Re: Get current window title in bash

[Neal Fultz]

I took a try at this, but didn't find any ideal solution.

Usually people set the window title from bash's prompt command, not the other way around.

There is an xterm escape code for "reporting a window title" that screen appears to support. There's a SO post that implies that it's usually disabled for security reasons.

The result comes back wrapped in escapes as well. 

Here's as far as I got:

nfultz@penguin:~$ read -p '^[[21t' -rs -d '\' A < $(tty)
nfultz@penguin:~$ echo ${A//[^[:alnum:] ]/}
lbash

Probably the best thing to do is write a small C program and use it...

Best,

Neal

My goal is to print the current window title in bash prompt. Currently I
know $WINDOW environment variable that contains the number of the

I learned about "screen -Q title" command but 2 problems emerged:

1. This command is slow and makes a delay when used in .bashrc.
2. When I tried this code:

if [ -n "$STY" ]; then
     TITLE=$(screen -Q title)
     PS1=$PS1"\[\033[01;93m\]$TITLE "
fi

It shows the title in the prompt and I have to click extra Enter key. Is
it possible to get the name quickly?
