Just to be sure, is this really the request for some screen change or change in setup (and /etc/bashrc)? PROMPT_COMMAND for screen changed recently - it was definitely wrong, but the new behaviour seems to be not very accepted by some screen users. This change was requested by https://bugzilla.redhat.com/show_bug.cgi?id=969429 and discussion is there. If you have any proposal, how to improve it, feel free to suggest it - anyway the old escape sequence was imho wrong (it was cut&paste issue from xterm). Can I somehow force screen to ignore PROMPT_COMMAND? - GIlboa PROMPT_COMMAND will not be ignored, but you can easily set it yourself. If you have /etc/sysconfig/bash-prompt-screen with some content, it will be used instead of the default PROMPT_COMMAND in /etc/bashrc . If you set the PROMPT_COMMAND in ~/.bashrc yourself, it will have higher priority than the one from /etc/bashrc - so you can set it to the old one - PROMPT_COMMAND='printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' (which is wrong - and because of the invalid sequence, the screen ignored this PROMPT_COMMAND even though the effect was expected to be the same as in the case of xterm - so user@hostname:PWD ...
Actually, I tried setting up PROMPT_COMMAND in ~/.bashrc (TERM = "screen*") but it doesn't seem to last. However, at least as far as I can see, placing an empty /etc/sysconfig/bash-prompt-screen (+x) prevents screen from trashing the existing screen title and replacing it with PROMPT_COMMAND. - Gilboa So, for a long time people who wanted their screen window title to change had to change their ~/.bashrc for that (and by now they have that set up) and now it changes the default so everyone else needs to do something to restore it? Why? Case in point: I use screen for absolutely everything but bugzilla and I name each window with the BZ number I'm working on. Now I have to every machine I reserve in beaker to solve a problem to log in, make a change, log off, reset the window title to the bz number to log in again. This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Still an issue w/ F21.

Exactly my problem :( the only solution I see, and that would make both worlds happy, is to have screen be able to ignore PROMPT_COMMAND if requested.

I've long switched to tmux and I suggest you to do the same. Clearly making a couple of people happy with this PROMPT_COMMAND being default is more important. Contact me outside of bugzilla and I can help you make the switch too. This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '21'.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: The default bashrc file contains the lines if [ -e /etc/sysconfig/bash-prompt-screen ]; then PROMPT_COMMAND=/etc/sysconfig/bash-prompt-screen else PROMPT_COMMAND='printf "\033k%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' fi The PROMPT_COMMAND variable there indicates to screen that it should draw the title of the screen "window" dynamically. However, this seems to obliterate any title set by launching screen with the `-t` flag, which breaks certain scripts, such as devstack (and essentially removes the ability to set a title from the command line).
