Direwolf Raspberry Pi RasPi startup with Screen rtl sdr #BASH #Linux #pi

Direwold_ScreenStartup

#In the dw-start.sh script, change the DWCMD definition to read:
#
#DWCMD="screen -dm -S direwolf bash -c 'rtl_fm -f 144.39M - | direwolf -c sdr.conf -r 24000 -D 1 -'"

#
#
#   And then, as that command is ran via cron, you can access that screen via:
#
#    screen -r direwolf
#
#   If you ctl-c out of the process on the console, you break the process as you are taking over 
#   its std-in, std-out.  Screen just provides the application switching, ctl-c kills the original
#   process, screen just helped you bring it to its demise. I hope you are happy
#
#    TL;DR: 
#      screen -dm -S myHandleName ls -lsa AndTheRestOfMyScript
#   
#    will let you run a command in the background, and to pull it  into the foreground:
#     screen -r myHandleName
