Re: ps with command line arguments

It's a security feature, since there are all kinds of things you can learn about other users if you are allowed to see the parameters they pass to their commands.

My "exec" workaround should work on FreeBSD :-) (however not tested on this OS yet) : "bash" process name will be replaced in ps output by the name given to exec with -a option, so perfect, that's enough !

The problem with procps.exe it that it relies on /proc/ : a user which do not have admin rights is not allowed to access Cygwin /proc/<pid>/cmdline, /proc/<pid>/stat etc... of other users (although on Linux for example it works)...
This bahavior leads to an incomplete / unreliable procps output.
