Scripting actions over tramp

Scripting actions over tramp

[Gary]

Maybe I should just try this, and am "worrying" over nothing, but I am
absolutely cream-crackered after being woken twice by alarms last night,
so my brain isn't working.

Is there a way to perform automated actions via tramp (or some other
method in emacs) on remote hosts?

Something like:

(tramp-ssh-connect some.host)
(tramp-exec "ls -la") ;; list directory contents on some.host
(tramp-disconnect some.host)

or something. I'm not bothered about having to type in username/password
combinations at this stage in order to login, more about executing some
commands on the remote host.

I'm also not interested in editing remote files in this scenario, what I
want is to be able to have the mode I am writing be able to interact
with the host to which I have just uploaded a script, say (that's not it
exactly but it's the easiest way to describe it).

(let ((default-directory "/ssh:user@some.host:"))
  (shell-command "ls -al"))

Best regards, Michael.

Thanks Michael. No wonder I couldn't find it - not only

  ^^^^^^^^^^^^^^ (bah!)
`----
but I also wasn't aware of the ability to use it like that, even though
I pretty regularly use it via M-!.

There seems to be a problem in your version of Emacs.  Please report it
as a bug.
