B-Menu
B-Menu is a minimalistic general purpose terminal menu written in C. It was designed to replace terminal-based login managers such as CDM. However, it can easily serve as a simple terminal menu for any situation where you would like to execute a command from a set of menu selections.
B-Menu has zero dependencies and it is intentionally feature-minimal. This keeps it easy to install, configure, and run.
Note that bmenu uses ANSI/VT100 terminal escape sequences to draw the menu in the terminal window. Most modern terminal programs support these sequences so this should not be an issue for most users. If yours does not, the menu may not render properly in your terminal window.

Download and Install
To install this project from source, you will need to have the tools git,
gcc, and make to download and build it. Install them from your package
manager if they are not already installed.
Once you have the necessary tools installed, follow these instructions:
git clone https://github.com/bartobri/bmenu.git
cd ./bmenu
make
sudo make install
This will build and install bmenu in to the /usr/local/bin directory.
Uninstall:
sudo make uninstall
Configuration
By default, b-menu looks for menu options in $HOME/.bmenu. This file should consist of one menu option and one command on each line, seperated by a colon.
Example:
Clear Screen:/usr/bin/clear
Dir Listing:/usr/bin/ls -l
Usage
Use the -c option to override the default menu file path:
bmenu -c /full/path/to/menu/file
Use the -t option to override the default menu prompt:
bmenu -t 'Choose an Option:'
Run as a Login Manager
To run b-menu when you login, place the following code in $HOME/.bash_profile:
if [[ "$(tty)" == '/dev/tty1' ]]; then
[[ -n "$BMENU_SPAWN" ]] && return
export BMENU_SPAWN=1
# Avoid executing bmenu when X11 has already been started.
[[ -z "$DISPLAY$SSH_TTY$(pgrep xinit)" ]] && exec bmenu
fi
If you do this, it is best to include a menu option to launch a shell. Add the following to your menu options file:
Shell:/bin/bash --login
