- Whether the optimization is worth putting in depends on how often
- people use wc -c, I guess.
-
- The unsharing process, among others, makes frequent use of `wc -c'.
- The `wc -c' usage which originated this thread was a `ddsplit' script
- (for a particular machine where I may not install GNU split) where I
- needed to know the overall size of a big file for computing the number
- of resulting pieces. It happened that the "size=`wc -c $input`" line
- was taking a fair amount of real time. Being curious, I just checked
- how GNU wc would behave on the same problem and discovered it was not
- as fast as I would have expected.
-
- I think GNU wc should be made faster, would it be only for the
- principle that GNU programs should do the best/proper thing in all
- circumstances :-).
-
- Keep all happy!
