You are right with the killall command. On some UNIX systems where the
killall command is absent it becomes handy. The ssh via multiple hops will
not work also this is mainly used for telnet/ssh directly into a host. As
for the output of "who am i" across the various UNIX flavors that will also
vary, however the basic outline and functionality is still there. Its
really no big deal to go and change field separator and the variable to make
it work for your specific systems/flavors of Unix.

...just a note: ssh automatically redirects X data through an encrypted
channel back to the machine that ssh'd in and is smart enough to redirect
through multiple sites (if you got through three ssh'es the data will be
redirected through three encrypted channels). So you shouldn't use (or
need)
this one liner when using ssh.

... also 'who am i' prints out data in a different format on my machine:

so I wasn't able to play with that command...
