perl -e 'my $a = qx[ll]; print $a;'
this didn't work for me. No output from the program

What is the program? Did you check $! for an error message?
my $output = qx[ll] or warn "couldn't run ll: $!";
print $output;
my $output = qx[ll] or warn "couldn't run ll: $!";
print $output;
does ll expect user input? probably replace by ls -la

The problem is that I'm using a old version of Perl (5.005_03 for sun4-solaris), in windows with a newer version all solucitons works.

$output = `command`; # one big string
@output = `command`; # list of lines
$output = qx[command]; # one big string
@output = qw[command]; # list of lines
You can also use open(), but the above should be sufficient.
