$ make && make install && make clean

If you are root user, shelly will install to /usr/local/bin path giving you possibility to run the program from any directory.

To compile on macOS:

• install readline via Homebrew
• edit makefile or compile manually via terminal;

@if ! dpkg -l | grep libreadline-dev -c >> /dev/null; then apt-get install libreadline-dev; fi

@gcc main.c -lreadline -o shelly
