Bash script help needed

[trenton]

Hi all

I have a dir full of HE-AAC V2 files that I would like to put in .m4a containers with mp4creator, using this command;

mp4creator -create=*.aac *.m4a

where * is the file in the dir.

There are spaces in the file names.

That command needs to run for each file.

Any help please.

for FILE in *.aac
do
echo "Starting with file: $FILE ...\c" # might have to use echo -e
BFILE=`echo $FILE | awk -F. '{print $1}'` # or, `basename $FILE .acc`
mp4creator -create=$FILE $BFILE.m4a
echo " Done."
done

Something like that. More info here:http://www.linuxtopia.org/online_books/advanced_bash_scripting_guide/index.html

Briliant, thank you very much.

As soon as I can see straight I'll try that.

I would just do:

for FILE in *.acc
do
BFILE=${FILE%.*}
mp4creator -create="$FILE" "$BFILE.m4a"
done

Note that because the filenames have spaces it's important to surround $FILE and $BFILE with quotes - otherwise the name gets broken into multiple command line options..

Oh yeah. Quotes

I ripped about a gig of trance from DI-FM, and dreaded fixing each by hand.
I tried the first solution but errored out. My blood was up so I looked for a solution and found krename to fix the spaces.
After that the script work fine.
But will be using the second solution from now.

Thanks redarrow & Nod

I don't have much experiance with scripting, but you can also use sed.

eg. ls *.aac | sed -e 's/\ /\\\ /g'

That should output the directory listing with spaces escaped. Thou I don't know how to take the output from above and put it into "mp4creator -create=*.aac *.m4a" elegantly.

You could use the resulting list as input for a loop (while read FILE;<something>;done < `your command`)
