Rsh Command 1

[Scunningham99]

have just created an executable file as a test to print out directory structure ie

!#/bin/ksh

ls -R /user01 lsi /simon.bat


---
This works fine but when the directory listing has finnished
the rsh command is still there doing nothing. i need it to quit out of the rsh on the server that kicked the rsh off!!!

This is only a test as in one of our backup scripts on server A at the bottom once it has finnished i am telling it to kick off a backup script on server b, which it does so fine, but does not quit out of the rsh, and subsequently left the rsh command running (idle) on server A.

Hi, another Cunningham on board!

Could you not just add an exit at the end of your script? I'm not too sure about rsh, but no doubt others will be able to advise whether this would work. HTH.

Thanks, but I have managed to figure this out by passing the paramater -n to rsh. ie rsh -n lsi /simon.bat. this sends the input to the spawned process to /dev/null, which solves the problem.

Thanks Anyway. Simon

I'm not sure what you mean ... here's what I did ...

- create this script on server B

#!/bin/ksh
ls -R /user01 lsi /simon.bat

- on server A, issue the command

rsh serverB scriptname


All appears to work fine for me. I would also note that I have server B defined in my .rhosts file on server A

Can you post the exact script you are running on server B?

Greg.

Grega,

Upon completion of script on Server b, When you do a ps -ef|grep on {script name } does it return PID and script name???

 

[grega]

No, no such processes running on either server. What happens if you log onto server B and run the script locally there? Does it run OK?

Greg.
