The backtick operator is the most common way (be careful doing this for
commands that have a lot of output, because it all goes into a single
string).
my $result = `command arg1 arg2`;
You can also do this, if you have a lot of output to work through:
open(CMD, "command arg1 arg2 |") or die "Can't fork: $!\n";
while(CMD) {
next unless /PATTERN/;
# do other stuff
}
close CMD;
