- # 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
- if ((BASH_VERSINFO[0] < 4))
- then
- echo "sensible.bash: Looks like you're running an older version of Bash."
- echo "sensible.bash: You need at least bash-4.0 or some options will not work correctly."
- echo "sensible.bash: Keep your software up-to-date!"

- ## 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"
