How to launch a KDE konsole with multiple tabs running various progs?

问题

I know how to start a Konsole with one executable running in it, and leave the Konsole open after the program ends. I can do this using a .desktop file and change some options in it.

But I would like one step further, to launch a KDE konsole with multiple tabs open, each running a particular program, and that when the program finishes it stays open and give you a prompt.

There's no man page for Konsole so I don't even know what options it can take. Or some d-bus calls? Thanks

Who ever sees beauty in the accepted solution is hopefully not in software development : ) This must be a one liner or a bug report must be submitted. Every other common terminal has this option. I did some research and the "almost one liner solution" is this:

Create a file configuring your tabulators like so and name it let's say "tabs":

title: %n;; command: /usr/bin/htop

title: %n;; command: /usr/bin/ncmpcpp

(Here's the full documentation: https://docs.kde.org/stable5/en/applications/konsole/command-line-options.html The called command binaries are examples. The "%n" will name the tab exactly like the command)

Execute it like so:

konsole --tabs-from-file path_to_tabs_file/tabs

Result: A new konsole window with 3 tabs, running defined binaries and one empty prompt. I couldn't get a bash script to run. But I did just a few minutes of testing.

This is a solution using qdbus, see D-Bus documentation. The Konsole docs doesn't say much about the interfaces used, so some experimenting is necessary. I've left comments in the code about the things I attempted but that didn't work.

This works in KDE 5.

#! /bin/bash
# Multi command start in various konsole tabs

# List of commands to run, with parameters, in quotes, space-separated; do not use quotes inside (see bash arrays)
COMMANDS=("/my/prog1 param" "/my/prog2 param2" "/my/prog3 param1 param2 param3")

# KDS=$KONSOLE_DBUS_SERVICE # This is a ref to current Konsole and only works in Konsole
# KDS=$(org.kde.konsole)    # This is found in some examples but is incomplete

qdbus >/tmp/q0              # Get the current list of konsoles
/usr/bin/konsole            # Launch a new konsole
# PID=$!                    # And get its PID - But for some reason this is off by a few
sleep 1
qdbus >/tmp/q1              # Get the new list of konsoles
# KDS=org.kde.konsole-$PID      
# KDS=org.kde.konsole       # Sometimes
KDS=$(diff /tmp/q{0,1} | grep konsole)  # Let's hope there's only one
#echo $KDS
KDS=${KDS:3}
echo $KDS

echo $KDS >/tmp/KDS
echo >>/tmp/KDS

qdbus $KDS >>/tmp/KDS || exit
echo >>/tmp/KDS

# See note https://docs.kde.org/trunk5/en/applications/konsole/scripting.html about using /Konsole
qdbus $KDS /Konsole >>/tmp/KDS
echo >>/tmp/KDS

FirstTime=1

for i in "${COMMANDS[@]}"
do 
    echo "Starting: $i"
    echo >>/tmp/KDS
    if [ $FirstTime -eq 1 ]
    then
        session=$(qdbus $KDS /Konsole currentSession)
        FirstTime=0
    else
        session=$(qdbus $KDS /Konsole newSession)
    fi
    echo $session >>/tmp/KDS

    # Test: Display possible actions
    qdbus $KDS /Sessions/${session} >>/tmp/KDS

    # Doesn't work well, maybe use setTabTitleFormat 0/1 instead
    # Title "0" appears to be the initial title, title "1" is the title used after commands are executed. 
    #qdbus $KDS /Sessions/${session} setTitle 0 $i
    #qdbus $KDS /Sessions/${session} setTitle 1 $i

    # The line break is necessary to commit the command. \n doesn't work
    qdbus $KDS /Sessions/${session} sendText "${i}
"

    # Optional: will ping when there's no more output in the window
    qdbus $KDS /Sessions/${session} setMonitorSilence true
done

Update 2016: the structure of qdbus has changed again. Here's an update of the above script (I left out the original since depending on your KDE version you may need one or the other):

#! /bin/bash
# Multi command start in various konsole tabs

# List of commands to run, with parameters, in quotes, space-separated; do not use quotes inside (see bash arrays)
COMMANDS=("echo 1" "echo 2" "echo 3")

# KDS=$KONSOLE_DBUS_SERVICE # This is the ref of the current konsole and only works in a konsole
# KDS=$(org.kde.konsole)    # This is found in some examples but is incomplete

qdbus >/tmp/q0              # Get the current list of konsoles
/usr/bin/konsole            # Launch a new konsole
sleep 1
qdbus >/tmp/q1              # Get the new list of konsoles
KDS=$(diff /tmp/q{0,1} | grep konsole)  # Let's hope there's only one
KDS=${KDS:3}
echo $KDS

echo $KDS >/tmp/KDS
echo >>/tmp/KDS

qdbus $KDS >>/tmp/KDS || exit
echo >>/tmp/KDS

# See note https://docs.kde.org/trunk5/en/applications/konsole/scripting.html about using /Konsole
qdbus $KDS /konsole >>/tmp/KDS
echo >>/tmp/KDS

FirstTime=1

for i in "${COMMANDS[@]}"
do 
    echo "Starting: $i"
    echo >>/tmp/KDS
    if [ $FirstTime -eq 1 ]
    then
        session=$(qdbus $KDS /Windows/1 currentSession)
        FirstTime=0
    else
        session=$(qdbus $KDS /Windows/1 newSession)
    fi
    echo $session >>/tmp/KDS

    # Test: Display possible actions
    qdbus $KDS /Sessions/${session} >>/tmp/KDS

    # The line break is necessary to commit the command. \n doesn't work
    qdbus $KDS /Sessions/${session} sendText "${i}
"

    # Optional: will ping when there's no more output in the window
    qdbus $KDS /Sessions/${session} setMonitorSilence true
done

I did some more digging and found and even more "subjectively" beautiful answer. Goal: start empty shell, music player and screen session running irssi in 3 different tabs in konsole:

Create a simple, executable script file with:

#!/bin/bash konsole --hold --new-tab & konsole --hold --new-tab -e $SHELL -c "/usr/bin/screen -DRS irssi-in-screen irssi" & konsole --hold --new-tab -e $SHELL -c "/usr/bin/ncmpcpp" &

The clue is not to execute the the command directly but to call a shell, that can take in all arguments passed. $SHELL is set to /bin/bash. This "issue" is documented here:

https://docs.kde.org/stable5/en/applications/konsole/commonissues.html

Quote: " Konsole treats arguments after the -e option as one command and runs it directly, instead of parsing it and possibly dividing it into sub-commands for execution. This is different from xterm.
konsole -e "command1 ; command2" does not work

konsole -e $SHELL -c "command1 ; command2" works
