Oh, Red Hat Enterprise Linux, where's my trusty killall command

So I'm about to rebuild a VM, and wanted to quickly kill off some Java processes: -

ps -elf|grep -i java

so I reached for my trusty killall command: -

killall java

but the computer said "No" : -

-bash: killall: command not found

so I tried to install it: -

yum install -y killall

Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
                                                                                                                                                                                                                            | 2.9 kB  00:00:00     
No package killall available.
Error: Nothing to do


Thankfully, this helped: -


which, although it was focused on Ubuntu, pointed out what I was missing: -

Hmm, instead of trying apt-get install, 

do an apt-cache search. 

On my FC15 box, killall is located in the "psmisc" package. 

But it sounds to me like something hasn't installed correctly. I would imagine killall would be installed by default on even the most stripped of distro's. Its been there the last time i installed Arch or a CentOS 6 netinst (which seemed to have a few things missing that i thought should be there)

so I tried that instead: -

yum install -y psmisc

Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
  Installing : psmisc-22.20-9.el7.x86_64                                                                                                                                                                                                                                  1/1

Complete!


and now I have killall : -

which killall

/bin/killall

and life is good again ( except for my Java processes, which have been killed )
