Bash files

This is my bash files Project for Linux. It also works on Mac OS X with a few minor limitations. The project grew out of the tweaks and additions I applied for my personal use.

Some inspiration was taken from projects such as oh-my-zsh , bash-it and others.

Bash files is a work in progress project, everything is still a bit quick and dirty and constantly moving. I hope you enjoy it nevertheless.

Feel free to contribute, reuse, clone, etc.

Initial installation procedure

Clone the repository into your home directory, it will create the .bash_files subdirectory:

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

Invoke init file from .bash_profile

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

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

We put this in .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.

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

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

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