As you say, hd and hexdump _are_ the same program, programs get passed
the name that was used to execute them, so by symbolic linking the
executable to a different name you can get different behaviour. grep
/ fgrep / egrep are also the same program, you will no doubt find
quite a few more. Why waste disk space with multiple copies of nearly
identical programs if you can merge them?
