daemonize is a utility that allows you to run a command as a Unix daemon, which is a background process that is detached from the terminal and runs independently of the user’s session. It is useful for running long-running tasks or services that need to run continuously in the background.
To use daemonize, you will need to specify the command that you want to run as a daemon, as well as any necessary options or arguments. For example:
# daemonize command command_arguments
This will start the command as a daemon process. daemonize will fork the process and then exit, leaving the daemon process running in the background.
If you encounter the below error while running the command daemonize:
daemonize: command not found
you may try installing the below package as per your choice of distribution:
| Distribution | Command |
|---|---|
| Debian | apt-get install daemonize |
| Ubuntu | apt-get install daemonize |
| Kali Linux | apt-get install daemonize |
| Fedora | dnf install daemonize |
| OS X | brew install daemonize |
| Raspbian | apt-get install daemonize |
