Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Recursive Line Count

Terminal - Recursive Line Count
find ./ -not -type d | xargs wc -l | cut -c 1-8 | awk '{total += $1} END {print total}'

Recursive Line Count


There are 2 alternatives - vote for the best!

Terminal - Alternatives
find * -type f -not -name ".*" | xargs wc -l

Functions: find wc xargs

We use `-not -name ".*"` for the reason we must omit hidden files (which unnecessary). We can only show up total lines like this:

find * -type f -not -name ".*" | xargs wc -l | tail -1

Know a better way?

If you can do better, submit your command here.

What others think

Good command, although some parts are unecessary. :-)

Usage of 'cut' is superfluous, the $1 in the awk command will take the first (whitespace delimited) field on each line whether there are 1 or many fields per line.

Usage of xargs is good to do batch invocations, but you can have find do that for you as well (see the find manpage). So the command could be:

find ./ -not -type d -exec wc -l {} + | awk '{t+=$1} END {print t}'

Suggestion of improvement:

find * -type f -exec cat {} \;|wc -l

I really like sloccount for this...

Comment by xSmurf 425 weeks ago

Actually it prints the wrong answer, cause `wc` will prints total in the end, so the result will be doubly. Problem occurs in both commends belong:

find ./ -not -type d | xargs wc -l | cut -c 1-8 | awk '{total += $1} END {print total}' find ./ -not -type d -exec wc -l {} + | awk '{t+=$1} END {print t}'

And follow up command can done it right:

find * -type f -exec cat {} \;|wc -l

But we have a faster one:

find * -type f -not -name ".*" | wc -l

We use `-not -name ".*"` for the reason we must omit hidden filed (which unnecessary). We can only show up total lines like this:

find * -type f -not -name ".*" | wc -l | tail -1

Sorry, I just submitted wrong commends, the right one is:

find * -type f -not -name ".*" | xargs wc -l

The one show up total only:

find * -type f -not -name ".*" | xargs wc -l | tail -1

I had make sure they are correct this time. XDD
