Doesn't quite work on my vm (thought it kind of does):
mjhammel(tty0)$ perf
No command 'perf' found, did you mean:
 Command 'iperf' from package 'iperf' (universe)
 Command 'perl' from package 'perl-base' (main)
 Command 'gperf' from package 'gperf' (main)

Ubuntu can't just use "perf"?  Yet another difference.

On Fedora, which I know far better, I find that its pause to tell me
what package "bi" (instead of vi, for example) is in to be annoying.
I've been looking for a way to disable it.

Ahh!  That works.  Just redefine it to "return" and all is well.  Thanks
for the tip!
