SSH来自shell脚本的另一个shell脚本

Question

I'm in host1 and I want to shell script shell1.sh to execute another shell script shell2.sh in another host machine host2 . Need to ssh for same. Sorry, I'm little new to this scripting

So:

host1$ sh shell1.sh ----ssh---->  host2$ shell2.sh

Answer 1

On your shell1.sh :

#!/bin/sh

ssh host2 '/bin/sh /path/to/shell2.sh'

And, if the shell2.sh file not on host2 :

#!/bin/sh

ssh host2 < /path/to/shell2.sh

On the first alternative, you are passing to ssh a second argument, that it interprets as being a command to execute on the remote machine.

From man ssh :

If command is specified, it is executed on the remote host instead of a login shell.

On the second script, the commands on shell2.sh are passed to the ssh command via stdin, which then forwards them to host2 's shell, finally executing them.

Answer 2

You can doing this :

local.sh :

#!/bin/bash
hostname
whoami
ifconfig

Then, with your local script, you can run it remotely :

ssh host < local.sh

The STDIN shell of the remote host will be connected with the local shell script.
