この記事は公開されてから1年以上経過しています。情報が古い可能性がありますので、ご注意ください。

西澤です。みんな大好きAWS CLIに地味に嬉しいアップデートがあったのをたまたま見つけたのでご紹介したいと思います。

AWS CLIのリリース情報を確認していたところ、ちょっと気になる記述を見つけました。

1.13.0

feature:cli_history: Setting the value of cli_history to enabled in the shared config file enables the CLI to keep history of all commands ran.

feature:history list: Lists all of the commands that have been run via the stored history of the CLI.

feature:history show: Shows the important events related to running a command that was recorded in the CLI history.

きちんとマニュアルも更新されているようです。

history — AWS CLI 1.13.0 Command Reference

AWS CLIのhistory機能を有効化

前提として、AWS CLIのバージョンを1.13.0以上にバージョンアップしておく必要があります。必要に応じてバージョンアップしておきましょう。執筆時点の最新バージョンでは1.14.0になっていました。

$ aws --version
aws-cli/1.14.0 Python/2.7.10 Darwin/16.7.0 botocore/1.8.4

公式ドキュメントの手順の通りに設定を行います。cli_history enabledをプロファイルに設定すると、~/.aws/configファイルに設定が書き込まれるようです。

$ aws configure set cli_history enabled --profile cm-nishizawa
$ cat ~/.aws/config
[default]
output = json
[profile cm-nishizawa]
output = json
region = us-west-2
cli_history = enabled
:::

AWS CLIのhistory記録を呼び出し

それでは、この状態でhistoryがどのように呼び出せるのかを実際に試してみます。まずは、適当なawsコマンドをいくつか実行します。

$ aws ec2 describe-regions
$ aws ec2 describe-availability-zones
$ aws s3 ls s3://aaa

すると、.aws/cli/historyの下に何だかデータが生成されているようです。

$ ls -l ~/.aws/cli/history/
total 104
-rw-r--r-- 1 nishizawa.tetsunori staff 20480 11 30 11:21 history.db
-rw-r--r-- 1 nishizawa.tetsunori staff 32768 11 30 11:21 history.db-shm
-rw-r--r-- 1 nishizawa.tetsunori staff 0 11 30 11:21 history.db-wal
$ find ~/.aws/cli/history -ls -exec file {} \;

/Users/nishizawa.tetsunori/.aws/cli/history/history.db-wal: empty

まずは、実行したコマンドの一覧をlistで呼び出してみます。こちらはオプション等は一切無しのようです。

$ aws history list
b251d060-f43a-4124-8803-1b0307c4e292 2017-11-30 11:33:04 AM s3 ls 255

list — AWS CLI 1.13.0 Command Reference

それでは、実行結果の詳細をshowで確認してみます。これは想像していたよりずっとしっかりしたhistoryですね。驚きました。

$ aws history show

直近ではなく以前の結果をhistoryから取得したい場合には、listで確認したcommand_idを引数に渡せばOKです。
