I want to use a combination of the date and time at startup as filename for GNU screen's logfile. In screenrc, if I put
I get a dynamically generated file, e.g.
Now I want screen to display this filename in the hardstatus bar. I cannot use
hardstatus string '~/log/screen_%H_%m%d%Y_%0c-%t.%n'
because the placeholders are updated whenever the time changes.
The solutions I can come up with involve a bash code executed before screen-startup but that's not good because the separate screen-windows are supposed to get their own dynamic logfile.
Is there a variable-substitution mechanism in screen?
