Need Help??

in reply to executing commands and getting output

If you want to see the output of the text, your best option is the Pipe.
Ironicly i just asked rfp for some advice about his 'Pesky Pipe' problem so i can give you the example script and output:


[root@wicca /root]# cat ppipe.pl
#!/usr/bin/perl

open(FILE,"/bin/netstat|") || die("can't open");
while(<FILE>){
        print $_;
}
close(FILE);


[root@wicca /root]# perl ppipe.pl
