# run-mozbot-from-crontab: Script for restarting mozbot from crontab
# Originally written by Joel Thornton <joelpt@eml.cc>
#
# This is good to use in your crontab for rebooting the bot
# automagically upon its untimely demise. Use a line such as this in
# your crontab:
#
# 0,5,10,15,20,25,30,35,40,45,50,55 * * * * $HOME/mozbot/run-mozbot-from-crontab
#
# Change the paths to your mozbot accordingly above and in the next
# line.

cd $HOME/mozbot

# Create an empty .pid file first if it doesn't exist.
touch ./mozbot.pid

ps -C mozbot.pl -o pid= | grep "`cat ./mozbot.pid`" ||
( ( ./mozbot.pl >& /dev/null & ) ;
