How do I display the current “session” name or “sockname” of a screen session in the status bar?

Question

I run multiple screen sessions each created with \'screen -S name\' and I would like to be able to display in the status bar the name

Answer 1

In current versions of screen, there is a flag %S for the hardstatus line.

MWE (.screenrc):

hardstatus on
hardstatus alwayslastline
hardstatus string "%S"

This displays the session name without the ID (like ${STY#*.}).

(Same answer to other questions here and here for completeness).
