A command to calculate lines of code in all tracked files in a Git repo

Count lines in Git repo

// Reference: http://stackoverflow.com/questions/4822471/count-number-of-lines-in-a-git-repository

$ git ls-files | xargs wc -l

omg thank you ❤️

I find this pretty useful (for public repos) https://codetabs.com/count-loc/count-loc-online.html

Plus there's an open API: https://api.codetabs.com/v1/loc?github=bluesky-social/social-app

An improvement based on what has already been said, by the way thanks for the tip.

Line counter for child folders with aggregator removing image files (webp|ttf|png|jpg|jpeg) :

How to use:

bash counter.sh foldername

counter.sh:

#!/bin/bash

# Root Folder
root_dir=$1

#  Count initialization
total_lines=0

# Loop
for folder in "$root_dir"/*; do
    # Check is folder
    if [ -d "$folder" ] && [ ! "$(basename "$folder")" = ".*" ] && [ -d "$folder/.git" ]; then
        # Run count command
        lines_in_folder=$(cd "$folder"; git ls-files | grep -vE '\.(webp|ttf|png|jpg|jpeg)$' | sed 's/.*/"&"/' |  xargs wc -l | grep -o "[0-9]* total" | awk '{SUM += $1} END {print SUM}')
        current_branch=$(cd "$folder"; git rev-parse --abbrev-ref HEAD)
        printf "%-80s -> %s lines\n" "$(basename "$folder") ($current_branch)" "$lines_in_folder"

        
        # Increment total lines
        total_lines=$((total_lines + lines_in_folder))
        
    fi
done

# Show total lines
echo "Total: $total_lines lines"

To only include the lines of code, can simply do

git ls-files "*.go" | xargs cat | grep -v '^\s*$' | grep -v '^\s*#' | wc -l

Just replace .go with your language's file extension. This excludes blank lines, configurations and comments so it presents an accurate number of actual lines of code.
