Awk Renumber

Used to rename TV show episodes. Original files had episode number spanning the entire run of the show. Wanted to break it into season and episode numbers.

#!/bin/sh
#
# Input is list of files
# Argument is Season number
# Pipe the output to /bin/sh
#
awk '{mine=$0 ; sub(/e([0-9]+)/,"s0"SEASON"e"sprintf("%.2d",NR),mine); print "mv \"" $0 "\" \"" mine "\"" }' SEASON=$1

Preconditions

• Each season in a separate directory
• Each file has e[0-9]+ as episode identifier

Script

• For each file in the directory (in timestamp order)
• Replace episode number with the line number (with a leading zero if necessary)
• Print "mv ", the old name, and the new name
• Pipe it to /bin/sh
