Shell Programming and Scripting

Hi all,

Just like to ask if it is possible to do the following:

1. Have a shell script that calls ssh username@destinationhost
2. Upon successful verification, we ssh into the destination host and automatically use ksh to run a shell script that resides in the destination host. (Hopefully no further user input is required)

Thanks in advance.

Hi,
The man page says,

Code:

 ssh [-l login_name] [ hostname  |   user@hostname]   [  com-mand]

Example:

Code:

ssh user@dhost "~/bin/rndm.ksh"

Thanks

Before doing this there are some settings needs to be done, else you can only use interactive mode for entring password. If you need to incorporate the ssh in batch mode you have to have the keys create. See the help for ssh for more details.

It's alright to have ssh in interactive mode, though I'm running into some environment trouble after ssh-ing into the shell...

Seems like I'm getting the message "TERM environment variable not set" for all instances whereby I have to execute other scripts from the main shell. Can't seem to execute commands which spawns multiple pages like "more" as the program just seems to hang there. Commands like "clear" are not working either... is it happening because UNIX can't pinpoint what TERM is?

I've tried doing set TERM=xterm, but that didn't seem to work... any ideas on what's happening?

Thanks.

Alright, managed to fix the TERM environment bug...

Add the following as the 1st 3 lines of your script

#!/bin/ksh
TERM=xterm
export TERM

However, I'm still puzzled as to why the "more" command fails to work... often get an empty screen with no chance to exit the "more" command. So strange...

Quick tip on SSH.

Anything residing inside quotes " " after SSH xx@xx will be executes on the server, anything not in quotes will not be executed on that server.

Hmm... care to show some examples?

I'm using more in the command more "$rootdir/batchfile.log", so is this syntax correct within ssh, or must I add more quotes?
