====== How to manage your disk space on the Grid ======
===== Caveat =====
For me, these commands only work on lxplus.
===== How much space do you use? =====
<code python>
SetupProject Dirac
lhcb-proxy-init
dirac-dms-storage-usage-summary /lhcb/user/<initial>/<username>
</code>
===== Getting a detailed list =====
<code python>
dirac-dms-user-lfns --help
</code>
will give you a detailed overview of all the options. Very useful are ''-m 3'', which will show all files older than 3 months, and ''--Wildcard="*.root"'', which will only show root files.

===== How big is / are my file(s) =====
Do
<code shell>
dirac-dms-data-size --Unit=MB myLFN
</code>
where myLFN can also be a list of LFNs.
