This uses bash's Process Substitution. It is necessary to give the full path of the file, thus why the filenames are filtered through realpath. In theory, this command should also work with mplayer and mplayer2 (using -playlist instead of --playlist). Modifications: - You can search specific directories by inserting them between "find" and "-type". - Edit the parameter of "-iname" to change the type of file searched for. - Remove everything after "realpath" to play the files in order.

Compare the content of the files in the current directory with files of the same name in the duplicate directory.
Pop Quiz: You have a duplicate of a directory with files of the same name that might differ. What do you do?You could use diff to compare the directories, but that's boring and it isn't as clever as find -print0 with xargs.Note: You must omit stderr redirect 2>/dev/null to see the list of missing files from DUPDIR, if any.Hint: Redirect stderr to a new file to produce a more readable list of files that are missing from DUPDIR.Warning: This doesn't tell you if DUPDIR contains files not found in the current directory so don't delete DUPDIR.Show Sample Output0find . -maxdepth 1 -mindepth 1 -print0 | xargs -0 -n 1 -I % cmp % /DUPDIR/% 2>/dev/null -
