Remove all files previously extracted from a tar(.gz) file.

xargs deals badly with special characters (such as space, ' and "). To see the problem try this: touch important_file touch 'not important_file' ls not* | xargs rm Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.

archive all files containing local changes (svn)

xargs deals badly with special characters (such as space, ' and "). In this case if you have a file called '12" record'. Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem. Both solutions work bad if the number of files is more than the allowed line length of the shell.

remove unneeded configuration files in debian

This will, for an application that has already been removed but had its configuration left behind, purge that configuration from the system. To test it out first, you can remove the last -y, and it will show you what it will purge without actually doing it. I mean it never hurts to check first, "just in case." ;)
