Delete all files older than X days

Sometimes you just need to prune a directory of all files older than a certain age. Think log files, or uploaded files... maybe ~/Downloads, perhaps?

find . -mindepth 1 -maxdepth 1 -mtime +90 -delete

• mindepth and maxdepth stop find from crashing if there are too many files
• mtime specifies instructs find to filter the files by the last modified time. +90 means 90 days
• delete is self-explanatory
