Hi,
thanks that works (with system() instead of backticks - for any reason I do not get dir output with backticks.
I tried it with the CMD I would use and it does not stop after 2 seconds.
use warnings;
use strict;
my $time = 2;
my $cmd = 'dir';
my $check = 1;
my $output;
print "check is $check\n";
eval {
local $SIG{ALRM} = sub { die 'timed out'; };
alarm $time;
my $cmd_1 = "perl hello.pl"; # see hello.pl code below"
open (CMD, "$cmd_1 2>&1|") or warn ("!!! Can't run program
+: $!\n");
while (my $line = <CMD>)
{
print $line;
}
close CMD;
sleep 4;
$check++;
alarm 0;
};
if ($@ && $@ =~ /timed out/){
print "damn command timed out!\n";
}
else {
print "$output\n";
}
print "check is now $check\n";
hello.pl
use strict;
use warnings;
$| = 1;
print "Hello World\n";
print "Sleeping 1000 seconds\n";
for (1 .. 1000) {
sleep 1;
print ".\n";
}
Any idea why this does not work?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
