Bash 和 Zsh 开启 vi-mode

bash 有两种操作模式，分别是 emacs 和 vi 。

在 bash 中

set -o vi # 临时开启 vi 模式
vi ~/.bashrc # 在其中写入 `set -o vi`
source ~/.bashrc # 刷新配置

在 zsh 中

vi ~/.zshr # 在 plugins 数组中添加 vi-mode
source ~/.bashrc # 刷新配置

    w            | 按词右移
    b            | 按词左移
    W            | 以空白字符按词右移(比如 ab a-b ， W 不会移动到 - 上，而 w 会)
    B            | 以空白字符按词左移
    e            | 移动光标到词尾部
    E            | 以空白符移动光标到词尾

    tc           | 右移到字符 c 的左边
    Tc           | 左移到字符 c 的右边
    ;            | 重做查找
    ,            | 反方向重做查找
    |            | 移到第 n 列 (如 3| 移到第 3 列)

  删除命令:
    x            | 删除当前光标所在字符.
    X            | 删除光标前的一个字符.
    d<mov. comm> | Delete text of a movement command <mov. comm> (see above).
    D            | 删除到行尾 (同 d$).
    dd           | 删除行 (同 0d$).
    CTRL-w       | 向左删除单词 (编辑模式下)
    CTRL-u       | 删除到进入编辑模式时光标位置

  撤销、重做、复制、粘贴:
    u            | 单步撤销
    U            | 撤销所有
    .            | 重做
    y<mov. comm> | Yank a movement into buffer (copy).
    yy           | Yank the whole line.
    p            | 在光标处粘贴
    P            | 在光标前粘贴

  历史记录:
    k            | 上一条命令
    j            | 下一条命令
    G            | 回来当前命令
    /string 或 CTRL-r  | 搜索历史命令(/string 用于命令模式下， ctrl-r 用于输入模式下)
    ?string 或 CTRL-s  | 搜索历史命令(Note that on most machines Ctrl-s STOPS the terminal | output, change it with `stty' (Ctrl-q to resume)).
    n            | 下一条历史匹配
    N            | 上一条历史匹配

  自动完成:
    TAB 或 = 或  | 列出所有可能(TAB 用于输入模式)
    CTRL-i       |
    *            | Insert all possible completions.

  其他:
    ~            | 切换当前光标处文本的大小写，并右移光标

```

== Emacs and Vi modes in Bash ==

Two options that can be set using the set command that will be of some interest to the common user are “-o vi” and “-o emacs”. As with all of the environment modifying commands these can be typed at the command prompt or inserted into the appropriate file mentioned above.

=== Emacs Mode ===

$ set -o emacs
This is usually the default editing mode when in the bash environment and means that you are able to use commands like those in Emacs (defined in the Readline library) to move the cursor, cut and paste text, or undo editing.
Commands to take advantage of bash’s Emacs Mode:
. o ctrl-a Move cursor to beginning of line
. o ctrl-e Move cursor to end of line
. o meta-b Move cursor back one word
. o meta-f Move cursor forward one word
. o ctrl-w Cut the last word
. o ctrl-u Cut everything before the cursor
. o ctrl-k Cut everything after the cursor
. o ctrl-y Paste the last thing to be cut
. o ctrl-_ Undo
. o NOTE: ctrl- = hold control, meta- = hold meta (where meta is usually the alt or escape key).
. o A combination of ctrl-u to cut the line combined with ctrl-y can be very helpful. If you are in middle of typing a command and need to return to the prompt to retrieve more information you can use ctrl-u to save what you have typed in and after you retrieve the needed information ctrl-y will recover what was cut.

=== Vi Mode ===
$ set -o vi
Vi mode allows for the use of vi like commands when at the bash prompt. When set to this mode initially you will be in insert mode (be able to type at the prompt unlike when you enter vi). Hitting the escape key takes you into command mode.
Commands to take advantage of bash’s Vi Mode:
. o h Move cursor left
. o l Move cursor right
. o A Move cursor to end of line and put in insert mode
. o 0 (zero) Move cursor to beginning of line (doesn’t put in insert mode)
. o i Put into insert mode at current position
. o a Put into insert mode after current position
. o dd Delete line (saved for pasting)
. o D Delete text after current cursor position (saved for pasting)
. o p Paste text that was deleted
. o j Move up through history commands
. o k Move down through history commands
. o u Undo
