System commands

Hi,

I want to do some shell stuff with system().

echo jajajajaja|gpg --clearsign works
if I do it in the shell however if I try
to do it via PHP with the system() like:

$command = "echo jajajajaja|gpg --clearsign";
system($command, $output);
echo "$output";

I get an "2" as output. I don't have
a clue what's wrong. if I do the same
with $command = "ls";
Everything works fine.

Tnx!

First, stop quoting variables, it makes no sense.

Second, the manual says that system()
"Returns the last line of the command output on success, and FALSE on failure."

so whatever you do appears to print '2' as the last line.
