Question

after a severe lightning strike nearby, a number of processes seem to be running on the server in runaway mode. which utility terminates these processes by name, and not just by process id number? answer endall down killall closeproc

Answer 1

On Unix-like operating systems, the killall command forcibly terminates processes, specified by name.

The  killall command

Any processes running any of the above instructions will receive a signal from killall. SIGTERM is transmitted if no signal name is supplied.

• Signals can be supplied by name (such as -HUP or -SIGHUP), number (such as -1), or option (such as -s).
• If the command name begins with a slash (/) and is not a regular expression (option -r), processes running that specific file are chosen for killing regardless of their name.
• killall returns a zero return code if at least one process was killed for each listed command, or no commands were listed and at least one process matched the -u and -Z search criteria. killall returns non-zero otherwise.
• A killall process never kills itself, but may kill other killall processes.

Syntax :

      killall [-Z, --context pattern] [-e, --exact] [-g, --process-group]

       [-i, --interactive] [-o, --older-than TIME] [-q, --quiet]

       [-r, --regexp] [-s, --signal signal] [-u, --user user]

       [-v, --verbose] [-w, --wait] [-y, --younger-than TIME]

       [-I, --ignore-case] [-V, --version] [--] name ...

The Kill and Killall Commands

The main distinction between the kill and killall commands is that the former terminates process cycles dependent on the Process ID number (PID), whilst the latter terminates running cycles dependent on the names and other attributes of the processes. Normal users can terminate or kill their own cycles (processes), but not those that share resources with other users; only the root client has the ability to terminate all cycles.
