How to truncate Directory lines in “wc -l” command?

Question

I am trying to get total number of lines in all of the files in the current working directory

in order to do this i tried this following command

wc -l * | tail -1

But this command also returns me the directories..

my output is like

wc: Folder1: Is a directory
wc: Folder2: Is a directory
wc: Folder3: Is a directory
1714 total

I want only the return number(1714 in this case) in the output. And then i will assign it into variable to use it later.

How can i truncate the directory lines?

Later on i may want to use this command with relative path... I don't know how to call wc -l command with relative directory parameter either?

Thanks..

Answer 1

You can use:

wc -l * 2>/dev/null

Better command would be using find to get only files:

OR else:

find . -maxdepth 1 -type f -print0 | xargs -0 -I % cat % | wc -l

OR else:

wc -l --files0-from=<(find . -maxdepth 1 -type f -print0) | awk 'END{print $1}'

Answer 2

find -mindepth 1 -maxdepth 1 -type f -exec cat {} ";" | wc -l
