This one is for coders:
I found out a way to capture the output from screen in real time. See the lines:
This run screen for 20 seconds (timeout command) and saves output to file ~/kk003_telegram_data/files/output_miner_from_screen (script command). -dr forces to attach miner (so if user have screen open in a terminal will close it and the script will do its job). After 20 seconds miner is detached without need to send CTRL+d.
This works better if ran from a non interactive terminal, ejem: from nvoc system
.
This means it is possible to capture the output of any miner even if all of it shows only on terminal (no log file, web server, argument -L on screen, etc).
I hope it will be useful for you too.
PD: if you use "tail -f file" to watch the output in real time don't trust what you see. The real output is in the file (do a cat file or whatever). Keep in main, if you log the output of your script probably you'll get those 20 seconds from screen in the log file too.
Code:
function genoil_statics ()
{
#### Arrange the output for Genoil statics
if [[ "$ETHMINER_or_GENOIL_or_CLAYMORE" == "GENOIL" ]]; then
# Check if Genoil is running. Note that I have to search the full path as there is a few miners with the same exec's name
ps aux | grep -v grep | grep miner | grep -q "$KEY_GENOIL"
if [[ $? -eq 0 ]]; then
GENOIL_IS_RUNNING="YES"
TIMEOUT_FOR_TIMEOUT_IN_SECONDS=20 # The timeout for the command timeout to wait
GENOIL_NUMBER_OF_HASHRATES_TO_SHOW=3 # Default 3, and I want to keep this value independent for each miner
echo
echo "It seems that GENOIL is running!!"
