Number of files with *.something
I am trying to find the number of files that are of sas files. so I can do

find . -name '*.sas'

but I want to know how many. So what is the command to find so.

why do that?

use ls -ltr *.sas | wc -l

find is recursive, it will find them inside folders too if wished. You can tack wc -l onto it in the same way to get the number.

Thanks for the replies

ls -ltr -r *.sas | wc -l

only looks at the current location I think. I am trying to find something recursive like find where it will also look into the sub directories and include them to the count.

If you're going to throw away the pathnames, and if the only find implementations to be used support -printf, you can use that to emit nothing but a single newline character per file found. If there are a lot of files, it might speed things up a bit.

You can tack | wc -l onto the end of the find command as well, as already stated.

As an aside, the flags to ls serve no purpose here. And, a newline is a valid filename character. So, if any filename has one and since wc -l counts newlines, one might get wrong results.

Alister's solution (as always) is the most elegant:
Code:
find . -name '*.sas' -printf '\n'|wc -l
