Subject: Feat(screen): Use `shelltitle` trick in `.screenrc`
X-Git-Url: https://git.phdru.name/?a=commitdiff_plain;h=9179da7b2b377a8bd9992e00ad90a071febadb51;p=dotfiles.git

Feat(screen): Use `shelltitle` trick in `.screenrc`

This was an experiment that only partially succeed:
In the simplest case `screen` changes the caption
to the name of the current program; but it doesn't see programs
that run deeper like programs started under `mc` or `vim`.
