To ensure mp3gain process .mp3 files only in those directories that contain mp3 files, the first while loop + sort -u will single out the these directories. The second while loop will then cd into each of the directory to run mp3gain. I use sub-shell to cd to the directory so that I do not have to 'cd ..' back.
Code:
find /media/data/music -type f -name "*.mp3" |
while read f
do
echo ${f%/*}
done | sort -u | while read d
do
(cd $d && mp3gain -a -k -p *.mp3)
done
This may be a question for a different forum, but as I will need a script I thought I would start here.

I believe what is happening is rm is executing in the script on every directory and on failure of the first it stops although returns status 0.

hi,
i've been trying to figure this weird error but I cannot seem to know why. I am using below find command:

qmp3join - join mp3 files
SYNOPSIS
qmp3join [option]... file1 file2...
DESCRIPTION
qmp3join reads a list of mp3 files and joins them in one mp3 file in the specified order. some conditions must be met for the parameters of
each of the files (see NOTES section).
OPTIONS -f, --force
force join bypassing bit rate checks. by default, to join two files they must be both vbr (have variable bit rate) or have the same
bit rate. using this option you can skip this check.
-h, --help
show a brief help and exit.
-o <outfile>, --output=<outfile>
outfile is the name of the file where all the frames will be copied. if this option is not used, the frames from the second to the
last file of the list will be appended to file1.
-v, --verbose
show which operations are done.
-V, --version
show version and exit.
NOTES
(all) the following parameters are required to be common for two mp3 files to be joined: [fill this!!!]. also, about the bit rate parame-
ter, both mp3 must have the same value or (both) must have a variable bit rate. this restriction would be by-passable with the --force
flag.
before joining, all the streams are tested for validity. this is a time consuming operation.
in any case, qmp3join can be viewed like a better but restrictive cat for mp3 files, due to the mp3 file format characteristics.
BUGS
tests have been done only with mpeg version 1 layer iii streams, though it may (or not) work with other versions/layers.
