I'm pretty new to LINUX. I'm trying to set up some users that will be accessing my Red Hat 6.1 server from Windows PC's using a terminal emulator. I would like to execute a program as soon as they log in as this is the only program these users will be using on this server. Is there a .profile or something similar I can edit to add this command line to it? If so, where and how?

Thanks!

are the users logging into a terminal or into gnome or someother window manager?

They're logging into the server as though they're runnig a terminal. It's coming in at the command prompt. I've done something similar in SCO UNIX some years back, but I'm not sure that would apply here. In UNIX, there was a .profile for each user and you would edit that to change path info or to execute say a menu script... That's essentially what I'm looking to accomplish. I don't want the user to ever have to see teh command prompt.

Thanks for your help!

"A startup program for every user

There's a startup program for eash user, too. In the bash shell, modify the user's ~/.bashrc file. (Note that tcsh uses the ~/.tcshrc file.) You'd most commonly use these files to add command line aliases, modify prompts, and the like, but any shell command can be placed there. "

That's probably what you want. Just put in the command to launch the app, and when they login, it should automatically go. The link at the top provides some additional ways that may be helpful to you.
