如何使用bash脚本在远程主机上执行命令

execute_locally_then_remotely() {
    # Things I want to execute locally
    foo --bar
    foo --baz
    scp filename.gz $1:/tmp

    ssh $1
    # Execute these commands on remote host
    gunzip -xvf /tmp/filename.gz
    rm -f /tmp/filename.gz

    sudo -su otheruser
    # Bunch of other commands I'd like to execute as a different user on remote host
    foobar filename

    # Exit back to local shell and execute following commands here:
    ls
}

关于如何使用shell脚本实现所有这些,有什么想法吗?
