Hi again,,
Seems like you're stuck again. Okay, the problem here is the
">/dev/null". Notice the ">" sign over there. It's the shell
redirection metacharacter which causes "the shell" to pipe the output of
one script to a file. When you use "system" in list context, like you're
doing, you will not be able to use any shell metacharacters
"> < | & && ...". The output of the program will go to STDOUT
automatically--cannot be forwarded or piped. So, you have many possible
solutions:
1. Use the one-argument call to system just like you type your command
from the shell.
system "/dir1/dir2/prgname arg1 arg2 arg3 -p /tmp/kc >/dev/null";
2. Check if "progname" has an option to shut it up. "Usually -q"
If you're the one who wrote that program, then implement -q.
3. Use the backticks and throw away the output:
`/dir1/dir2/prgname arg1 arg2 arg3 -p /tmp/kc >/dev/null`;
But this is bad since poor perl will do its best collecting data that
you'll throw away anyways.
4. Probably there are 10 MWTDI.
Hope this helps,,,
