Rename files using regular expression in linux

Question

I have a set of files named like:

Friends - 6x03 - Tow Ross\' Denial.srt
Friends - 6x20 - Tow Mac and C.H.E.E.S.E..s         


        

Answer 1

Edit: found a better way to list the files without using IFS and ls while still being sh compliant.

I would do a shell script for that:

#!/bin/sh
for file in *.srt; do
  if [ -e "$file" ]; then
    newname=`echo "$file" | sed 's/^.*\([0-9]\+\)x\([0-9]\+\).*$/S0\1E\2.srt/'`
    mv "$file" "$newname"
  fi
done

---

Previous script:

#!/bin/sh
IFS='
'
for file in `ls -1 *.srt`; do
  newname=`echo "$file" | sed 's/^.*\([0-9]\+\)x\([0-9]\+\).*$/S0\1E\2.srt/'`
  mv "$file" "$newname"
done
