8.33: Is there a way to hide perl's command line from programs such as "ps"?

    First of all note that if you're doing this for security reasons (to
    avoid people seeing passwords, for example) then you should rewrite your
    program so that critical information is never given as an argument.
    Hiding the arguments won't make your program completely secure.

    To actually alter the visible command line, you can assign to the
    variable $0 as documented in perlvar. This won't work on all operating
    systems, though. Daemon programs like sendmail place their state there,
    as in:

            $0 = "orcus [accepting connections]";

The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
