Mac中Alt + Dot的等效项/替代项

我从Linux shell中错过的一件事是Alt + Dot快捷方式。它的作用是插入上一个命令的最后一个参数。这似乎是一项琐碎的技术，但确实很有用。

即，如果您输入以下内容：

$ ls /Applications/MAMP/conf/apache/

下次您只需键入命令+快捷方式，参数将为您完成。

$ cd 'alt+dot'

在Mac上，我知道2种替代方法。按Esc + Dot或使用魔术空间设置输入！$，！*。

但是，尽管这两种选择都确实插入了您使用的最后一个参数，但是它们无法像重复键入Alt + Dot一样在命令历史记录中向后滚动。

我现在可以使用此选项，但是我很想知道是否有人知道更好的方法。

您可以按Esc点很多次，它执行的操作与Alt点相同。但是，像您一样，我发现键入要比alt点更麻烦。

在Terminal.app的“首选项”->“设置”中，选择“键盘”选项卡。确保选中“将选项密钥用作元”。

使用option+.

请注意，这是bash而非Linux的功能。Mac也受到打击。Alt- 是内置bash函数的快捷方式insert-last-argument。阅读bash手册页的READLINE部分，以了解如何将其绑定到其他按键组合。

粘贴一些相关的部分：

   Readline Initialization
       Readline  is customized by putting commands in an initialization file (the
       inputrc file).
       The  default key-bindings may be changed with an inputrc file.  Other pro-
       grams that use this library may add their own commands and bindings.

       For example, placing

              M-Control-u: universal-argument
       or
              C-Meta-u: universal-argument
       into the inputrc would make M-C-u execute  the  readline  command  univer-
       sal-argument.

   Readline Key Bindings
       The  syntax  for  controlling  key bindings in the inputrc file is simple.
       All that is required is the name of the command or the text of a macro and
       a  key  sequence to which it should be bound. The name may be specified in
       one of two ways: as a symbolic key name, possibly with Meta-  or  Control-
       prefixes, or as a key sequence.

       When using the form keyname:function-name or macro, keyname is the name of
       a key spelled out in English.  For example:

              Control-u: universal-argument
              Meta-Rubout: backward-kill-word
              Control-o: "> output"

       In the above example, C-u is bound  to  the  function  universal-argument,
       M-DEL is bound to the function backward-kill-word, and C-o is bound to run
       the macro expressed on the right hand side (that is, to  insert  the  text
       ``> output'' into the line).

       In  the  second form, "keyseq":function-name or macro, keyseq differs from
       keyname above in that strings denoting an entire key sequence may be spec-
       ified  by placing the sequence within double quotes.  Some GNU Emacs style
       key escapes can be used, as in the following  example,  but  the  symbolic
       character names are not recognized.

              "\C-u": universal-argument
              "\C-x\C-r": re-read-init-file
              "\e[11~": "Function Key 1"


   Commands for Manipulating the History
       insert-last-argument (M-., M-_)
              A synonym for yank-last-arg.

如果打开Terminal.app并输入首选项，然后转到“设置”>“键盘”并选中“将选项用作元键”，则可以使用使用alt的bash快捷方式，例如：

Alt+ B：向后跳过单词

Alt+ F：向前跳过单词
