Change konsole tab title from command line and make it persistent?

Question

How can I change the konsole tab title? By default, it\'s set to %u : %n, so it always changes automatically.

I can set it with:

qdbus org.

Posting my own solution to this old question, because

• OP solution does not work on newer(?) KDE systems due to the hard-coding of the service name to org.kde.konsole
• the answers based on echo require a permanent change to konsole settings

After reading the Scripting Konsole chapter in the konsole documentation I wrote these bash functions which can be added to $HOME/.bashrc:

set-konsole-tab-title-type ()
{
    local _title=$1
    local _type=${2:-0}
    [[ -z "${_title}" ]]               && return 1
    [[ -z "${KONSOLE_DBUS_SERVICE}" ]] && return 1
    [[ -z "${KONSOLE_DBUS_SESSION}" ]] && return 1
    qdbus >/dev/null "${KONSOLE_DBUS_SERVICE}" "${KONSOLE_DBUS_SESSION}" setTabTitleFormat "${_type}" "${_title}"
}
set-konsole-tab-title ()
{
    set-konsole-tab-title-type $1 && set-konsole-tab-title-type $1 1
}

Example 1: set both local & remote tab formats

$ set-konsole-tab-title test

Example 2: leave remote tab format unchanged

$ set-konsole-tab-title-type test

Example 3: leave local tab format unchanged

$ set-konsole-tab-title-type test 1

You can also use this function to set the tab title dynamically to %w for the echo solutions.
