List all aliases available in fish/bash shell

问题

Is there a way to list all aliases, something like:

$ ls-aliases
.. "cd .."
la "ls -Gla"
gs "git stash"
etc...

Also is it possible to add human readable descriptions to aliases ?

I'm on a MacOSX

回答1:

In bash:

To list all aliases:

alias

To add a comment, just put it at the end of the command, e.g.:

$ alias foo='echo bar #some description'

$ foo
bar

$ alias foo
alias foo='echo bar #some description'

Note that in fish the alias command creates a function using the alias name that wraps the alias value. So there isn't currently any way to list just "aliases". You can use the functions command to list the names of all the defined functions (which by definition includes aliases). If you want the names one per line just functions | cat.

You can add your own fish function to list aliases like so:

$ function aliases --description "list all fish aliases"          0|19:02:45
      for f in (functions)
          functions $f | grep \'alias
      end
  end

Then save it

$ funcsave aliases

And call it

$ aliases

Example output:

function fishc --description 'alias fishc=vim ~/.config/fish/config.fish' 
function flutter --description 'alias flutter=~/Repos/DevResources/flutter/bin/flutter' 
function imgcat --description 'alias imgcat=~/.iterm2/imgcat' 
function imgls --description 'alias imgls=~/.iterm2/imgls' 
function inkscape --description 'alias inkscape=/usr/local/Cellar/inkscape/0.92.2_1/bin/inkscape'

If someone stumbles upon this like I did:

Current fish version (3.0.2) has alias (without params) that lists all aliases.

(Similarly abbr lists all abbreviations.)

(@heemayl pointed out that bash has alias as well...)

Fish:

⏵ functions
abbr, ack, acs, alias, calc, cd…

⏵ functions ls
function ls
    command ls -A -x --si --color --classify --group-directories-first $argv;
end
