How to dynamically change xfce4-terminal title to the current host ?

Hi,

I use xfce-terminal 0.8.9.1

Is there a way to achieve this ?

Thanks

Re: How to dynamically change xfce4-terminal title to the current host ?

What do you mean by "dynamically change"?

If you are referring to the setting within terminal preferences, see https://docs.xfce.org/apps/xfce4-terminal/4.16/usage.

If you mean something like changing the terminal title to match the host of say a remote ssh connection, then each remote account that you connect to will need to have a similar PROMPT_COMMAND. For example:

PROMPT_COMMAND='printf "\033]0;host: %s\007" "${HOSTNAME%%.*}"'

Within xfce4-terminal settings, make sure you have dynamically set title enabled.

Re: How to dynamically change xfce4-terminal title to the current host ?

Thanks, the later is what I meant.

But can I keep my old PS1 too ?

Because I already have a hudge script to feed PROMPT_COMMAND:

[[ -t 0 ]] && stty -ctlecho # eviter ^C affiché dans le term

PURPLE=$(tput setaf 5)
RED=$(tput setaf 1)
WHITE=$(tput setaf 7)
GREEN=$(tput setaf 2)
YELLOW=$(tput setaf 3)
CYAN=$(tput setaf 4)
LIGHT_CYAN=$(tput setaf 6)
STOP=$(tput sgr0)

for int in eth{0..2} wlan0 ppp{0..2}; do
    IP=$(/sbin/ifconfig 2>/dev/null $int | grep -oP 'inet\s+\K\d+\.\d+\.\d+\.\d+') && break
done


PROMPT_COMMAND=$(

»   cat<<-'EOF'

»   _temp_var=$val_ret _pipe_status="${PIPESTATUS[@]}"

»   if((val_ret==0)); then
»   »   _temp_var=$(( $(tr -s " " "+" <<< "$_pipe_status") ))
»   else
»   »   _temp_var=$val_ret
»   fi

»   if((_temp_var!=0)); then
»   »   if((EUID==0)); then
»   »   »   PS1="\[$RED\]\u\[$YELLOW\]@\[$WHITE\]\h\[$CYAN\]:\[$GREEN\]\w\[$WHITE\]\[$GREEN\]|\[$RED\]ERROR:$_temp_var\[$GREEN\]|\[$WHITE\] # \[$STOP\]"
»   »   else
»   »   »   PS1="\[$PURPLE\]\u\[$WHITE\]@\[$GREEN\]\h\[$GREEN\][\[$STOP\]${IP:-<UNDEF>}\[$GREEN\]]\[$WHITE\]:\[$GREEN\]\w|\[$RED\]ERROR:$_temp_var\[$GREEN\]|\[$WHITE\]$ $ \[$STOP\]"
»   »   fi

»   else
»   »   if((EUID==0)); then
»   »   »   PS1="\[$RED\]\u\[$YELLOW\]@\[$WHITE\]\h\[$CYAN\]:\[$GREEN\]\w\[$WHITE\] # \[$STOP\]"
»   »   else
»   »   »   PS1="\[$PURPLE\]\u\[$WHITE\]@\[$GREEN\]\h\[$WHITE\]:\[$GREEN\]\w\[$WHITE\] $ \[$STOP\]"
»   »   fi
»   fi

»   EOF

Try adding after that block the following:

PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND; }'printf "\033]0;host: %s\007" "${HOSTNAME%%.*}"'
