in reply to How do I change my program's name under ps? ($0='abc' is messed up)

This is because when the process is created, the first argument is allocated to be the size of the actual process name. Try appending a \0 to your fake process name.

    \0 doesn't help on linux... On FreeBSD it seems to work with or without the \0 (in addition to displaying the original process name).

    If the memory is pre-allocated, then do I have to worry about overflowing it?

      Nope, you don't have to worry about overflowing it in Perl. You do however, when dealing with argv[0] in C, etc.
