# Sensible Bash - An attempt at saner Bash defaults
# Maintainer: mrzool <http://mrzool.cc>
# Repository: https://github.com/mrzool/bash-sensible
# Version: 0.2.2
# Unique Bash version check

## GENERAL OPTIONS ##
# Prevent file overwrite on stdout redirection
# Use `>|` to force redirection to an existing file
set -o noclobber
# Update window size after every command
shopt -s checkwinsize
# Automatically trim long paths in the prompt (requires Bash 4.x)
PROMPT_DIRTRIM=2
# Enable history expansion with space
# E.g. typing !!<space> will replace the !! with your last command
bind Space:magic-space
# Turn on recursive globbing (enables ** to recurse all directories)
shopt -s globstar 2> /dev/null
# Case-insensitive globbing (used in pathname expansion)
shopt -s nocaseglob;
## SMARTER TAB-COMPLETION (Readline bindings) ##
# Perform file completion in a case insensitive fashion
bind "set completion-ignore-case on"
# Treat hyphens and underscores as equivalent
bind "set completion-map-case on"
# Display matches for ambiguous patterns at first tab press
bind "set show-all-if-ambiguous on"
# Immediately add a trailing slash when autocompleting symlinks to directories
bind "set mark-symlinked-directories on"
## SANE HISTORY DEFAULTS ##
# Append to the history file, don't overwrite it
shopt -s histappend
# Save multi-line commands as one command
shopt -s cmdhist
# Record each line as it gets issued
PROMPT_COMMAND='history -a'
# 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 '
# Enable incremental history search with up/down arrows (also Readline goodness)
# Learn more about this here: http://codeinthehole.com/writing/the-most-important-command-line-tip-incremental-history-searching-with-inputrc/
bind '"\e[A": history-search-backward'
bind '"\e[B": history-search-forward'
bind '"\e[C": forward-char'
bind '"\e[D": backward-char'
## BETTER DIRECTORY NAVIGATION ##
# Prepend cd to directory names automatically
shopt -s autocd 2> /dev/null
# Correct spelling errors during tab-completion
shopt -s dirspell 2> /dev/null
# Correct spelling errors in arguments supplied to cd
shopt -s cdspell 2> /dev/null
# This defines where cd looks for targets
# Add the directories you want to have fast access to, separated by colon
# Ex: CDPATH=".:~:~/projects" will look for targets in the current working directory, in home and in the ~/projects folder
CDPATH="."
# This allows you to bookmark your favorite places across the file system
# Define a variable containing a path and you will be able to cd into it regardless of the directory you're in
shopt -s cdable_vars
# Examples:
# export dotfiles="$HOME/dotfiles"
# export projects="$HOME/projects"
# export documents="$HOME/Documents"
# export dropbox="$HOME/Dropbox"
You can’t perform that action at this time.
