What Others Think

This command is dangerous because of xargs: mkdir a echo foo > 'a/dont keep_this' echo foo > 'keep_this' # wait 5 days tar -zcvpf backup_`date +"%Y%m%d_%H%M%S"`.tar.gz `find a -atime +5` 2> /dev/null | xargs rm -fr ; This will remove the file keep_this and will not backup 'dont keep_this'.

Hi unixmonkey8046, thanks for your comment. Note that with special char also tar will have some problem, in fact in your example you will also back up the file 'keep_this' created outside of the directory 'a'. You need to take care in any case your files have some special character. The problem is not xargs, you can quote the strings which you pass to it.

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
