Please dont hijack another thread. I am creating a new thread.

You can use wc to find the number of lines.
Code:
wc -l < file.txt

Using grep you can use

Code:
grep -c "." file.txt

Code:
zsh 4.3.4% cat file
a

b
zsh 4.3.4% wc -l file
3 file
zsh 4.3.4% grep -c . file
2

may be something like:

Code:
zsh 4.3.4% grep -c ^ file
3

and it's not bulletproof either ...

Hmm..Smilie my input file had empty lines or so I thought. It had the ^M characters which resulted into the same result for both wc and grep. Smilie
