OK, so I want to start by first explaining my setup. I have a windows desktop at home, and I am SSH'ing into an Amazon EC2 instance (via PuTTY) running Amazon Linux. I have zsh as my default shell, and oh-my-zsh installed as well. This "cloud developer desktop" model works well for me, but I am having one problem that I have poured more time into than I care to admit: GNU screen only shows 'zsh' as the title of every tab. This is despite using oh-my-zsh's screen plugin (which I think isn't doing anything). Anyone able to help me out? I'd love to have something more descriptive in the tab, perhaps just the last x characters of the current directory (or an open file name if one is open in vim).

Like many screen users, I've had what I'm asking for before, but on a new rig now and don't fully understand everything in my .screenrc:

# Allow bold colors - necessary for some reason

attrcolor b ".I"



# Tell screen how to set colors. AB = background, AF=foreground

termcapinfo xterm "Co#256:AB=E[48;5;%dm:AF=E[38;5;%dm"



# Erase background with current bg color

# window numbering starts at 1 not 0

I also tried adding this to my .zshrc, and it helps, but isn't quite what I want, as if you run ls, now your title is ls. Ie, not very informative. But maybe editing here is actually the right way to go:

# So screen tabs receive running process title

# preexec () {

#   echo -ne "ek${1%% *}e\"

# }

Thanks in advance for your help!

Answering my own question a bit here:

Replacing the line in the preexec () function above with this helps:

echo -ne "ek$(pwd)e\"

Would still be best to only grab the characters from the x-to-last '/' to the end though, replacing the initial string with '...'
