sshでコマンド

ssh hoge1 fuga
でhoge1でfugaを実行できる．



応用して，以下をbashrcに書いておけば，

ssh_command_broadcast hoge 1 10 fuga
で一気にhoge1〜10でfugaを実行できる

function ssh_command_broadcast(){
    hostname=$1
    nodeid=$2
    endid=$3
    shift 3
    command=$*

    echo ""
    echo "*******************************************"
    echo "hostname=" ${hostname}`printf "%02d" ${nodeid}` "~" ${hostname}`printf "%02d" ${endid}`
    echo "command name=" $command
    echo "*******************************************"
    echo ""

    echo "Are you sure you want to continue ssh (yes/no)?"
    read ascert

    if [ $ascert = yes ]; then
        while [ $nodeid -le $endid ]; do
            echo ""
            echo ${hostname}`printf "%02d" ${nodeid}`
            ssh ${hostname}`printf "%02d" ${nodeid}` $command
            nodeid=$((nodeid+1))
        done
    fi
}
