History
|
|
|
|
|
=======
|
|
|
|
|
|
|
|
|
|
Sets [history][1] options and defines history aliases.
|
|
|
|
|
|
|
|
|
|
**Note:** Default path of `HISTFILE` has changed from `${ZDOTDIR:-$HOME}/.zhistory`
|
|
|
|
|
to `${ZDOTDIR:-$HOME}/.zsh_history`. The file will be automatically renamed if
|
|
|
|
|
possible (when the new one doesn't exist). Otherwise, if you want to preserve
|
|
|
|
|
previous history, you will need to move them from `${ZDOTDIR:-$HOME}/.zhistory`
|
|
|
|
|
to `${ZDOTDIR:-$HOME}/.zsh_history`.
|
|
|
|
|
|
|
|
|
|
Alternately, you can set `HISTFILE` manually to `${ZDOTDIR:-$HOME}/.zhistory`.

Options
|
|

|
|
|
|
|
`SHARE_HISTORY`, `INC_APPEND_HISTORY`, and `INC_APPEND_HISTORY_TIME` are
|
|
|
|
|
mutually exclusive.
|
|
|
|
|

|
|
|

|
|
|
|
|
- `HIST_IGNORE_ALL_DUPS` deletes an old recorded event if a new event is a duplicate.
|
|
|
|
|

|
|
|
