Delete more than one month old thumbnails from home directory

By time thumbnail images in ~/thumbnails take up too much space, this command will help deleting old ones.

Find options explained:

-type f : find files only, not directories

-atime +30 : last accessed more than 30 days ago


There are 2 alternatives - vote for the best!

What others think

You can already set a space quota, and also maximum age for Nautilus thumbnails with gnome config editor. Easier ;)

find ~/.thumbnails/ -type f -atime +30 | xargs rm -f

Plus, you don't need to pipe it to xargs:

find ~/.thumbnails/ -type f -atime +30 -exec rm {} +

Actually, I forgot, find has a delete action:

find ~/.thumbnails/ -type f -atime +30 -delete
