# History related options first and always, or else we risk screwing up

# this needs to be different from the default because
# default HISTFILESIZE is 500 and could clobber our history
HISTFILESIZE=
# max commands 1 session can append/read from history
HISTSIZE=1000000
# the time format display when doing the history command
# also, setting this makes the history file record time
# of each command as seconds from the epoch
HISTTIMEFORMAT="%Y-%m-%d %I:%M %p "
# consecutive duplicate lines dont go in history
HISTCONTROL=ignoredups
# This works in addition to HISTCONTROL to do more flexible things
# it could also do the same things as HISTCONTROL and thus replace it,
# but meh. dunno why, but just " *" does glob expansion, so use [ ] to avoid it.
