这个 `dirstack` 是根据 z.lua 的路径历史数据库计算的出来的,所以和具体的 shell 或者操作系统都没有关系。你退出再登陆不会丢失这些路径历史,不同的 shell 之间也可以共享同一份历史数据。

第一列数据代表该路径多少秒以前访问过,第二列是路径名称。此时,你可以试着敲几个字母,用 fzf 的字符串模糊匹配进行定位,或者用光标键的上和下(CTRL+J/K 也可以)来上下移动,最后按回车 cd 过去,或者 ESC 放弃。

- 1.5.11 (2019-03-02): fixed: os.path.isdir doesn't work for symbol link folders.
|
||||
- 1.5.10 (2019-03-01): Prevent writing file racing.
|
||||
- 1.5.9 (2019-02-25): `z -b` should not match current directory (close #56).
|
||||
- 1.5.8 (2019-02-21): new `$_ZL_FZF_HEIGHT` to control `--height` parameter in fzf.
|
||||
- 1.5.7 (2019-02-21): rename `$_ZL_FZF_SORT` to `$_ZL_INT_SORT` it will affect both `-i` and `-I`.
|
||||
- 1.5.6 (2019-02-20): set `$_ZL_FZF_SORT` to 1 to sort directories by alphabet in fzf.
|
||||
- 1.5.5 (2019-02-20): `$_ZL_FZF_FLAG` can be used to override fzf flags, default to "+s -e".
