critical impact:

last - command option differences (CrCh148)

Problem description

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

The -n option, which restricts the number of lines to display (SVID conformance), is supported on Tru64 UNIX but is not available on HP-UX. However, an alternative exists.

On Tru64 UNIX, the user's host name is displayed by default. On HP-UX, you must use an option to display the user's host name.

Solution description

Review your code and the applicable manpages to determine how to resolve this issue.

If your script uses the -n option, you can use the -number option. If your script relies on the last command returning the host name, add the -R option to your command line.
