PS1 prompt inserts text "777;preexec"

LinuxGeek46 · 12-08-2019, 07:59 AM

After an update to Fedora 31, not the most recent one, but an older one, I noticed the following anomaly in non-root screen sessions:

[dboth@david ~]$ echo "Hello world"
777;preexecHello world
[dboth@david ~]$

The extraneous 777;preexec text is insertet in PS1 by the /etc/profile.d/vte.sh script. Commenting out the last few lines, the “case” statement circumvents the problem.

There is a bug about this against tmux and I am wondering if tmux is part of screen.

Bug 1780785 on Red Hat's Bugzilla was created 12/06.

#case "$TERM" in
# xterm*|vte*)
# [ -n "$BASH_VERSION" ] && PROMPT_COMMAND="__vte_prompt_command" && PS0=$(printf "\u009D777;preexec\u009C")
# [ -n "$ZSH_VERSION" ] && precmd_functions+=(__vte_osc7)
# ;;
#esac

The problem appears to be in libvterm which is apparently used by both (assumption).
