Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Make a statistic about the lines of code

Make a statistic about the lines of code

use find to grep all .c files from the target directory, cat them into one stream, then piped to wc to count the lines


There is 1 alternative - vote for the best!

find . -name \*.c | xargs wc -l | tail -1 | awk '{print $1}'

This is really fast :)

time find . -name \*.c | xargs wc -l | tail -1 | awk '{print $1}'

Have wc work on each file then add up the total with awk; get a 43% speed increase on RHEL over using "-exec cat|wc -l" and a 67% increase on my Ubuntu laptop (this is with 10MB of data in 767 files).

Know a better way?

If you can do better, submit your command here.

What others think

To ignore whitespace only lines in the count, use grep which can both search and count:

find . -type f -name "*.c" -exec cat {} + | grep -Evc '^[:space:]*$'

This will also be faster due changing \; to +.

Yeah, using + at the end of -exec is much faster than \;
