I'm looking to, all in the course of one batch file:

  1. ssh into a remote computer
  2. execute commands (per the batch file) on the remote host.

What options do I need to add to the ssh invocation so that the batch file executes the lines following the ssh invocation over the connection?

e.g., with sftp it's simply adding a -b /dev/stdin and then << EOF at the end; how do I do this with SSH?

You can just run

ssh machine_name < batch_file.sh

to run all commands in batch_file.sh on machine_name. Works with at least OpenSSH. If you want to enter those commands by yourself before opening ssh, you can use

ssh machine_name << EOF

Awesome---is there a way to throw literal commands through the pipe? –  invaliduser Feb 17 '11 at 20:14
    
Of course. You can use exactly same as with sftp; just write for example cat << EOF | ssh machine_name, write your commands and press ctrl+D (EOF) –  Olli Feb 17 '11 at 20:16

Here's a Useless Use of cat Award for you. (ssh < batch_file.sh and ssh <<EOF) –  grawity Feb 17 '11 at 21:55
