Sweet! My favorite bash history recipe (in .bash_profile, .bashrc, wherever …):

# remove duplicate entries from history …
export HISTCONTROL=erasedups

# keep a good size backlog …
export HISTSIZE=10000

# bind up and down arrow keys
bind ‘”\e[A”‘:history-search-backward
bind ‘”\e[B”‘:history-search-forward

# append history to .bash_history on shell exit, rather than overwriting
shopt -s histappend

With this, you can type the first few characters of anything in your history, then use the up and down arrow keys to search for the appropriate entry. Sweet!
