Equivalent/Alternatives for Alt+Dot in Mac

Question

One thing i miss from the Linux shell is the Alt+Dot shortcut. What it does is insert the last argument of the previous command. It appears to be a trivial technique, but it's really useful.

i.e. if you type this:

$ ls /Applications/MAMP/conf/apache/

The next time you just have to type a command + shortcut and the argument will be completed for you.

$ cd 'alt+dot'

On Mac i know 2 alternatives; pressing Esc+Dot or typing !$, !* with the magic space setup.

However while both alternatives do insert the last argument(s) you've used, they can't scroll back in command history like typing Alt+Dot repeatedly does.

I can live with this options for now, but i'd love to know if someone knows a better way to do it.

Solution 1

You can press Escape+. many times, it does the same thing as Alt+..
But, like you, I find it more cumbersome to type than Alt+..

Solution 2

In Terminal.app, Preferences->Settings, select the Keyboard tab. Ensure "Use Option Key as Meta" is checked.

Solution 3

Use option+.

Note that this is a feature of bash and not linux. Macs have bash on them as well. Alt-. is the shortcut for a builtin bash function insert-last-argument. Read the READLINE section of the bash man page for how you can bind this to a different key combination.

Pasting a few relevant parts:

   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.

Solution 4

If you open Terminal.app and enter preferences, and go to Settings > Keyboard and check “Use option as meta key”, you can use the bash shortcuts that use alt, for example:

Alt+B: Skip word backwards

Alt+F: Skip word forwards

Solution 5

If you're using iTerm2, do the following:

1. Select Preferences -> Profiles -> (select the currently active profile, or Default) -> Keys
2. Under the Key Mappings menu press the small '+' button
3. Click on Keyboard Shortcut
4. Press Option+. (or whatever other key combination you want to use as your Alt+Dot)
5. In Action select Send Hex Code
6. In the small text field that appears underneath type: 0x1b 0x2e
7. Press the OK button to create the new key mapping
8. Enjoy ;-)

I can press it many times, but it just works the first time

Thanks, i know is a bash feature but the shortcut is not enabled by default, at least not in Terminal.app since there's no meta key by default. See Richard's answer.

[pablasso]

btw, i should mention that while this solves the alt+dot problem, it messes up another keyboard combinations like ], } or |. My keyboard (spanish) uses option+somekey to type them. Well, you can't have it all.

[pablasso]

Nevermind, you're right. You just have to release esc to press it again, Then it works as expected scrolling through history. Being that treating the option key as meta messes up some other shortcuts, this is the cleanest solution.

Welcome to Super User! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. For now, I edited the answer for you.

For iTerm, open Preferences, Profiles > Keys, Choose option key acts as +Esc at the bottom.

[Johnny Ezzell]

The easiest way to do this is to check "Use Option Key as Meta" in Terminal preferences, as described in Richard Hoskins' answer.

[Nahshon paz]

yeah, who's using the default terminal these day? Thanks

For Terminal inside VSCode, set "terminal.integrated.macOptionIsMeta" to true.
