Neat little script that implements find in pure python, this can be passed different patterns and directories. The script will walk the directories and match the patterns, it will then generate a list of files and get the ctime of each. Some comparison is done against a date you set and removes them. This is great for cleaning up application logs that clog up the filesystem. <\/p>\n
