ARM版homebrewでインストールしたaws cliのコマンド補完を有効にする方法

aws公式の手順が分かりづらかったのでまとめました。

環境

- M1 mac
- zsh
- ARM版homebrew
- aws cli v2

手順

1. aws_completerのパスを確認する。

$ which aws_completer

/opt/homebrew/bin/aws_completer

1. /usr/local/binにシンボリックリンクを作成する

    ```
$ cd /usr/local/bin
$ ln -s /opt/homebrew/bin/aws_completer

1. .zshrcに設定を追加する

$ vim ~/.zshrc

autoload bashcompinit && bashcompinit
autoload -Uz compinit && compinit
compinit
complete -C '/usr/local/bin/aws_completer' aws

1. 確認する

$ source ~/.zshrc
$ aws dynamodb [TAB]

batch-get-item describe-table-replica-auto-scaling scan
batch-write-item describe-time-to-live tag-resource
