+# Append history list to history file once the session exits, rather than replacing
+# the history file, erasing any past entries
+setopt APPEND_HISTORY
+
+# If the internal history needs to be trimmed to add the current command line, setting this
+# option will cause the oldest history event that has a duplicate to be lost before losing a
+# unique event from the list. You should be sure to set the value of HISTSIZE to a larger
+# number than SAVEHIST in order to give you some room for the duplicated events, otherwise
+# this option will behave just like HIST_IGNORE_ALL_DUPS once the history fills up with unique
+# events.
+setopt HIST_EXPIRE_DUPS_FIRST
+
+# When searching for history entries in the line editor, do not display duplicates of a line
+# previously found, even if the duplicates are not contiguous.
+setopt HIST_FIND_NO_DUPS
+
+# If a new command line being added to the history list duplicates an older one, the older
+# command is removed from the list (even if it is not the previous event).
+setopt HIST_IGNORE_ALL_DUPS
+
+# Remove command lines from the history list when the first character on the line is a space,
+# or when one of the expanded aliases contains a leading space. Only normal aliases (not
+# global or suffix aliases) have this behaviour. Note that the command lingers in the internal
+# history until the next command is entered before it vanishes, allowing you to briefly reuse
+# or edit the line. If you want to make it vanish right away without entering another command,
+# type a space and press return.
+setopt HIST_IGNORE_SPACE
+
+# When writing out the history file, older commands that duplicate newer ones are omitted.
+setopt HIST_SAVE_NO_DUPS
+
+# This option works like APPEND_HISTORY except that new history lines are added to the $HISTFILE
+# incrementally (as soon as they are entered), rather than waiting until the shell exits.
+setopt INC_APPEND_HISTORY
+
+# When using history expansion (such as with sudo !!), on enter, first show the expanded command
+# and only run it after confirmation (another enter press)
+setopt HIST_VERIFY
+
+# Remove superfluous blanks from each command line being added to the history list
+setopt HIST_REDUCE_BLANKS
+
+# When writing out the history file, by default zsh uses ad-hoc file locking to avoid known
+# problems with locking on some operating systems. With this option, locking is done by means
+# of the `fcntl` system call, where this method is available. This can improve performance on
+# recent operating systems, and is better at avoiding history corruption when files are stored
+# on NFS.
+setopt HIST_FCNTL_LOCK
+
+# Save each command's beginning time (unix timestamp) and the duration (in seconds) to the
+# history file.
+setopt EXTENDED_HISTORY
