Startup Script

Sipador · Post by **Sipador** » Mon Oct 31, 2016 1:37 am

Hi Everyone,

I have an mplayer script I want to run once the desktop environment (and any other relent programs) starts up.

Tried to add:
@reboot /root/mplayer_script.sh

At the bottom of /etc/crontab
Sorry still learning my way around bash, loving dietpi btw

.

Thanks for any help!

Try this using a SystemD service to launch after graphical.target (copy and paste all into terminal):

Code: Select all

cat << _EOF_ > /etc/systemd/system/myscript.service
[Unit]
Description=myscript
After=graphical.target

[Service]
Type=oneshot
RemainAfterExit=yes

ExecStart=/bin/bash -c '/root/mplayer_script.sh'

[Install]
WantedBy=default.target
_EOF_
systemctl enable myscript.service
systemctl daemon-reload

reboot, then check the status with:

Code: Select all

systemctl status mplayer_script.sh -l

Hey, Fourdee thanks for the assistance! I followed it but ended up with:

Code: Select all

root@DietPi:~# systemctl status mplayer_script.sh -l
● mplayer_script.sh.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

Which is strange because if I just copy and paste

Code: Select all

root@DietPi:~#/root/mplayer_script.sh

it'll start playing the video. Could it be root privileges?

Thanks again for your help

My bad lol

Correct command is:

Code: Select all

systemctl status myscript.service -l

Ah yes that makes sense, interesting results:

So it does run the script, but when its run it can't see root directory or any contents. Is it because myscript.service is being run outside of root access?

Can you paste the contents of your script? I'll take a look.

Try defining the absolute filepath to big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4. eg:

Code: Select all

/root/mystuff/big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

Hey Fourdee,

Sorry for the late reply, went through exams and my image was corrupted so I went back and remade it.

Some of the names have changed but much the same as before.
On the plus side when I rebooted the audio was playing but the video didn't show, so that's positive step forward

.

This is the output from the script.

Thanks again!

Mplayer should work on fbdev, so not sure why there is no video. Does the video work when you run from the cmdline? Might also be SystemD, try adding StandardOutput=tty under the [Service] section of the service.

Failing that, lets try X11, change your script so that xinit is called, before mplayer, eg:

Code: Select all

xinit mplayer -fs -autosyn......................

Also, make sure you have X11 installed:

Code: Select all

dietpi-software install 6
