How can I make a window "read only" in GNU Screen?

Question

I started a really long process and would like to check it occasionally how it goes, but want to avoid interrupt it by mistake. Is there a way to set only this window "read only" ?

Answer 1

The chacl command may be useful here: you need to remove write permission for all users at a window number N (0 in the example below):

<Ctrl-A>:chacl * -w 0<Enter>

where * means "for all connected users", -w for "remove write permission", 0 is the number of window being locked. To restore write permissions:

<Ctrl-A>:chacl * +w 0<Enter>
