Have you thought of hiding what you are doing on your linux bash shell prompt? and not allowing your colleague to see what command you are entering or do you want to confuse your colleague by showing something invisible but work as visible? then read out this…
Today I came across a neat, but pointless shell command. By running the following in shell, it will hide any commands you run.
root@server2 [/]# stty -echo
In order to disable this mode, simply remove the “-” before echo.
root@server2 [/]# stty echo
I guess there really is no point to the command, though you could always mess with your coworkers if they leave their shell prompt open
Cheers.

mysql_pconnect() will maintain a persistent connection to the database. Whenever your script calls the connect to database function, it first searches already existing connections to the database and if exists it will use the same connection to connect to the database, if not it will open a new connection to the database. ie. Connection is Persistent
where as mysql_connect() function will establish a new connection whenever a connection to database needed, and after executing the script, this function disconnects the connection. ie. connection is not a persistent one.
mysql_pconnect() function is used where your site has a Heavy Traffic and where as mysql_connect() function is used when there is moderate/less traffic to your site.
