You'll lose cgminer's interactive ui that way.
Practice a little bit of screen manipulation first, then revisit the script.

open two bash terminals

first terminal

Code:

screen -dmS miner1

second terminal

Code:

screen -x miner1

first terminal

Code:

screen -S miner1 -X stuff "/home/pi/git/vthoang/cgminer/cgminer --gekko-2pac-freq 180 -o stratum+tcp://bch.viabtc.com:3333 -u usaminer.2 -p 1 --suggest-diff 64 ^M"

first terminal

Code:

pkill cgminer

first terminal

Code:

screen -S mine -X stuff "/home/pi/git/vthoang/cgminer/cgminer --gekko-2pac-freq 180 -o stratum+tcp://bch.viabtc.com:3333 -u usaminer.2 -p 1 --suggest-diff 64 ^M"

Very cool, i see it working when i manually input the commands (it seems i had to install screen into raspbian stretch first). Now i will have to make it into a script. Thanks vh!

One question, what does the ^M do at the end of the cgminer configs command? I dont see that in the list of configs for cgminer.

One question, what does the ^M do at the end of the cgminer configs command? I dont see that in the list of configs for cgminer.

The ^M is an artifact from Windows, not to be worried about. Windows uses Carrage-Return+Linefeed as the end of line codes in its text files. *NIX systems only use Carrage-Return. The artifact doesn't affect running the script.

[vh]

Yes, ^M is interpreted by screen to send a (Cr) into the terminal.

The remaining piece:

forever run cgminer with a restart every 4 hours.

second terminal

Code:

while [ true ]; do
    timeout 4h /home/pi/git/vthoang/cgminer/cgminer --gekko-2pac-freq 180 -o stratum+tcp://bch.viabtc.com:3333 -u usaminer.2 -p 1 --suggest-diff 64
    sleep 5
done

finishing it up:

runtask.sh

Code:

#!/bin/bash
screen_name=miner1

if [[ `screen -ls | grep $screen_name | wc -l` -eq 0 ]]; then 
    screen -dmS $screen_name
fi

screen -S $screen_name -X stuff ^C^C^C

screen -S $screen_name -X stuff "
while [ true ]; do

So my script writing abilities arent that good, but im just trying to make a simple script (i mean ELI5 simple) and here is what i got so far.

Code:

#!/bin/bash
screen -dmS miner1
screen -S miner1 -X stuff "timeout 10s /home/pi/git/vthoang/cgminer/cgminer --gekko-2pac-freq 180 -o stratum+tcp://bch.viabtc.com:3333 -u usaminer.2 -p 1 --suggest-diff 64 ^M
done"
screen -S miner1 -r

Now here is where i am stuck. (i know i have this timeout at 10s) but once the timeout is done the screen goes back to command line and the rest of my script doesnt run. Now when i type in exit on the command line then the next part of my script starts up (which is a replica of the above script). I have tried everything to get the exit command to go into the command line after the first part of the script runs, but nothing happens.

What can i do to get my screen to exit so the rest of my script can run?

Thanks and sorry for the elementary abilities. I am having fun learning on the way, it has taken me 5 days to get where i am now!

Here is where i am stuck

Code:

#!/bin/bash
{
#
#first instance
#
screen -dmS miner1
screen -S miner1 -X stuff "timeout 10s /home/pi/git/vthoang/cgminer/cgminer --gekko-2pac-freq 180 -o stratum+tcp://bch.viabtc.com:3333 -u usaminer.2 -p 1 --suggest-diff 64 ^M
done"
screen -S miner1 -r

i need this to insert exit into the command line and go

#
#second instance
#
screen -dmS miner1
screen -S miner1 -X stuff "timeout 30s /home/pi/git/vthoang/cgminer/cgminer --gekko-2pac-freq 180 -o stratum+tcp://bch.viabtc.com:3333 -u usaminer.2 -p 1 --suggest-diff 64 ^M
done"
screen -S miner1 -r

i need this to insert exit into the command line and go

#
#third instance
#
screen -dmS miner1
screen -S miner1 -X stuff "killall screen
exit"
screen -S miner1 -r

} 2>&1 | tee script-error.log

[vh]

Don’t attach to the screen.
Run your main script file inside it.

Thanks vh, i think i figured out a decent crontab with an added @reboot command. So every 4 hours i start by killall screens, rerun the miner script after 5 minutes and then reboot my machine at 1am and start everything up again. Testing it today seems to be working so far, will test it the rest of the week to see how successful my method is.

Thanks for the help!

This is probably old news, but the latest version of cgminer that I checked out from https://github.com/vthoang/cgminer.git is a lot newer than what I checked out just a few months ago.  In particular, cgminer always starts at 100mhz then incrementally increases the clockrate to what was set on the command line, so we can figure out the max clockrate more easily.  Pretty cool!  Happy 4-20!

hello again everybody,

i've now decided to move my stick onto a rasp pi.

ive setup a cron job so that whenever the pi is rebooted a script called runMiner.sh is run. in my runMiner.sh file i have this:

Code:

#!/bin/bash

sudo /home/pi/git/vthoang/cgminer/cgminer -o stratum+tcp://eu.stratum.slushpool.com:3333 -u zbw123.worker1 -p x --gekko-2pac-freq 200

 i have also done this so that the terminal starts when the pi reboots


nano ~/.config/lxsession/LXDE-pi/autostart

Added this line to the end of the file:

@lxterminal

ok so i'm sure you guys are falling off your seat with laughter but basically all that happens is the terminal opens up but the miner doesnt start.

somehow i need to get the command into the terminal.

thanks for any help
zac

Not sure if it's exactly what you're looking for, but if you scroll up the page just a bit there's quite a bit of discussion on cron jobs and startup scripts.

Yeah thanks I tried to follow that exactly and got myself in a bit of mess and couldn't get it to work.

Hello zac123, I think you are pretty close. You need to specify the path to the runMiner.sh after the @lxterminal command; on the same line.

hey MG thanks for the reply. was just about to type out my progress so far an then you posted this message.

i have just got it to work by doing the following:

show hidden files
open .bashrc
locate the very bottom and paste:

~/git/vthoang/cgminer/runMiner.sh

right click on runMiner.sh and allow anybody to run the file under permissions.

and hey presto it works.

ref: http://blog.startingelectronics.com/auto-start-a-desktop-application-on-the-rapberry-pi/

I will also try pasting the cmd after @lxterminal to confirm that as well.

now all i need to do is to have the rasp pi automatically reboot every so often and we're away!

slight problem with the above. it means i can open a separate terminal to do anything else. when i click to open another terminal window its runs the same script again and tries to start the miner. hmm

your way is better

@lxterminal -e /path/to/script.sh

[zac123]

ok, calling any raspberry pi users!

i have the pi running cgminer, my sticks are at 200freq with no HW errors.

i found out very quickly that the pi crashes after not very long mining so i worked out a way (as above) to restart the miner to try and keep it fresh. like so:

so on the crontab i have:

Code:

pi@raspberrypi:~ $ crontab -l
*/59 * * * * sudo reboot

on the reboot i have in the autostart file:

Code:

@lxterminal -e /home/pi/git/vthoang/cgminer/runMiner.sh

and the script that is called looks like this:

Code:

#!/bin/bash

sudo /home/pi/git/vthoang/cgminer/cgminer -o stratum+tcp://eu.stratum.slushpool.com:3333 -u zbw123.worker1 -p x --gekko-2pac-freq 200

this all works bloomin lovely, i can sit and watch it reboot and the sticks start mining just as they should, excellent.

however, as soon as i turn my back.... like when i go to bed for example the pi crashes and cannot be accessed at all. the sticks are no longer flashing and there is only one option and that is to do a hard reset.

it doesn't make any difference if i reboot every few hours or every few minutes or if i mine with one stick or seven.

the sticks sit in a powered usb which can supply up to 2.1amp per port.

other people are doing what i'm doing successfully so it must be possible. i just need to get it setup right.

as always any help muchly appreciated.
zac

Did you do the slub thing?

Try to add slub_debug=FP to /boot/cmdline.txt and reboot

That fixed some serious lockup issues I was having with the Pis on the Terminus testing table.

ahh ok, no i havent tried this. having troubling editing that file and the permissions wont let me change them. one sec


did it via terminal. rebooting now...

[zac123]

ok, some good news, some not.....

when i woke up this morning the pi had not crashed. so adding slub_debug=FP has definitely improved things. but.... out of the three sticks i left in last night one of them was reporting OFF when i woke up.

as yet i can seem to get it restarted. ive tried using the miner options like, E enable, R reset etc etc

there are no HW errors at all.

anyone else had this?

edit.... i should add i'm keeping them very cool with fans pointing directly on them.
