How do I fire-and-forget restart the Plasma shell from a Bash script?

I have a script that patches a bunch of xml files with sed in "/usr/share/plasma/plasmoids". This part is OK.
The last 2 lines of the Bash script, restart the Plasma shell and exit the script :

kquitapp5 plasmashell && kstart plasmashell && kstart kwin --replace &
exit

The issues are :

1. that after running the script, I have to hit Ctrl+C to get back to the command prompt

2. messages keep on being logged to the terminal window where I ran the script

3. I get various error/warning message which worry me

In the script, I commented the line that restarts the Plasma Shell for now. I now run the script to patch the files and then execute the Plasma restart from Krunner. But I prefer to run the script and restart the shell in a fire-and-forget manner. Or possibly call Krunner from the script to restart the shell, but this doesn't seem possible.

Re: How do I fire-and-forget restart the Plasma shell from a Bash script?

1. I doubt you need to hit Ctrl-C, I suspect hitting Enter would work just as well - or you could even just type a command.  You are at a functional shell prompt, but excess information has simply been echoed to the screen which is just your second issue.

2. These messages are echoed to the screen as you haven't directed them anywhere else.  Do so by redirecting stdout and stderr.

3.  I'm not familiar with plasma, but these could all be normal warnings that you just wouldn't otherwise see because you don't normally launch plasma from an interactive shell.  Check your xorg logs or display manager logs, or wherever this output is normally sent to compare.

Re: How do I fire-and-forget restart the Plasma shell from a Bash script?

I have a script that patches a bunch of xml files with sed in "/usr/share/plasma/plasmoids". This part is OK.
The last 2 lines of the Bash script, restart the Plasma shell and exit the script :

kquitapp5 plasmashell && kstart plasmashell && kstart kwin --replace &
exit

Hi,

/usr/bin/ kstart5

instead of kstart which doesn't exist ?

1. Yes you are right. Looks like any key will do. Thanks!
2. Redirecting seems to work. For now the script now ends with the 4 lines below. Thanks!

kquitapp5 plasmashell > ~/kquitapp5_plasmashell.log 2>&1 &
kstart plasmashell > ~/kstart_plasmashell.log 2>&1 &
kstart kwin --replace > ~/kstart_kwin.log 2>&1 &
exit

3. I'll have to look into this. I'll pick a moment when I have some time to kill for that. Because I have no idea where that output would usually go. I meant the following messages, so it is easy to lookup I guess. Output is now saved in 3 log files, with the log file produced for kquitapp5 always being zero length. journalctl -xb --since="2019-04-04 11:28:00" only resulted in me recognising the sed commands (from the script) being executed as root. Possibly because of the redirection.
kstart(4776) main: Omitting both --window and --windowclass arguments is not recommended by the kstart plasmashell command, and kstart(4777) main: Omitting both --window and --windowclass arguments is not recommended by the kstart kwin command. And QObject::startTimer: Timers cannot be started from another thread which was displayed a few times long after the script had finished running (before the change).

I have a script that patches a bunch of xml files with sed in "/usr/share/plasma/plasmoids". This part is OK.
The last 2 lines of the Bash script, restart the Plasma shell and exit the script :

kquitapp5 plasmashell && kstart plasmashell && kstart kwin --replace &
exit

Hi,

/usr/bin/ kstart5

instead of kstart which doesn't exist ?

kstart does exist for me, on all of my boxes. See below what sort of output I get on my box.
This script was started a few years back, and I bumped into it yesterday while cleaning out a backup folder on an unused external drive. I don't know why both are/were installed, and maybe I should use kstart5 going forward. I'll read into it, because I don't know the differences, nor down and upsides between usage of the two (yet). Thanks for pointing this out though.

[bobbybabes@ladyluck 5.0.2 ~]# whereis kstart kstart5
kstart: /usr/bin/kstart
kstart5: /usr/bin/kstart5
[bobbybabes@ladyluck 5.0.2 ~]# ls -lah --time-style=full-iso /usr/bin/kstart /usr/bin/kstart5
-rwxr-xr-x 1 root root 42K 2018-09-07 20:17:41.000000000 +0200 /usr/bin/kstart

No, not installed from the AUR. I had already checked that before my previous post, that's why I wrote : "I don't know why both are/were installed, .....". Check the screenshot. Also, the kstart package from the AUR is at version 4.2 and was last updated 2017-10-26.
And obviously I can't display reverse dependencies with pacman -Sii kstart and pacman -Qii kstart (or kstart5) because kstart and kstart5 are not packages.

Correction, obviously you can:

pacman -Qqo /usr/bin/kstart* | pacman -Qi -

Re: How do I fire-and-forget restart the Plasma shell from a Bash script?

Why are you posting images of text? Please don't.

It proves that the output of the commands (so not code at all) is valid. With text I could have mocked up the output of the commands. But if SEO is more important, so be it. To avoid future issues, I will not post images in this forum anymore at all, of everything. It is what it is, that's the rules here. If this thread had not gone off-topic with "instead of kstart which doesn't exist ?", I wouldn't have been asked about posting images of code and having to justify the reason. But derailing a thread by going off-topic with an untruth is apparently OK, because it is not questioned. Remember, kstart does exist, and in the OP I even wrote that it is causing output to the terminal. Which I want to get rid of. Surely an error message would have been thrown had kstart not existed, or wasn't soft linked to kstart5.

And obviously I can't display reverse dependencies with pacman -Sii kstart and pacman -Qii kstart (or kstart5) because kstart and kstart5 are not packages.

Correction, obviously you can:

pacman -Qqo /usr/bin/kstart* | pacman -Qi -

@Trilby thanks for your last post. But I'm leaving this thread for what it is. It has been derailed already and I'm getting burned for posting images because of the derailment.

Rosetta lists just Display packages which require X to be installed, aka show reverse dependencies.    pacman -Sii and List all packages which are required for the given package, aka show dependencies.    pacman -[S|Q]i. I had to lookup -o, --owns <file>.

Output for your exact command :

Output for your command foir kstart only. It looks like it was installed by kdebase-runtime, which in turn was installed as a dependency of another package. : So in fact this whole kstart vs kstart5 that was brought into this thread is just noise. For trying to prove this, I get burned and have to explain myself.

Re: How do I fire-and-forget restart the Plasma shell from a Bash script?

Well it's an old kde4 package that was moved to AUR, if you have a known reason to need it you probably can keep it installed, otherwise you might want to remove it and in general use kstart5 so that you are using the updated version.

However to get this back on track, do you still have an issue with regards to your original question? If the original issue is solved, please mark your topic as such as such: https://wiki.archlinux.org/index.php/Co … ow_to_post
