quick shellscript

icecubeflower · 07-09-2009, 03:08 AM

Anybody know shellscripts?

Suppose this converts an mp3 to a wav:
mpg123 -w song.wav song.mp3

Can anybody write me a little shellscript to convert all mp3's in the same directory as the shellscript to wav's?

I still never learned shellscripts. Probably I should get around to that someday.

You don't need much scripting for that. I am not familiar with mpg123, but the general idea if you use bash as your shell would be this:

Code:

for file in *.mp3; do lame --decode "$file" "${file/.mp3/.wav}"; done

Change "lame --decode" by whatever you want. I prefer to use lame just because I am familiar with it.

or you could also

for file in *.mp3
do
lame --decode "$file" "${file%.*}.wav"
done

Indeed!! Eventually you will find that writing your own is more efficient than trying to persuade others to do it for you.

I would start with the "Bash Guide for Beginners" by Machtelt Garrels. Free at http://tldp.org
