.bash

Handy bash shell aliases and functions that I've written/collected over the years.

These require bash version 4 or later.

How can I update my Mac OS bash to the newest version?

First thing, you need to install Homebrew:

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Then you can use Homebrew to install bash:

$ brew install bash

You must add /usr/local/bin/bash to the end of the /etc/shells file:

$ sudo vi /etc/shells

so it should look something like this:

# List of acceptable shells for chpass(1).
# Ftpd will not allow users to connect who are not using
# one of these shells.

/bin/bash
/bin/csh
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh
/usr/local/bin/bash

Then you need to change your preferred shell to the new bash:

$ chsh -s /usr/local/bin/bash <username>

Now, any newly opened terminals should use the new bash by default, you can verify by running:

$ bash --version

To Install .bash

Just clone this repository into some directory, and then source it in your .bash_aliases or .bash_profile file

source /path/to/repo/bash_profile.sh

Background color

If you have sourced navigation.sh and you drop a .bgcolor file in a directory with a format like this:

R G B

Where R, G, and B are integers between 1-255, then whenever you go into that directory, or a sub directory, the shell's background color will switch to the defined color. When you move out of that shell it will reset to whatever is defined in the environment variable BGCOLOR_DEFAULT.

You just have to add bgcolor_auto to your prompt:

export PROMPT_COMMAND="$PROMPT_COMMAND;bgcolor_auto"

TERM_TITLE

If you use bashenv.sh then you can override the default title of the term window using TERM_TITLE environment variable.
