Bashrc stuff

This is my new bashrc:

export HISTFILESIZE=
export HISTSIZE=

PS1="[\u@\h \D{%Y-%b-%d %H:%M:%S}]\$ "

alias l='ls -alrtF --color=auto --group-directories-first'

alias ll='ls -CF --color=auto'

# The above alias for ls will show files and directories in order of modification time, listing directories first

My old bashrc:

# If not running interactively, don't do anything

case $- in

*i*) ;;

*) return;;

esac

# don't put duplicate lines or lines starting with space in the history.

# See bash(1) for more options

# append to the history file, don't overwrite it

shopt -s histappend

# update the values of LINES and COLUMNS.

shopt -s checkwinsize

# match all files and zero or more directories and subdirectories.

Also don't forget about inputrc:

# 1). Up arrow to auto-complete command from history: https://askubuntu.com/questions/59846/bash-history-search-partial-up-arrow

# Respect default shortcuts.

$include /etc/inputrc

## arrow up

"\e[A":history-search-backward

## arrow down

"\e[B":history-search-forward

After changing your ~/.inputrc you can apply changes using

bind -f ~/.inputrc
