bash

Set bash as our shell.

SHELL=/bin/bash

Without this we get a zsh warning.

export BASH_SILENCE_DEPRECATION_WARNING=1

Command prompt color settings

if [ "$PS1" ]; then
    export CLICOLOR=1
    export LSCOLORS=ExFxCxDxBxegedabagacad

    export PS1="\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\][\w]\[\e[0m\]: "
fi

The -G option is for colorized output.

alias rm='rm -i'
alias dir='ls -sG'
alias lss='ls -FsG'
alias l='ls -CFG'
alias la='ls -FAG'
alias ll='ls -FlG'
alias ls='ls -FG'

Path Overview

Shell commands are searched in order, so, to override os commands, put the local commands first, or, higher up in the list.

1. bin == binary
2. sbin == system binary
3. usr == non essential

This is in the default MacOS order:

export PATH=""
export PATH="$PATH/usr/local/bin:" # User supplied commands, listed first for override.
export PATH="$PATH/usr/bin:"       # Most user commands.
export PATH="$PATH/bin:"           # Essential before other file systems are mounted.
export PATH="$PATH/usr/sbin:"      # Non-essential System binaries.
export PATH="$PATH/sbin:"          # Essential System Binaries

Additional paths, temporarily commented.

export PATH="$PATH/usr/local/sbin:" # Locally installed system admin commands.

Setting PATH for Python 3.8

The original version is saved in .bash_profile.pysave

PATH="/Library/Frameworks/Python.framework/Versions/3.8/bin:${PATH}"
export PATH="$HOME/.poetry/bin:$PATH"
