What do you mean "run it as hd"?

I don't see any mention of it the hexdump manpage, and I don't have an
"hd" in my path.  Some commands alter their behavior based on argv[0],
so I created an alias named "hd" that points to hexdump, but that
doesn't do anything any different than "hexdump":

$ which hexdump
/usr/bin/hexdump

$ ls -l $(which hd)
lrwxrwxrwx 1 grante users 16 Aug 19 21:00 /home/grante/bin/hd -> /usr/bin/hexdump

$ hd .bashrc | head -n2

0000010 7268 0a63 0a23 2023 6854 7369 6620 6c69

$ hexdump .bashrc | head -n2
0000000 2023 652f 6374 732f 656b 2f6c 622e 7361
