ssh_configの複数ホストにコマンド同時実行

More than 3 years have passed since last update.

Ansibleとかchefでもできますが、軽く設定できてssh_configの設定を使えるといいなと思って書きました。

こんな感じで使えます。

ssh-exec FILTER COMMANDS

ssh-exec ec2_site sudo apt-get update

.bash_rcに追記

ssh-exec () {
    local FILTER=$1
    shift
    local COMMAND=$@
    grep -r "^Host" ~/.ssh/* | awk '{print $2}' | grep $FILTER | xargs -P5 -I% ssh % $COMMAND
}

Bashで動作確認済みです。
