Can "tput" be used to query what is currently displayed on a user's screen? My users all log into a 3rd party Point-Of-Sale program. I've written a script using "tput", which places a one word status message on a user's screen when certain conditions are met, like when they have unread mail. But, I don't want the message displayed unless they are in a particular menu. So, I need to able to evalaute what is currently displayed.

tput to query contents of user's screen?

I had the same problem a while ago.
I solved it by modifying the menu routine to create a zero-length lock file, the routine that did the tput checked for the presence of this file before trying to write to the users screen.
If you're not able to modify your menu program, another approach would be to check what processes are running for each user - you may be able to identify that the user is at the correct menu from that. Mike

I never could get the hang
of writing those things.
