Installation instructions

git clone https://github.com/binaryanomaly/bash_startscreen ~/.bash_startscreen

Invoke init file from .bash_profile

Add the following to the end of your .bash_profile in your home directory:

# .bash_startscreen initialization
if [ -f ~/.bash_startscreen/init.sh ]; then
    . ~/.bash_startscreen/init.sh
fi

# invoke .bashrc
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

We put this in .bash_profile and not .bashrc because we only want it to be executed when bash is executed i.e. a user is logging in - aka login shell. Therefore it may be necessary on Linux to enable an option such as "Run command as a login shell" so that the .bash_profile file is considered.

OS X

1. Install homebrew
2. Install coreutils brew install coreutils to use the more up to date linux coreutils

Dependencies

The following Standard Linux commands are needed:

• dig to determine the public ip via opendns
• free for ram info
• df for diskspace info
• last for last logins
• whatis for command related infos

Optional dependencies

The following optional packages are recommended to be installed:

• figlet for big ascii letter hostname
• lolcat to colorize the ascii letter hostname
• fortune-mod for fortune telling

Install them using apt (Linux) or homebrew (Mac)

The script will autodetect if each of those is installed and automatically disable the features if not found.
