problem losing focus in terminal running rlogin

thelma_vance has asked for the wisdom of the Perl Monks concerning the following question:

Problem:

Step 1: rlogin to a remote server.
Step 2: enter the command "ksu - qrq" where qrq is not a supper user just a diffent user.

The script hangs because the script has lost focus.

Desired: After the "ksy - qrq" is executed then the the script executes "cd /cm/deliver/build; ls" returned information is a list of files.

Question: How should the script get focus after the "ksu - qrq" command.

Note: The server is a red hat 9 linux intell box.

Thanks in advance
Thelma

You want sudo, not a GUI su front end (presuming ksu is a KDE su thing). You can set it up so that it won't prompt for a password (or just setup ssh and allow whatever user you're coming from to run a script which returns the `ls`). Not that it has anything to do with perl . . .	[reply]

As Fletch has said, you need to use sudo instead of ksu to get it to prompt you in the same window. I'd just like to add that for that kind of conversation with remote servers, it would be appropriate if you used Expect - it has ways for you to match patters sent by the other server (like prompts) and send appropriate responses.

If your script is losing focus, you need to buy your script some glasses.	[reply]
