Wie ändere ich die Form, Farbe und Blinkrate des Cursors der Linux-Konsole?

GitHub Gist:So ändern Sie die Form, Farbe und Blinkrate des Cursors der Linux-Konsole

Ich definiere die folgenden Cursor-Formatierungseinstellungen in meinem .bashrc Datei (oder /etc/bashrc ):

##############
# pretty prompt and font colors
##############

Die meisten Apps verwenden die cnorm-Funktion, um den Cursor wieder in den "normalen" Zustand zu versetzen. Standardmäßig ist dies der blinkende Unterstrich. Aber Sie können dies in Ihrem Termininfo überschreiben. Dies sollte die meisten Anwendungen (vim, tmux usw.) reparieren. Setzen Sie diese Befehle ab:

infocmp -A /usr/share/terminfo linux > linux

Passen Sie den obigen Patch an Ihre Bedürfnisse an. Dies sollte ~/.terminfo/l/linux erstellen, das von den meisten Terminal-Apps abgeholt werden sollte.

Wenn Sie Bash verwenden, können Sie PROMPT_COMMAND verwenden, das nach jedem Befehl einen Befehl ausführt. Fügen Sie Folgendes in Ihre .bashrc

ein

PROMPT_COMMAND='echo -e "\e[?16;0;200c"'
