Folks,
Got a question regarding perl code in cgi script.
I am running below line of code in cgi script which doesn't work as
expected.
my $ticket = qx{echo $p4pass | p4 login -p $p4user};
Basically command has to return a ticket or error message. I keep getting
$ticket as empty.
However, if I write same code in stand alone perl script, it works fine as
expected. Not sure what is going on.
I looked at other options like open(CMD, "| $cmd") and open3. But, not sure
how to get output from the command.
Any idea what is going wrong here.
Nothing in webserver logs too.
Thanks,
Craig.
I have no idea what p4 is, but perhaps you should make sure it's in the
path, e.g.;
print qx(which p4);
Also investigate the value of $?
Alternative ways to send the password to p4 would be to use Expect.pm or
IPC::Open3:
perldoc Expect
perldoc IPC::Open3
perldoc perlvar
