Options

APPEND_HISTORY

When turned on, causes each zsh session, upon exiting, to append to the history file. (As opposed to writing to it.) This allows multiple paralell zsh sessions to share a common history file.

BANG_HIST

Enable history substitutions

EXTENDED_HISTORY

Save beginning and ending timestamps to the history file. The format of these timestamps is :%<beginning time%>:%<ending time%>:%<command%>

HIST_ALLOW_CLOBBER

Add `|' to all output redirections in the history. This allows history references to clobber files even when the CLOBBER option is unset.

HIST_BEEP

Beep when the user tries to referrence a history event that doesn't exist.

HIST_IGNORE_DUPS (-h)

Do not enter command lines into the history list if they are duplicates of the previous event.

HIST_IGNORE_SPACE (-g)

Do not enter command lines into the history list if any command on the line begins with a blank.

HIST_NO_FUNCTIONS

Do not store function definitions in the history list.

HIST_NO_STORE

Remove the history (fc -l) command from the history when invoked.

HIST_REDUCE_BLANKS

Remove superfluous blanks from each command line being added to the history list.

HIST_VERIFY

Whenever the user enters a line containing a history substitution, don't execute the line immediately. Instead, perform history substitution and reload the line into the editing buffer.
