# fixes file encoding based on file size:
# fixfile.sh file*
#
# e.g fixfile.sh 03.\ Needs\ M*
#
# okay so this is pretty simple
# basically it compares filesizes between $1 and $2
# it works best with glob selection in your shell
#
# it's a filename encoding fixer basically
# that fixes files being read incorrectly as the wrong file name 
# for example in a torrent client
