'which' looks at your PATH environment variable - looking
for the file name you gave it as a parameter.... as in,
"If I were to execute this command, 'which' file would it run?"
Also - looking at /proc isn't portable - different UNIXes uses
different /proc structures (some don't have it at all..)
But, that may not matter in the "modern era".
