how can i find number of lines in files & subdirectories

how can i find number of lines in files & subdirectories ?
# 2  
for a file:

Code:
wc -l filename

I'm presuming by "a directory" you mean "sum of lines for all files in a directory". If you don't want to include subdirectories:

Code:
cat dir/* | wc -l

If you do:
Code:
find dir -type f | xargs cat | wc -l

Code:
find . -type f -exec wc -l {} \;

You can get the summary lines for each file under current folder and subfolders.
