Locking the keyboard during a script command

[kl522]

.
I have a simple script that does some useful housekeeping jobs;
however, it will hang up and require a re-command if any keyboard activity
occurs during the small time it takes to perform the housekeeping jobs.

Are there some simple commands that would allow me to lock-out
the keyboard just before and re-activate the keyboard just after
the script operations are in process?

Are you referring to locking the keyboard when you are running the script from a lxterminal ( or any other terminal emulators ) or you want to lock the entire keyboard and mouse for the entire X Window session ? If it is the formal you can consider using nohup and redirect input to null.

$ nohup command arg ..... < /dev/null

If it is the latter, I am not aware of a way to do it. In LXDE, locking is easy but automatically unlock is tough.
