~/.bashrc

If not running interactively, don't do anything

[[ $- != *i* ]] && return

Bash Completion

[ -r /usr/share/bash-completion/bash_completion ] && . /usr/share/bash-completion/bash_completion

Miniconda

[ -f /opt/miniconda3/etc/profile.d/conda.sh ] && source /opt/miniconda3/etc/profile.d/conda.sh

FZF

. /usr/share/fzf/completion.bash
. /usr/share/fzf/key-bindings.bash

Ignore case for auto-completion

bind "set completion-ignore-case on"
bind "set show-all-if-ambiguous on"

Use Color

use_color=true

Some config

# Unset some variables
unset use_color safe_term match_lhs sh

# Allow local processes with root privileges to connect to the locally running X server
xhost +local:root > /dev/null 2>&1

# Autocomplete sudo commands
complete -cf sudo

# Line wrap on window resize
shopt -s checkwinsize

# Enable history expansion with space
# E.g. typing !!<space> will replace the !! with your last command
bind Space:magic-space

# Expand Aliases
shopt -s expand_aliases

# Auto "cd" when entering just a path
shopt -s autocd

# Enable history appending instead of overwriting
shopt -s histappend

# Save multi-line commands as one command
shopt -s cmdhist

Prompt - PS1

export PS1="\[$(tput bold)\]\[$(tput setaf 1)\][\[$(tput setaf 3)\]\u\[$(tput setaf 2)\]@\[$(tput setaf 4)\]\h \[$(tput setaf 5)\]\W\[$(tput setaf 1)\]]\[$(tput setaf 7)\]\\$ \[$(tput sgr0)\]"

Rebind up and down arrow keys to search through bash history

bind '"\e[A": history-search-backward'
bind '"\e[B": history-search-forward'

Kitty for SSH

[ "$TERM" = "xterm-kitty" ] && alias ssh="kitty +kitten ssh"

Aliases

Better defaults for some commands

alias ls='ls -hN --color=auto --group-directories-first'
alias grep='grep --colour=auto'
alias cp="cp -i"     # confirm before overwriting something
alias df='df -h'     # human-readable sizes
alias free='free -m' # show sizes in MB
alias mutt="neomutt"

Change default configuration file location:

alias tmux='tmux -f $XDG_CONFIG_HOME/tmux/tmux.conf'
alias mbsync='mbsync -c $XDG_CONFIG_HOME/isync/mbsyncrc'

Neovim

command -v nvim >/dev/null && alias vim="nvim" vimdiff="nvim -d" # Use neovim for vim if present.

Print each PATH entry on a separate line

alias path='echo -e ${PATH//:/\\n}'

Functions

mkd - Create a new directory and enter it

function mkd() {
    mkdir -p "$@" && cd "$_";
}

Bash History

Undocumented feature which sets the size to "unlimited". http://stackoverflow.com/questions/9457233/unlimited-bash-history

# Huge history. Doesn't appear to slow things down, so why not?
HISTSIZE=500000
HISTFILESIZE=100000

# Avoid duplicate entries
HISTCONTROL="erasedups:ignoreboth"

# Don't record some commands
export HISTIGNORE="&:[ ]*:exit:ls:bg:fg:history:clear"

# Use standard ISO 8601 timestamp
# %F equivalent to %Y-%m-%d
# %T equivalent to %H:%M:%S (24-hours format)
HISTTIMEFORMAT='%F %T '

Change the file location because certain bash sessions truncate .bash_history file upon close. http://superuser.com/questions/575479/bash-history-truncated-to-500-lines-on-each-login

export HISTFILE=~/.bash_eternal_history

Force prompt to write history after every command. http://superuser.com/questions/20900/bash-history-loss
