Restart ES by commandline?

Dochartaigh

Like reboot the entire system? sudo reboot

Or JUST EmulationStation? (which I use "killall emulationstation" I believe). You can also properly quit EmulationStation to the command line by hitting Start > Quit > Quit EmulationStation (which should properly shut it down), then just type emulationstation in Terminal to restart it.

I just want to restart ES. I do not want to reboot neither I want to use the standard quit dialog from ES by using a controller :)
I am looking for a way to restart ES from another terminal session without interacting in any way with the TV / controller / ES.

Currently I am using killall emulationstation && emulationstation & to restart it.

@daeks just type exit or emulationstation

@daeks you could also check for process id by ps aux commend and then type kill command with the specific process id but I still think that your option is better.
You can always make new alias in .bashrc file to assign this long command to just one small word like eg. eskill.

Currently I am struggeling with:

export HOME=/home/pi
export TERM="linux"
emulationstation > /dev/tty1 2>&1 &

ES gets restarted but starting a game results in "Unable to open /dev/tty"

What I am missing here? :( @BuZz can you help?

Just trigger the ES launch script to restart it. Create /tmp/es-restart and send a SIGINT to es.

[edit] corrected filename.

@BuZz omg, it could be simple.... thank you very much!
My final solution was sudo openvt -c 1 -s -f emulationstation 2>&1 but your way is much more appreciated :)
I am doing now echo "" > /tmp/es-restart && killall emulationstation

BuZz

@daeks said in Restart ES by commandline?:

can just use touch - touch /tmp/es-restart

daeks

@BuZz thanks :) do you also know a quick way to close a running game? Restarting ES while a game is running looks not very good :/

BuZz

@daeks you can kill retroarch, but if it's something else that won't help.

Something like this might be better - get the child process of the runcommand process, and send a SIGINT to that.

kill $(pgrep -P $(pgrep -f "bash /opt/retropie/supplementary/runcommand/runcommand.sh"))

@BuZz I have tested it on some emulators. it looks like that it does not catch everything. As an example scummvm is still running although the runcommand.sh was killed.

@daeks I would try to kill the command present on 4th line of /dev/shm/runcommand.info.

BuZz

@daeks strange as it shouldn't kill runcommand but the child. You could try meleu's suggestion, or just don't allow restarting if a game is running.
