bash-libraries

A collection of bash functions to accelerate simple DevOps scripting.

How to use

Add the following lines in the beginning of your script:

# Assuming that you have clone bash-libraries
BASH_LIBRARIES_PATH=<THE_PATH_WHERE_bash-libraries_ARE>
source $BASH_LIBRARIES_PATH/bash-libraries.sh

...

# your code continues here...

Note for OSX

In case you are using Mac OSX, make sure to brew install:

brew install gnu-sed --with-default-names
brew install coreutils

and add the following line to .bash_profile or .bashrc or whatever file you define your $PATH in order to use the GNU utlis with their original name and not prefixed with a g:

export PATH="$(brew --prefix coreutils)/libexec/gnubin:$PATH"

Modules

• bl::col (colors)
• bl::log (logger - to stdout by default)

bl::col

Note that shell colors description is not consistent across all platforms, so you better run $ ./bl_colors.sh test to check what suits your environment. Also, take care what colors you use, as in black backgrounds they might not look too highlighted. For RGB colors, there are extra shortcut functions.
