# Version: 0.2.2

|
||
## 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
|
||
|
||
|
||
# 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'

## 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"
