There is nothing special in gulp to limit running multiple processes or alert you to an already running gulp process.

Use regular Unix techniques to check if a process is running. Use a supervisor like supervisord or runit to automatically restart processes.

#the program pidof will set the variable $? to either
#1 or 0 in bash depending on if it finds a process
#with that name.  It will also print out all the matching
#process IDs to the command line
pidof gulp
echo $?  #1 if there is no process called gulp
         #0 if there is a process called gulp
if pidof gulp; then 
   echo 'gulp is alive';
else
   echo 'we need some support over here!'
   ./node_modules/.bin/gulp watch &
   sleep 3
fi
