The idea is to create a list of wav files and then cycle through
them, converting one at a time. For example,
for file in *.wav ; do
lame $file ${file%.wav}.mp3
done
The pattern "*.wav" creates the list.
The for..do..done loop interates down the list, assigning a new name
to the variable "file" each time.
The "lame" command converts the files. The ${//} syntax changes the
file ending from wav to mp3.
Personally, I'd add two extra items:
1) a check to see if the mp3 already exists. If it does, move on
the next wav file.
2) echo the lame command. This gives me a chance to review the
commands before I commit to them.
for file in *.wav ; do
[ -f ${file%.wav}.mp3 ] && continue
echo lame $file ${file%.wav}.mp3
done | sh
