SIMULATION - Which signal is missing from the following command that is commonly used to instruct a daemon to reinitialize itself, including reading configuration files? killall -s _______ daemon
The signal that is missing from the following command that is commonly used to instruct a daemon to reinitialize itself, including reading configuration files, is 'HUP'.
The 'killall' command is used to send a signal to all processes with a specified name. The '-s' option specifies the signal to be sent.
To instruct a daemon to reinitialize itself, including reading configuration files, the 'HUP' signal is commonly used. The 'HUP' signal, or 'SIGHUP', is a request to hang up or terminate a process. It is often used to signal daemons to reinitialize themselves.
To send the 'HUP' signal to a daemon using the 'killall' command, you can use the following command:
killall -s HUP daemon
This command will send the 'HUP' signal to all processes with the name 'daemon', causing them to reinitialize themselves, including reading configuration files.
Note: Some daemons may not respond to the 'HUP' signal, or they may have different behavior when receiving the 'HUP' signal. It is important to consult the documentation for the specific daemon to understand how it handles the 'HUP' signal.
