Each Unix system has a directory /tmp which acts as a "scratch area" which you can use to hold files and directories for short periods of time. For example: mkdir /tmp/for_u_tim cp -r surprise /tmp/for_u_tim . This creates the directory for_u_tim in the directory /tmp and then copies the directory surprise to it. ... Do not use the /tmp directory to store vital information; it is cleared whenever the system is "booted up" and by the system administrator when the directory gets full. ...
