[Expectperl-discuss] Problem running in bg

[Jason P. <jas...@su...>]

Hi,

I'm trying to run my perl code in the background under Solaris (tried 
under 5.6,7 and 9), but if I use Expect it hangs with "Suspended (tty 
output)".  I'm using perl 5.8.0.

Here's my test file:

#!/usr/bin/env perl

use Expect;

print STDERR "launching\n";
my $exp = Expect->new();
$exp->spawn("/sbin/sh");
print STDERR "launched\n";


% ./test.pl
launching
launched

% ./test.pl &
[3] 4179
% launching
[3]  + Suspended (tty output) ./test.pl

Any help would be greatly appreciated!

Thanks,
Jay Penney

You haven't said what you want to do and maybe
it doesn't matter.  But if you describe your goal there
might be a better path toward the goal.

Have you looked at "screen"? (ask google)

	Have you tried reading from the tty to see if that wakes sh up?
i.e.:

$exp->spawn("/sbin/sh");
$exp->expect(undef,'$ ');
print STDERR "launched\n";
