CMD Impacts

Problem description

Some Tru64 UNIX at command functionality does not exist on HP-UX.

The following at command features are supported on Tru64 UNIX and are not available on HP-UX:

  • DATEMASK environment variable.

  • -u user option to delete all jobs for the specified user. This option must be used in conjunction with the -r option.

  • -n [user] option to return the number of files in the queue for the current user. Root can specify a different user with the user argument.

  • -F option to suppress delete verification.

  • -c option to request that ksh be used for executing this job.

  • -i option to specify interactive delete.

  • -k option to request that ksh be used for executing this job.

  • -o option to list jobs in scheduled order. This option is useful only when used with the -l option.

  • -s option to request that the Bourne shell be used for executing this job (default).

The -l option behavior is different on Tru64 UNIX and HP-UX. On Tru64 UNIX, the root user can also request a report of scheduled jobs for the specified user only using the user argument. On HP-UX, the job-id must be used and not the user name.
