您只需要找到完整的命令并复制具有别名的行即可。

我有别名d-m=“码头机”。d-m是docker-machine的别名。

所以在Mac上(通过brew)，补全文件在cd ' brew——prefix ' /etc/bash_completion.d/。 对于我的案例，我编辑了名为docker-machine的文件。 在最下面是:

complete -F _docker_machine docker-machine

所以我添加了另一行，用我的别名:

complete -F _docker_machine docker-machine
complete -F _docker_machine d-m

我也遇到了这个问题，并提出了这个代码片段。这将自动为您提供所有别名的补全。在声明所有(或任何)别名后运行它。

# wrap_alias takes three arguments:
# $1: The name of the alias
# $2: The command used in the alias
# $3: The arguments in the alias all in one string
# Generate a wrapper completion function (completer) for an alias
# based on the command and the given arguments, if there is a
# completer for the command, and set the wrapper as the completer for
# the alias.
function wrap_alias() {
  [[ "$#" == 3 ]] || return 1

  local alias_name="$1"
  local aliased_command="$2"
  local alias_arguments="$3"
  local num_alias_arguments=$(echo "$alias_arguments" | wc -w)

  # The completion currently being used for the aliased command.
  local completion=$(complete -p $aliased_command 2> /dev/null)

  # Only a completer based on a function can be wrapped so look for -F
  # in the current completion. This check will also catch commands
  # with no completer for which $completion will be empty.
  echo $completion | grep -q -- -F || return 0

  local namespace=alias_completion::

  # Extract the name of the completion function from a string that
  # looks like: something -F function_name something
  # First strip the beginning of the string up to the function name by
  # removing "* -F " from the front.
  local completion_function=${completion##* -F }
  # Then strip " *" from the end, leaving only the function name.
  completion_function=${completion_function%% *}

  # Try to prevent an infinite loop by not wrapping a function
  # generated by this function. This can happen when the user runs
  # this twice for an alias like ls='ls --color=auto' or alias l='ls'
  # and alias ls='l foo'
  [[ "${completion_function#$namespace}" != $completion_function ]] && return 0

  local wrapper_name="${namespace}${alias_name}"

  eval "
function ${wrapper_name}() {
  let COMP_CWORD+=$num_alias_arguments
  args=( \"${alias_arguments}\" )
  COMP_WORDS=( $aliased_command \${args[@]} \${COMP_WORDS[@]:1} )
  $completion_function
  }
"

  # To create the new completion we use the old one with two
  # replacements:
  # 1) Replace the function with the wrapper.
  local new_completion=${completion/-F * /-F $wrapper_name }
  # 2) Replace the command being completed with the alias.
  new_completion="${new_completion% *} $alias_name"

  eval "$new_completion"
}

# For each defined alias, extract the necessary elements and use them
# to call wrap_alias.
eval "$(alias -p | sed -e 's/alias \([^=][^=]*\)='\''\([^ ][^ ]*\) *\(.*\)'\''/wrap_alias \1 \2 '\''\3'\'' /')"

unset wrap_alias

您还可以尝试使用Git别名。例如，在我的~/。gitconfig文件，我有一个看起来像这样的部分:

[alias]
        co = checkout

所以你可以输入git com <TAB>，这应该扩展到git co master，这是git checkout命令。

Felipe Contreras对Git补全功能(参见Git 2.30中的Zsh补全)非常积极，他提出(可能是Git 2.31, Q1 2021)一个公共函数将有助于别名自动补全。

他的建议:

Back in 2012 I argued for the introduction of a helper that would allow users to specify aliases like: git_complete gf git_fetch Back then there was pushback because there was no clear guideline for public functions (git_complete vs _git_complete vs _GIT_complete), and some aliases didn't actually work. Fast-forward to 2020 and there's still no guideline for public functions, and those aliases still don't work (even though I sent the fixes). This has not prevented people from using this function that is clearly needed to setup custom aliases (this page), and in fact it's the recommended way. But it is cumbersome that the user must type: __git_complete gf _git_fetch Or worse: __git_complete gk __gitk_main 8 years is more than enough time to stop waiting for the perfect to come; let's define a public function (with the same name) that is actually user-friendly: __git_complete gf git_fetch __git_complete gk gitk While also maintaining backwards compatibility. The logic is: If $2 exists, use it directly If not, check if __$2_main exists If not, check if _$2 exists If not, fail

理想情况下，我想自动完成只是神奇地为我所有的别名工作。这可能吗?

是的，对于complete-alias项目(在Linux上)，这是可能的。对Mac的支持是实验性的，但用户已经报告成功。

首先，查找原始的补全命令。例子:

$ complete | grep git

complete -o bashdefault -o default -o nospace -F __git_wrap__git_main git

现在将这些添加到你的启动脚本(例如~/.bashrc):

# copy the original statement, but replace the last command (git) with your alias (g)
complete -o bashdefault -o default -o nospace -F __git_wrap__git_main g

# load dynamically loaded completion functions (may not be required)
_completion_loader git

可能不需要_completion_loader行。但是对于某些情况，补全函数只在您第一次键入命令并按下TAB之后才会动态加载。因此，如果你没有使用原始命令，并尝试alias + TAB，你可能会得到一个错误，如“bash: completion: function '_docker' not found”。
