See the man pages for more information. If you have large files that you do not use regularly, it is a good idea to save them to a tape and then erase them from the hard disk. Tapes may be purchased from CCO, and our tape drive uses 4mm DAT tapes. 90m tape holds 4GB of data. Running Large Jobs Long running jobs should be run in the background and at a lower priority than regular jobs.
Machines run fastest when there is only one large job on the machine at one time.
For this reason, if you need to run more than one job, it is good practice to make a script file to run the jobs sequentially, instead of running them all at once. The first line of the script file must be exactly as shown above, and the subsequent lines are the commands you want to run sequentially.
