The command "killall -l" in the Unix/Linux operating system is used to list all available signal names or numbers that can be used with the kill command.
In Unix/Linux, the kill command is used to send signals to running processes. Each signal has a specific purpose or action associated with it. The "-l" option with the killall command stands for "list," and it is used to display all the available signal names or numbers.
By running "killall -l", you will get a list of signal names or numbers like SIGHUP, SIGTERM, SIGKILL, SIGSTOP, etc. These signals can be used with the kill command to terminate or control the behavior of running processes.
