How to calculate the number of lines in source code

Question

As the title says how i can calculate the total number of lines in a source code folder using bash commands

Answer 1

Use sloccount

Answer 2

You can just use

find . -name '*.php' | xargs wc -l

Answer 3

Use cloc. It supports about 80 languages.

Answer 4

You could try something like:

find . -name "*.java" -exec cat {} \; | wc -l

Answer 5

My suggestions would be

1. Use a find command as in Barti's answer to locate all the files
2. Use sed or something to strip out all the comments
3. Don't do it at all

SLOC is a very, very misleading way to measure software. Bill Gates said it was like estimating the quality of an aircraft by weight, and it may be the only helpful thing he ever said.

Answer 6

This will count empty lines as well, but it's easy. Go to the specific directory you wanna check and do

find . | wc

Answer 7

Already been answered, just giving another way using awk which you'll definitely have.

cat *.ext | awk 'BEGIN{i=0;} {i++;} END{print "Lines ", i}'

I only also suggest this because it can be easily edited to add patterns (such as comments) for lines that you don't want to count.
