Re: Re: Persistence of a window's title?

[Neal Fultz]

I googled your prompt command, it is probably your system default. This book lists it as a default in /etc/bashrc for fedora, for example:

https://books.google.com/books?id=0VRnDwAAQBAJ&pg=PA260&lpg=PA260&dq=printf+%5C033k%25s@%25s:%25s%5C033%5C%5C&source=bl&ots=yDkW0btNGw&sig=ACfU3U0JX62IdmvjkAxx1lMi6ExhfR3kuA&hl=en&sa=X&ved=2ahUKEwiAr5ei3sDpAhU8GDQIHYXYAv8Q6AEwAXoECAoQAQ#v=onepage&q=printf%20%5C033k%25s%40%25s%3A%25s%5C033%5C%5C&f=false

This person https://unix.stackexchange.com/a/163692/50441 says that it is the culprit and recommends "unset PROMPT_COMMAND", and there's a comment to also check $PS1.

Best,

Neal,

Thank you very much for your suggestions.  I looked at the links but I am still puzzled (although I know next to nothing about Xterm or "termcapinfo".)

Here is my PROMPT_COMMAND:

    $ echo $PROMPT_COMMAND
    printf "\033k%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/\~}"

I don't think that does any Xterm title resetting.

One other line in my "~/.screenrc" file that may be relevant is:

    term screen-256color

Any other pointers?

I would recommend checking your $PROMPT_COMMAND - some shell configurations reset the Xterm title, and screen can pick that up as a window title or pass it through depending on your environment.

Is a screen-window's title supposed to persist?

I have created two windows in one "screen" session.  I have titled them both by typing "CONTROL-a" followed by a colon followed by the word "title" followed by my title, one for each window.

I have the titles permanently displayed at the bottom of the window by two lines in my "~/.screenrc" file:

    hardstatus alwayslastline
    hardstatus string "%w"

I don't know if it makes any difference, but I also have

    altscreen on

The problem is that the screen-window titles do not persist.  After I enter a command like "ls", the title changes to something like

    username@machine:~/Man

where the directory name is the first first three characters of the name of the current directory in my home directory.

Is the lack of persistence working as designed, a bug, or am I missing something?

My version/release of "screen" on Fedora is 4.6.2-8.fc30.

Thanks for any help,
