Be careful -- if you have an application say /usr/local/whatever/foo
that is linked from /usr/local/bin/bar then when you call
/usr/local/bin/bar it will populate bar as the argv[0] element.
This may be what you want, but then again, perhaps you want to know
that foo is the application being
Gak! The should was hedged with quotes because I couldn't verify
how it behaved. Apparently it's just a quick way to access argv[0].
Thanks!

Looking at /bin/head source code.
The usage function uses:
fputs(usage: head [-n line_count] [file ...]\n, stderr);
While many other programs use:
fprintf(stderr, usage: arch [-ks]\n);
Is there a difference? Is one preferred?
Yes, I know. I should take a C programming course.
