You are can add command alias to yours .bashrc file. echo "alias kbuild='fullpath/kbuild.sh'" >> "${HOME}/.bashrc". Replace fullpath with yours path to script.
After you are can start script with command kbuild --help.
For define default variables edit kbuild.sh file or copy code below to .kbuild file at yours home directory, vi "${HOME}/.kbuild", nano "${HOME}/.kbuild".
