Top Forums Programming What is a daemon process? Post 16250 by Perderabo on Wednesday 27th of February 2002 09:49:09 AM

A daemon process has no controlling terminal. It cannot open /dev/tty. If you do a "ps -ef" and look at the tty field, all daemons will have a ? for the tty.

Most daemons tend to last a long time, be owned by root, and do something useful. But you really can't count on any of these thing being true.

The lack of a controlling terminal is the real defining characteristic.
