==Clean Up After Yourself==
Every so often, some spring cleaning is useful.  We have an app for that.
=====clean_me.py=====
Available to everyone in the FMRI usergroup on Hoffman2, this script was designed to find certain types of pesky files that have been known to build up over time but aren't actually necessary:
* ''.DS_store'' files
* Empty directories
* tsplots
* Empty files
* Extended Attributes
* mat files
and it gives you the option of deleting them.
To run it, just change into the directory you wish to clean and use the command:
$ clean_me.py
<!--==When it Hits the Fan==
[[File:Hoffman2-ButtonPress.gif]]
You tried to remember to clean up your files, you even kept a large dataset on your computer last weekend instead of working with it on Hoffman2.  But still your quota, or your group's quota was reached.  How does one fix this?
# First things first, run <code>clean_me.py</code>
# Start identifying what you can delete.  This is a wonderful opportunity to audit your home directory to see what really is in the directory called ''temp-567'' and what you actually put in the file ''subjects-az-list''.
# [[Tar Tutorial|Tar]] things up.  That is to say, take that huge collection of DICOM files and turn them into a single file to cut down on overhead (remember it is about both file count and file size on Hoffman2).  Unfamiliar with what tar is?  Check out the [[Tar Tutorial]]. -->
