Description: I'm putting coding a perl program that needs to use system() a number of times. In a couple of the uses of system(), I need to, if possible, prevent a listing from appearing in the output of what shown if 'ps a' is run at the same time that the command in system() is running. Is there any way to do this in perl ? Answer: How do I prevent the command/parameters in a system call from displaying in ps
contributed by comatose No matter what, the command you are trying to
run is going to show up in the process list. ps
parses the /proc information and formats it nicely
and will show everything running no matter what you
might do in perl (assuming you don't use hacked
versions of ps and top).
The only way to keep command arguments from showing
is to use open() and pipe your arguments to it
through STDIN. There might be some potential for
obfuscation, but that's about it. |
