recursive wc on a directory?

Hi all,
I need to count the number of lines in all the files under a directory (several levels deep). I am feeling extremely dumb, but I don't know how to do that. Needless to say, I am not a shell script wiz... Any advice?

thanks in advance!

Try this:
Code:
find /topleveldirectory/ -type f -exec wc -l {} \;

Total Lines

Hi,

How do I get the total number of lines because when I try this command it just lists them endlessly where I only want one number?

Cheers

Code:
wc -l `find /dir/name -type f`

Note that those are backticks, and also be aware that if there are too many files you can exceed your shell's argument limitations.

this is an old thread.
beside exceeding shells argument limitations, you solution does not cater for files with white spaces.

Code:
find . -type f -print|while read FILENAME
do
      cat "${FILENAME}"
done | wc -l

Simple and fast:
Code:
find /topleveldirectory/ -type f -exec wc -l {} \; | awk '{total += $1} END{print total}'

No loops, no whitespace problems, no unnecessary cat
