Guidelines for controlling your disk usage

• Remove core files. When your program exits abnormally, many times a memory image of your program is saved into a file called core. When this happens, you may see a message such as ``Segmentation Fault - core dumped''. A core file can be quite large (the size of all the memory alotted to your program). They can be useful for debugging, but remove them as soon as possible.

• Remove cache files. Your web browser's cache can take up logs of space. If you use Firefox, Select ``Tools'', ``Clear Private Data'', and make sure ``Cache'' is selected when you click ``Clear Private Data Now''.

• If you don't know what files are taking up your disk space, the command du displays the size of all of your directories and files. Large files can be seen using the CSL-written-and-supported program lff. You can type lff ~ to see a list of large files and directories in your home directory. Consult the manual page (type man lff) for more information.

• Remove executable files that you are not currently using. Executables can always be regenerated if you have the source code.

• If you are continually exceeding your quota, consider saving part or all of your directory to CD-ROM. Instructions are available on the web.
