Well you could easily do a loop, as well, if you wish to use killall. The same could be said for pkill. <br />
<br />
for i in user1 user2; do killall -u $i; done<br />

But will pkill kill all the users that are not exactly matched?<br />
<br />
Example:<br />
<br />
pkill -u john, mike;<br />
<br />
johnny processes will be killed as well?<br />
<br />

<div>
No, they won't.<br />
Neither pkill nor killall can do that.

Sorry, can't watch videos on my mobile.

Yep,<br />
<br />
except for the fact that you can't give killall a comma-separated list of userids with the -u flag.<br />

Ah, good point. &nbsp;I forgot that killall -u only takes a single user.

killall or pkill?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

The term 'shell' refers to a general class of text-based command interpreters most often associated with the UNIX and Linux operating systems. Popular shells include Bourne, Debian Almquist (dash), Korn (ksh), Bourne Again (bash) and the C shell family (csh). Some view the DOS 'cmd' prompt as a minimal shell of sorts. It is also possible to install Cygwin on Windows and emulate a full Unix environment with complete shell capabilities. Terminal emulators, such as xterm, GNOME Terminal and OS X Terminal, can be used to access shell.
