Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

create an archive of files with access time older than 5 days, and remove original files.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
tar -zcvpf backup_`date +"%Y%m%d_%H%M%S"`.tar.gz `find <target> -atime +5 -type f` 2> /dev/null | parallel -X rm -f

This deals nicely with files having special characters in the file name (space ' or ").

Parallel is from https://savannah.nongnu.org/projects/parallel/

Know a better way?

If you can do better, submit your command here.

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.
