Interesting that of all the commands mentioned, ar is (at least for me) no longer used (although I haven't used ed in many years). As I recall it, ar was mostly of use to address the extremely low limits on inodes and disk space: the former by packing a bunch of files/inodes into a single file, the latter by saving the wasted space on any file that wasn't a multiple of 512 bytes. I guess it lives on in the creation of "libraries" that could be loaded by compilers, although I think shared objects have largely replaced archive files, and I'm not sure if archive files are even accepted any more.

I always spelled out the two-letter commands: e-d, a-r, l-s, r-m, c-p.
chmod I pronounced as ch-mod (not mode), but 'rmdir' was 'remove dir'
and for some reason, mv was move. (I think the doc for vi officially
stated that the proram's name was to be pronounced v-i and not 'vie'.)

Undoubtedly there were many regional differences... :-)
