My small script to create new simple C projects.

create.bash

#!/usr/bin/env bash

set -euo pipefail

if [[ $# -eq 0 ]]; then
  echo "Error: Please provide a project name." >&2
  echo "Usage: $0 <name>" >&2
  exit 1
fi

project_name="$1"

if [[ -e "${project_name}" ]]; then
  echo "Error: '${project_name}' already exists." >&2
  exit 1
fi

mkdir -p "${project_name}/src"

cat > "${project_name}/src/${project_name}.c" <<EOF

int main(void)
{
    printf("printonscreen!\n");
    return 0;
}
