Is there a way to get the shell (bourne) to remove temporary files that it creates from 'here is' documents? . We use shell scripts that use the form cat <<! ... and if the shell gets killed off (ie from autologoff routines, etc) files of the form /tmp/shxxxx are left floating around. Other then periodically cleaning up /tmp, is there a better way to get the shell to clean up its act?? Much thanx for any help.

For example, the bourne shell on UNIX System V/386 Release 3.2 Version 2.2 does not have this problem. In the short term, you could add this little front end to your here shell scripts ... sh <<! ls -l /tmp rm -rf /tmp/sh$$* ls -l /tmp exit ! As you see your /tmp/shxxxx file is gone. However, for your cat <<!, this won't work. Sincerely, John Urban
