Trying to use a convoluted for loop with VLC and Parallel or OpenMPI with no success. Help?
I have about 12,000,000 mod files I'm trying to turn into a test of "unlimited cloud storage" by running them all through VLC and blowing them into mp3 files. I can get this to work serially but when trying to use openMPI or Parallel, something in the syntax is tripping it up some. Here is an example of the command I'm using. Open to any help or suggestions.
Code:
for file in `find ./modarchive/modarchive_2007_official_snapshot_addendum1/ -name "*.mod" -type f`; do parallel -j4 --citation NEWFILE=`echo $file | sed 's/modarchive/mp3archive/'`;echo working on $file; vlc -I dummy -f $file --sout "#transcode{acodec=mp3,ab=128}:standard{mux=mp3,dst=$NEWFILE.mp3,acce~ss=file}" vlc://quit 2> /dev/null ; done

codechanges
codechanges(1) General Commands Manual codechanges(1)NAME
codechanges - computes the amount of code changes between two code trees or single files
SYNOPSIS
codechanges [-n] old-directory new-directory
codechanges [-n] old-file new-file
DESCRIPTION
codechanges recursively compares the two named directories (or files) calculating new/deleted/changed lines, not including comments or
blank lines, in files which appear to be source files (C, C++, shell, and Makefiles). To include comments and blank lines, use the -n
option.
APPLICATIONS
codechanges is purpose designed to measure the amount of code change between milestones in a project's life. The following output is from
two stages, plus some artificial test cases, in the pmccabe code stream:

DIAGNOSTICS
There aren't many at this time.
BUGS
codechanges thinks it knows what source files are interesting and the user may not agree with its choices. It's a script and should be
easy to modify. Ultimately this should probably be configurable.
codechanges uses a program called decomment which guesses how to de-comment a file based on its file name and it's not always perfect.
