As you can see 'x' is a heck of a lot more than 'X'. It's my
fault, I should'a included a few cautions. First, you generally
only want to use 'kill' on specific applications that can't be
stopped more normally, not systems like X. Second, 'kill -9' is a
last resort, and should be used sparingly and carefully, and never
as root on your user owned apps. Much, much better to, as user run
'killall <app-name>' (see 'man killall').
If you need to stop X, use <Crtl+Alt+Backspace>

Was this after your 'kill -9 x'? Try running 'which ps' (and
also see 'man ps')

Not sure what you mean, but aliases are only modified commands
you already have on your system. alias wpid='ps aux | grep' put at
the end of the /etc/bashrc file just creates a command to run 'ps'
with aux switches and use it to search (grep) for the app-name you
supply after wpid . I use a lot of aliases to save typing or
needing to remember the syntax for long command lines. Probly be a
good idea to read the various Bash how-to's. Also do a Google on
'linux bash', there's many good tutorials on the Net.
