- While we're it, make "cmp" call the first character in a file 0.
- At least on my 4.2BSD system, cmp says the first character in a file is 1.
- I would imagine most people only use cmp to test for equality of files, but
- I had reason to use the output of "cmp -l" the other day in a shell script
- and got burned my this. Most likely, somebody needs to carefully go
- through every command in the book and ferret out count from 0/1 problems.
-
- Along those lines, what does it mean when some processor says
- "error in line 0, file foo"? On the one hand, it makes computer sense to
- call the "first" line/character/block/whatever of a file 0. On the other
- hand, it is very convienent to reserve "error in line 0" to mean "something
- went wrong before I even got a chance to start reading the file."
