I am sorry but I confused the thing a little bit. Actually the process is a daemon started by squid to authentic the user. The squid sends the "username password" to daemon and daemon replies with OK or ERR. I wanted to test this daemon from bash prompt. It can be tested from a perl script with pipe/fifo.
