Re^2: Hiding/masking your username or password

If I remember correctly, not every OS supports assigning to argv[0] a.k.a. $0. Some OSes have limitations for assigning to it. See $0 in perlvar. Simply emptying @ARGV could also work on some OSes.

The best way is not to have passwords at all, but use public keys instead. Second best solution is to have passwords in a file readable only for the owner. Third best solution is to have passwords in configuration files.

You remember correctly, some SysV based systems won't let you change the process name. I can't remember if I encountered this on HP-UX or AIX but yeah. 1.13 How do I change the name of my program (as seen by `ps')?	[reply]

Just tried assigning to $0 and $^X on Win2000 with Strawberry Perl. Task Manager shows perl.exe in Processes whatever I try. So, it also does not work on Windows. Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply]
