Hi!
I am trying to write a perl code that will retry the
same command over
and over again until the return value is 0.
This is what I got for now:
#! /usr/bin/perl
use warnings;
use strict;
$command = 'ls -l';
if (system($command) == 0) {
}
elsif(system($command != 0)) {
print "Failed to execute: $command\n";
my $c++
}
I'm not shure to test it, because I don't know any unix
commands that
gives other than 0 in return
(I'm a n00b, but willing and trying to learn), could
anyone please
take a look and see if this is correct, and if not, help
me??
Tnx :)
