 In slave perl prog, there're some print codes.
However, when the master perl calling the slave one by system(command), the
slave perl print cannot be redirected to STDOUT. how to solve that?

What? That's what it already does by default.

Did you mean something like

system("perl my_other_program.pl > /dev/null") and die;

?

This makes STDOUT nothing to print, I guess?

When running the slave prog directly by perl slave.pl, something is printed
onto screen
but perl master.pl (master.pl call salve.pl by system) does not

On my system it does.
Maybe you should post a simple example of master.pl and slave.pl
showing when it doesn't.

Oh sorry the perl is called by a master SHELL master.sh but not master
perl...

#!/bin/sh
`perl slave.pl $dirname`

So how to solve?
