Unices avoid large directories to scalability problems like the one

None of the time comes from wc. Changing from ' | wc -l' to
'> /dev/null' creates no speedup at all.
ls's bottlenecks come almost entirely

sorry i was wrong about the -1
FILENAME_MAX is buffer size, not string length

no, actually gnu hurd was a proponent of unlimited paths

PATH_MAX is posix and should be defined in limits.h
FILENAME_MAX is

Also, there already is a constant for the maximum

isn't PATH_MAX a GNU extension?

It is the calculator I always use.

If you are going to release things to mailing lists (especially this
one), you are going to have to stop acting so personally offended

Thank you for your input Evan,
I've decided that renaming the file would probably only take one
command, and so I think another name might be possible to use.
Could we focus on the merit of the utility?
Thank you,

Fine,
I retract my statement.
The name still this has nothing to do with the utility of the
statement. Please focus the conversation on that.

Most of the time I have an HP-97 sitting on my desk. But when I don't, I use dc.

Are you serious? I use dc all the time. Just because you don't use it,
don't assume others don't. I find dc to be my calculator of choice.
I know there is a naming conflict, what does that have to do with the
usage of the program?
What was the last time you used the reverse polish notation calculator
that precedes the invention of C?
Thank you,

Hi guys,
I came up with a utility[0] that i think could be useful, and I sent
it to the moreutils page, but maybe it might fit better here. All it
does is give a count of files in a directory.
I was sick of ls | wc -l being so damned slow on large directories, so
I thought a more direct solution
