Well... You could always setup your shell's prompt to contain
something like '<esc>k$tty<esc>\' and $tty be your tty name.
For example, I just added this to my .zshrc precmd() function:
PROMPT="k$(tty)\\%~> "
Voila, the title of a new screen window looks like "/dev/pts/3"
:)
You might want to play around a bit with this. In zsh, you could
try something like this:
function preexec {
# let's define a local variable
local y
# tricky: y is an array
# It is defined by using $1 and splitting it at ' ' (whitespace)
# Result: $y is an array that consists of all of the words of the command
line
y=(${(s: :)1})
# take the first element of that array and put it into the window title
# together with the tty name
echo -n "k$y[1] ($(tty))\\"
}
function precmd {
# just tell the user we're back to zsh ;-)
# together with the tty name
PROMPT="kzsh ($(tty))\\%~> "
}
Voila... you always see the currently running command name
together with the tty name. While one window title may look like
zsh (/dev/pts/13)
another one looks like
slrn (/dev/pts/14)
If you're not using zsh, you'd have to check your favorite
shell's possibilities... Perhaps you can come up with something
similar...
