# Startup Script |
||||
# ==================================================================== |
||||
# I wrote this script with the intention of using it to start a |
||||
# cron-job -- when the Raspberry Pi is turned on. Before you set the |
||||
# cron-job up, you must make sure you have either ran the |
||||
# "make-log-files.sh" script or created the appropriate log file and |
||||
# folder at the location specified at "logFile" below. |
||||
# ==== |
||||
# Please note: This script calls another (Python) script at the end of |
||||
# it. The code in the Python script (relay.py) is an infinite-loop |
||||
# so you will need to kill it manually or turn-off the Raspberry Pi. |
||||
# ==== |
||||
# I put the "sleep 60" call at the start to reduce any errors |
||||
# occurring because a part of the system (I.E. curl) has not finished |
||||
# loading. 60 seconds is a little excessive but I wrote this script |
||||
# with the expectation of it running on an unmanned Raspberry Pi. So, |
||||
# reliable/consistent behaviour is my preference over "fast start-up |
||||
# times". |
