+7 will then remove the files older than 168 hours. find command is more powerful than you can really imagine. However, I've just tested that and it looks like it doesn't only rely on the date info, but also on the hours and minutes. The -mindepth 1 prevents the base directory from matching (I assume you don't want /media/nas/Security from being deleted). In order to delete files older than X number of days, try using Unix find command. When testing (before you actually use -delete to make sure find gets things right) make sure to add -depth so that your test also descends firstĭon't forget that position is important in find's arguments, -delete isn't an option to delete matches, it's an action to delete what has been matched (so don't put -delete at the start). It is advisable to run the above command first, to see what files are selected.

Optionally, you can specify -print at the end of the command, but that is the default action. This will find all files older than 15 days and print their names. delete implies -depth so that sub-directories are entered first otherwise if a directory matched then it would try deleting the directory before descending into it (which will fail if the directory isn't empty). 5 Answers Sorted by: 97 You could start by saying find /var/dtpdev/tmp/ -type f -mtime +15. a.out at the end.įind can delete files that it has found with -delete though it won't delete directories unless they are empty. In any case, for both -find -mtime +30 and zsh 's m+30 glob qualifier, note that it selects files that are 31 days old or older, as it compares the age in terms of integer number of days. in front of the names, find always gives the path to each item) and then find puts. oldfiles (/h/USER/.txt (NDm+30/)) if ( (oldfile)) then rm -f - oldfiles else echo >&2 No text files to del fi. name a.out -exec echo rm -rv * +Īs you can see, * has been expanded by the shell to a.out gtktest.c (you can tell the shell did this rather than find by the fact that they don't have.
