Automating execution of a command on remote machine with input file

Question

I need to automate the following workflow.

1. Copying a file (say inputfile.txt) to a remote machine (fixed ip) through SSH

2. Logging into that remote machine through SSH (using Remote Desktop Viewer of ubuntu)

3. Running a particular command with that file (inputfile.txt) as parameter.

   mycommand -option inputfile.txt
   

I need to be able to right click the file and choose "Execute my mycommand" context menu (Nautilus) item which will run the command in the remote machine. (and hopefully show a message box with the result - not that necessary)

Need suggestions on how to do it.

EDIT: Figured out copy works this way. Any idea on how to integrate into nautilus menu. Also the following command prompts for password

scp -r inputfile.txt user@machine.domain:/home/userremote/Documents

Answer 1

GUI-Programs aren't always easily automated.

The first challenge is the nautilus-script.
What does it contain?

cat ~/.gnome2/nautilus-scripts/mycommand

Maybe you can do it in a more direct way.

cat inputfile.txt | ssh REMOTE "mycommand"

or

cat inputfile.txt | ssh REMOTE "cat - > tmp.txt; ~/.gnome2/nautilus-scripts/mycommand -option tmp.txt"

or with two commands, scp first.
