Temporary diskspace

Temporary diskspace is available on all Unix systems for working with large data sets. You may move your file into these directories while running jobs that need large scratch workspace. Files in these directories are erased periodically by the system manager.To move into these directories, at the system prompt, type:

        cd /tmp   a temporary directory cleaned daily  (roughly)

        cd /scr   a temporary directory cleaned weekly (roughly)

Keep in mind that there's no guarantee that files left in these directories will be there the next day. Never save data or output you want o keep in these locations for extended periods.
