[BlueOnyx:05479] Re: need space

[Chuck Tetlow]

Sure,

Go into any directory (like the root / directory in your case) and use the command "du -hs *".  That gives you the "Disk Usage".  The "h" switch gives it to you in human readable (KB, MB, GB).  And the "s" switch causes it to summarize, so directories are given to you as one entry with its size.

If you've ever got a question about what's eating up your drive or partition space - go to the root of that partition and use that command.  Look for the oversized or ridiculously big directory, switch to it, and run the command again.  Sooner or later, it will lead you to the file or directory eating up your drive space.

This can also be a good command to run BEFORE you have problems.  Run it against your root directory and the directory that makes up each of your partitions (like /var /usr /home).  Run those commands when you first set up the box and have it completely operational - and store the results.  If you've ever got questions afterward, you can compare sizes of the new box with the current.  For example - if you haven't added software, or done significant updates - /usr shouldn't change appreciably.  There are a lot of "this directory should change under these conditions" and "that directory should never change" rules.  You've got to know how your box works and what its doing to recognize those - but it can be very helpful to know what those directory size values were in a new-condition box.  And it can help you troubleshoot problems, broken software, configurations, or even hacked servers.

Chuck

P.S. - Using that command can put a significant LOAD on the system.  Don't do it during peak/busy hours.  And for systems with large/full drives - expect to be waiting a while!
