Recommended installation procedure: $ git clone https://github.com/nk53/bash_utils_macos.git ~/bin $ ~/bin/setup_bash_profile.sh WARNING: This automatically adds the following to the end of your Bash profile: # ls colors export LSCOLORS=Exfxcxdxbxegedabagacad export CLICOLOR=1 # search ~/bin first export PATH=$HOME/bin:$PATH # shortcuts alias clc='clear; clear' alias cpy='clear; python' alias sl='ls' alias terme='$HOME/bin/term & exit' If you don't want these things in your bash profile (or you already have some of them), you should instead manually add only the parts that you want. The setup script `setup_bash_profile.sh` is meant to be used with a *fresh* bash profile.
