I set the terminal title according to my current command line, which sometimes include newline in it. In konsole, I always get several annoy blank lines with multi-line command (for loops etc.). The problem turns out to be the newline's (not any other characters) in the terminal title I set got unexpectedly echo back to the terminal. This doesn't happen in vte{2,3}, xterm, so should be a bug of konsole. Reproducible: Always Steps to Reproduce: 1. run command `env echo -e 'j\e]2;\n\aj'` in konsole (use `env echo` to avoid any shell-specific features of builtin echo's.) 2. 3. Actual Results: print "jj" Expected Results: print "j j"
Oh I flipped the expected and actual result................ SHOULD BE: Actual Results: print "j j" Expected Results: print "jj"
Anything between the \e]2; and the \a (007) should not be outputted to the screen.
I think this bug has already been resolved as I am getting Expected Results!

Git commit d547d1d177bd0582df95a5d50dc3b37e0636748e by Kurt Hindenburg, on behalf of Ahmad Samir. Committed on 24/05/2018 at 12:34. Pushed by hindenburg into branch 'master'. Ignore control characters in the text part of Xpe "ESC]" sequences Summary: Ignore control characters in the text part of Xpe (OSC, Operating System Control) of the form "ESC]Pn;Pt\a" escape sequences; this matches what XTerm docs say. If userTitle is an empty string, set the window title to a blank space when showWindowTitleOnTitleBar is enabled; basically if the user sets the title to an empty string, leave it as-is. FIXED-IN: 18.08 Test Plan: - unset PROMPT_COMMAND, in case the shell is configured to set the window title via that variable - Make sure "Show window title on the title bar" is enabled - Execute: $ /usr/bin/echo -e 'j\e]2;\n\aj' - The window title is changed to the tab title text; and the output looks like this: j j - Apply the diff, build, and try again, the window title should be set to an empty string (really a blank space), and the output should look like: jj Reviewers: #konsole, hindenburg Reviewed By: #konsole, hindenburg Subscribers: konsole-devel, #konsole Tags: #konsole Differential Revision: https://phabricator.kde.org/D13078 M +6 -3 src/MainWindow.cpp M +6 -0 src/Vt102Emulation.cpp https://commits.kde.org/konsole/d547d1d177bd0582df95a5d50dc3b37e0636748e
