Can moderator take this thread to GNU ls/find and ask to provide option for counter. We all know that every admin uses counting of files into daily operation and into almost every script. It would be good value addition into those command lines.
Why a mod? The mods here aren't on the GNU committee AFAIK. In other words your suggestion has as much clout as theirs.
The best way to get what you want is to make your own modifications and submit a patch for them. You're far more likely to get what you want when you do the work.
Is this filesystem physically attached to the computer on which you are running the "find" ? If it is actually attached to another computer I'd run the "find" there.
Normally "find" is much faster than "ls" because "find" does not sort the output.
Also the simple ls command defaultly sort the ouput by name even when skipping aliases \ls
To avoid this you can use a special option -f (may depends on your plateform) this will force ls to display all found entries WITHOUT ordering them ... which can be ... MUCH FASTER in some case.
That is why when used with wc -l , and especially for direcory containing numerous entries, the ls command should be used with such "nosort" option

try this : ls -fR /users/home 2>/dev/null | wc -l

... or on any other PATH containing a bunch of entries

look how fast it can be : more than 23000 entries in less than a sec !
Code:
[ctsgnb@shell ~/sand]$ date && ls -fR /users/home 2>/dev/null | wc -l && date
Sat Mar 19 17:14:16 MDT 2011
23932

So I have a loop that stated if a directory exists or not. If it does it prints the number of files within that directory. I use this code...
result=`(ls -l . | egrep -c '^-')`
However, no matter which directory I input, it outputs the number "2"
What is wrong here? (4 Replies)
I am trying to display the output of ls and also print the number of characters in EVERY file name. This is what I have so far:

I've never toyed with awk, but it seems every time I present an elegant 2- to 8-line script, someone comes back with an awk 1-liner.

LINES=0

Some simple questions from a simple man.
If i wanted to count the number of files contained within a directory, say /tmp would ls -l /tmp ¦ wc -l suffice and will it be accurate?
second one: How would i check the number of files with a certain string in the filename, in the same directory.

I am trying to write a script that will look for a file in a directory, then remove it. I need it to loop until it has removed a certain number of files. Is it better to do a repeat or to list each file in a pattern? Files will be numbered like RAF.01.*, RAF.02.*, etc. Thanks, James (6 Replies)
