Dir like command

This has to be the record for returned summary but when I got Mark Anderson's
reply, I think that one will be hard to top.

Mark Anderson:
This will print the total number of files (including subdirectories,
since they are files too) in the current directory:
% ls | wc -l
If you don't want subdirectories, then exclude them:
% ls -F | grep -v '\/$' | wc -l
or
% ls -l | egrep -v '^d|^t' | wc -l
or
% expr `ls -l | grep -v '^d' | wc -l` - 1
Just why these work is left as an excercise for the student. ;-)
If you want the number left-justified, pipe it through awk:
ls -F | grep -v '\/$' | wc -l | awk '{print $1}'
The last step is to create an alias or shell script that will take an
argument (call the script fnum):
#!/bin/sh
ls -F $* | grep -v '\/$' | wc -l | awk '{print $1}'
Use it like this:
% fnum /usr/local/bin
Dave McFerren:
try
ls | wc -w
This returns the number of files that are listed by the ls command. If you also
want hidden files, try
ls -a | wc -w
Mike Kail:
o simply show how many files there, use
% find . -type f -print | wc -l
Others where similar to Dave McFerren's
Continuing Thanks
