Linux commands: killall

A quick guide to the `killall` command, used to send signals to multiple processes currently running

Similar to the kill command, killall instead of sending a signal to a specific process id will send the signal to multiple processes at once.

This is the syntax:

killall <name>

where name is the name of a program. For example you can have multiple instances of the top program running, and killall top will terminate them all.

You can specify the signal, like with kill (and check the kill tutorial to read more about the specific kinds of signals we can send), for example:

killall -HUP top

This command works on Linux, macOS, WSL, and anywhere you have a UNIX environment
