Exiting the Remote server after script execution

Shell Programming and Scripting
1

Hi All ,

I'm running a script abc.sh in server "host1" shown as below :


#! /bin/bash

sh stop.sh

ssh user@$host2 "/home/user/prod_work/xyz.sh; 

sh start.sh

The problem I am facing is , the control is not passed to host1 after executing the script "xyz.sh" in host2 .

How to exit the session in host2 after executing the script xyz.sh ??

Thanks,
Pradeep

is working ?

"/home/user/prod_work/xyz.sh;

There's either one double quote too many or one too few... anyhow, the shell should complain.

4

Sorry..I actually pasted the code wrong ..It is

ssh user@$host2 "/home/user/prod_work/xyz.sh"

But even then the issue remains .

  • what about contents of your script ?
# cat /home/user/prod_work/xyz.sh
  • your ssh connection passwordless ?

What do you mean by 'return control'? What do you expect to happen? What happens?

Yes , the ssh connection is passwordless . I achieved that using the below :

SSH login without password

When I execute abc.sh in server "host1" , the shell script is executed till

ssh user@$host2 "/home/user/prod_work/xyz.sh" , but hangs after that . It does not continue to execute the next line (sh start.sh ) in host1 until I press Ctrl+C . That is what I mean by returning control .

Thanks,

Is there any reason why you don't want to show the content of /home/user/prod_work/xyz.sh as ygemici asked in post # 5?

9

Yes . Sorry... I'm not in a position to show the script for security reasons but it is a simple script only and it is successfully executed nevertheless .

Thanks,

That's fine, I was wondering because that would had helped. No worries.
It appears that the content of the script is at fault.

Forgive me if this question sounds very simple.
Have you tried with another script, perhaps with just a ls or echoing something?

Hi Aia ,

Thanks for the replies . I have got it working by directing the script to /dev/null (solution got from unix.com forum ).


ssh user@$host2 "/home/user/prod_work/xyz.sh > /dev/null"

But , not sure about the logic though .

Thanks,

It might be better to redirect /home/user/prod_work/xyz.sh to /dev/null, to fix it on the remote side, instead of the local side. Less round-trip, and saves you one stream if you ever need it later.

Thanks . Will try the same .
