daemonize
run commands as Unix daemons
TLDR
Run a command as a daemon
$ daemonize [command] [arguments]
Write PID to specified file$ daemonize -p [path/to/pidfile] [command] [arguments]
Use a lock file for single instance$ daemonize -l [path/to/lockfile] [command] [arguments]
Run as a specific user$ sudo daemonize -u [user] [command] [arguments]
SYNOPSIS
daemonize [options] command [arguments]
DESCRIPTION
daemonize runs a command as a Unix daemon. It handles the standard daemonization process: forking twice, creating a new session, changing to root directory, and closing standard file descriptors.
Useful for programs that don't daemonize themselves but need to run as background services.
PARAMETERS
-p pidfile
Write daemon PID to file-l lockfile
Use lock file for single instance-u user
Run as specified user-c directory
Change to directory before running-o file
Redirect stdout to file-e file
Redirect stderr to file
CAVEATS
The command must be specified with an absolute path. For modern systems, systemd services are often preferred. Lock files prevent multiple instances but require cleanup on crashes.
