This is the script I use to create a basic C project fast. It creates the following files:

• A CMakeLists.txt file with a configuration.
• MIT LICENSE.md and README.md with the project name as a title.
• A .gitignore to ignore any folder called build.
• A simple hello world C file.
• A .clang-format file with the LINUX C style.

If you would like to use it, create a file with the following code (I named it c-init) and place it in you /bin folder. Make sure the folder is added to your PATH.

#!/bin/bash

if [ -z "$1" ]; then
        echo "Project name is missing."
        exit 1
fi

project_name=$1
project_dir=$(pwd)/$project_name

mkdir $project_dir
cd $project_dir

touch CMakeLists.txt
touch LICENSE.md
touch README.md
touch .gitignore

Usage

In my case is:
