Perhaps he really wants to read and parse the output from the
command(s) instead of checking the status?
my $cmdline = "echo 'DIS CHS(*)' | runmqsc SQFR | grep CHANNEL | sort
| uniq -c";
# Open input pipe from command line.
open(my $pipe, "-|", $cmdline);
for my $line (<$pipe>)
{
# Parse columns from $line here.
# For example, let's just print them.
print $line;
}
close($pipe);
__END__
This is similar to piping the command to your program and reading from STDIN.
# Shell command.
$ echo foo | your_program
You can learn about the various modes of the open function with
`perldoc -f open'. Look for the MODE argument in relation to command
pipes.
