History
|
|
|
|
|
=======
|
|
|
|
|
|
|
|
|
|
Sets [history][1] options and defines history aliases.
|
|
|
|
|
|
|
|
|
|
**Note:** If you are migrating from [Oh My Zsh][2] and are not on a recent
|
|
|
|
|
version of macOS and want to keep your history, you will either need to set
|
|
|
|
|
`HISTFILE` manually to `$HOME/.zsh_history` or rename `~/.zsh_history` to
|
|
|
|
|
`~/.zhistory`.

Options
|
|
|
|
|
-------
|
|
|
|
|
|
|
|
|
|
- `BANG_HIST` treats the **!** character specially during expansion.
|
|
|
|
|
- `EXTENDED_HISTORY` writes the history file in the *:start:elapsed;command* format.
|
|
|
|
|
- `SHARE_HISTORY` shares history between all sessions. Note that
|
|
|
|
|
`SHARE_HISTORY`, `INC_APPEND_HISTORY`, and `INC_APPEND_HISTORY_TIME` are
|
|
|
|
|
mutually exclusive.
|
|
|
|
|
- `HIST_EXPIRE_DUPS_FIRST` expires a duplicate event first when trimming history.
|
|
|
|
|
- `HIST_IGNORE_DUPS` does not record an event that was just recorded again.
|
|
|
|
|
- `HIST_IGNORE_ALL_DUPS` deletes an old recorded event if a new event is a duplicate.
|
|
|
|
|
- `HIST_FIND_NO_DUPS` does not display a previously found event.
|
|
|
|
|
- `HIST_IGNORE_SPACE` does not record an event starting with a space.
|
|
|
|
|
- `HIST_SAVE_NO_DUPS` does not write a duplicate event to the history file.
|
|
|
|
|
- `HIST_VERIFY` does not execute immediately upon history expansion.
|
|
|
|
|
- `HIST_BEEP` beeps when accessing non-existent history.
