how to invoke external program and capture its output
Hi all,
I am using an external binary to view memory starting from a specific address and i want to automate this via PERL however there are problems. Hope you can help me ..thx
I have around 30K of addresses which i want to send each to the programme above and split & save in a seperate log file ..i firstly tried to verify that programme executes and run properly for just 1 address in the list, however i can`t see all the output ( see just 1 line) when i run the perl script below:
============================================================
Code:
#!/usr/bin/perl -w
open (FILE, 'addr.txt');
foreach my $line (<FILE>){
$command = `mem_disp $line 80`;
print "$command";
}
close (FILE);
=============================================================
This gives the following output:
Code:
bash-3.2$ split.pl
sh: line 1: 80: command not found
Opening RO Data Memory File scp.ro
Opening Memory File CP2.16.0000000c.18.pmd.raw

I think perl just cant see 80 in the command ..because the output is same as saying mem_disp <addr> without the number at the end..

This code is in my 'case' statement and it all else works fine.
The problem I have is that the value in 'procno' is not passed on to the external program (fireit).
It is passing all zeros instead of the actual process number.
