NAHW, that's easy:
ls|wc -l
Or I could, (couldn't I)
find . -type f|wc -l
There are other tricks, like:
du -a|wc -l
Etc, etc, etc...
There are also implications of depth, whether I want only files, and on, and
on, and on...
I'll keep it easy:
It is a directory that only contains files.
So, you'd say:
what's wrong with "ls|wc -l" ?
Well, here is the catch:
There are almost a million files in that directory.
And it gets worse:
This count has to be placed in a loop in a shell script to report a
second-to-second delta.
The truth is that find takes some 3 seconds to do the count.
What about ls without sorting?
That was almost 15 seconds.
Now, directories are files.
It would be great if I could "count lines" on that file or somehow
interrogate it "how many lines do you have?" without actually hitting the
filesystem for the count.
I'm considering writing a little C utility to do just that, but...
"struct stat" (my first shot) doesn't contain that information either.
Finally, the question is:
Is there a utility that would tell me QUICK a file count under a directory
(regardless of type)?
And if not, are there C/C++ system calls that would tell me that?
Thanks everyone! :)
