[SOLVED]execute a command from terminal a into terminal b

[Mx11r3]

Hello there fellow compilers.

I want to make a script that reads a text file(device-config.cfg) of config lines and execute those lines in another terminal with a slight delay each line. Kinda like copy paste each line but automated...
The reason is because I am not able to paste 20000+ lines at once into the device via a ssh terminal.

I came up with this script but it only prints the line in the other terminal instead of executing it, at least it gives a good picture as to what i want:

I know 0 way to do that, in order to make them run, you must pass them not to the other terminal, but to the other shell of that terminal.

But you might take the problem from the wrong side maybe.
If you wish doing that i suppose it's because that terminal is running an ssh session and you wish all lines to be execute within that context.

I hope it will help you : ssh can run a command and disconnect. Something you can easy try with "ssh user@host ls ~"
This way you can have your goal met, read all lines of your file, and run "ssh user@host lines#"

The problem doing like that, is that you will have 20000 ssh connections/disconnections instead of your persistent ssh connection.
I tag this as a "problem" but ssh doesn't care, it's just to let you show the difference.

But doing that way, you will achieve your goal easy :
Here's pseudo code :
do read line
ssh user@host line
sleep slightdelay
until EOF

Hmm I don't think I can make that happen because the device (firewall/router) uses menu entrys which will be forgotten when ssh session ends.


I think i have an idea by using xclip. When I have time to figure that out i will post the results for anyone interested.

Are you looking for something like this?

Why won't you copy/paste those 2000 lines to file, prepend it with `#! /bin/bash` and execute the file?

You might try screen on the destination machine. I use a short routine to cause multiple host machines to "emerge sync" based on successful completion of a portage sync on a local portage tree server.

According to the OP, the destination is some stupid embedded device that offers a menu system over ssh, rather than a regular shell. As such, he probably cannot run screen/tmux on the device. It might be possible to force ssh to send the entire blob by using ssh device <file. Another choice is to use expect to interact with the menu system.

[cboldt]

Whatever is being interacted with, it was said to be at a /dev/pts, and I took that as being it was opened or viewed in a shell in a terminal.

Maybe all that's missing is a carriage return at the end of the line, in which case the cure might be as simple as appending \r or \n to the `echo -e $line` command line.

If the device can be opened in a shell in a terminal (on the local machine), that shell and terminal can be inside of a local instance of screen. That is, open screen, ssh to the device in one screen window, open another screen window (^A-c), and read/send from the second window, to the first.

Thank you all for thinking with me on this one and sorry for my late reply I was away on vacation.

It is indeed an embedded system, Fortigate and Cisco ASA to be exact.

I found a quick and dirty way to solve the issue. The shortest code for it, is this:
