[Solved] Need help with a basic shell scripting query using 'sed'.

PingPing · 2009-10-10 14:36:24

I've never used sed before but my problem is this:

1. I have about 40+ files all with the extension .flv.mp3 in a directory.
2. I want to change the extension from .flv.mp3 to just .mp3.

What's the best way of doing this?

man rename

rename .flv.mp3 .mp3 *.flv.mp3

and it may be solved.

but using sed is a bit different but very possible.

you can create a script with a loop (for/while).

for all of those files, u just need to do this:

#! /bin/bash
# by quarkup™
for filename in `ls *.flv.mp3`
do
target_name = `echo $filename | sed -e 's|\.flv\.mp3$|\.mp3|g'`
mv $filename $target_name
done
return 0

quite simple

anyway, you got the package "file-rename-utils" in the AUR which provides you the "mv_sed" executable (script) and another ones which may help you on another times.

or in bash-isms only:

#!/bin/bash
for file in *.flv.mp3; do
    mv "$file" "${file%.mp3}"
done

Thanks very much everyone. I went for the simplest option:

rename 's/flv\.mp3/mp3/' *.flv.mp3

but many thanks for the shell scripting advice. I'm sure I'll have cause to use it in the future.
