.bash_aliases

##### ea - alias for editing aliases
#
#When setting up a new aliases file, or having creating a new file.. About every time after editing an aliases file, I source it. This alias makes editing alias a
#bit easier and they are useful right away. Note if the source failed, it will not echo "aliases sourced".
#
#Sub in gedit for your favorite editor, or alter for ksh, sh, etc.
#
alias ea='nano ~/.bash_aliases; source ~/.bash_aliases && source $HOME/.bash_aliases && echo "aliases sourced  --ok."'
#

##### Useful shell option #####
# Entering a directory name as a bare word will change into that directory
shopt -s autocd
# Automatically correct off-by-one typing mistakes when changing directories
shopt -s cdspell
# Make Bash wrap text properly if the terminal size changes
shopt -s checkwinsize
# Store multi-line commands in shell history as one-liners for easy editing
shopt -s cmdhist
# Correct off-by-one typing mistakes when tab-completing directories
shopt -s dirspell
# Allow aliases to be expanded even in non-interactive sessions
shopt -s expand_aliases
# Enable fancy globbing functions
shopt -s extglob
# Enable the recursive glob (**) function
shopt -s globstar
# Don't clobber other sessions' changes to global history when exiting
shopt -s histappend
# Don't try to complete on empty lines
shopt -s no_empty_cmd_completion
# Globs won't consider case
shopt -s nocaseglob
# Globs will consider hidden files, too
shopt -s dotglob
#Stop bash from caching duplicate lines.
