Hi ,

How about find the total number of lines in a file ?
How can i do that with the "grep" command ?

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

You can use wc to find the number of lines.

wc -l < file.txt

grep -c "." file.txt

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

zsh 4.3.4% grep -c ^ file
3

Hmm.. 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.

i find it strange that after joining the forum for so long, you still don't know how to do that?

I suspect homework questions.

Hi ghostdog,

I think i know how to do it. See below!

wc -l myfile|awk '{print($1)}'`
