touched.
