We’ll be looking at how to install the Linux command killall in this article.
Killall send’s a signal to, if not explicitly specified, terminate all the processes with the given name.
CentOS used to ship with killall out of the box but since version 7 it’s been left out.
[root@test2 root]# which killall /usr/bin/which: no killall in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)
To install, issue the following command at the terminal:
yum install psmisc
To install killall on Ubuntu
sudo apt-get install psmisc
