Zsh Options¶
We can use Z shell options to gain more control over the session. The following are a few of those.
setopt BANG_HIST # Treat the '!' character specially during expansion.
setopt INC_APPEND_HISTORY # Write to the history file immediately, not when the shell exits.
setopt SHARE_HISTORY # Share history between all sessions.
setopt HIST_EXPIRE_DUPS_FIRST # Expire duplicate entries first when trimming history.
setopt HIST_IGNORE_DUPS # Don't record an entry that was just recorded again.
setopt HIST_FIND_NO_DUPS # Do not display a line previously found.
setopt HIST_SAVE_NO_DUPS # Don't write duplicate entries in the history file.
