daemonize 1.6.2-0

daemonize runs a command as a Unix daemon. As defined in W. Richard Stevens???*a*? 1990 book, UNIX Network Programming (Addison-Wesley, 1990), a daemon is "a process that executes ???*?in the background???*a*? (i.e., without an associated terminal or login shell) either waiting for some event to occur, or waiting to perform some specified task on a periodic basis." Upon startup, a typical daemon program will:<br /><br /> . Close all open file descriptors (especially standard input, standard output and standard error)<br /> . Change its working directory to the root filesystem, to ensure that it doesn???*a*?t tie up another filesystem and prevent it from being unmounted<br /> . Reset its umask value<br /> . Run in the background (i.e., fork)<br /> . Disassociate from its process group (usually a shell), to insulate itself from signals (such as HUP) sent to the process group<br /> . Ignore all terminal I/O signals<br /> . Disassociate from the control terminal (and take steps not to reacquire one)<br /> . Handle any SIGCLD signals
