Examples of using the gearman tool to create boilerplate clients and workers

client.sh

# gearman client that sends no data to the "ping" function
gearman -f ping -s

# gearman client that sends the string "pong" to the "ping" function
echo "pong" | gearman -f ping

# gearman client that sends a json string to the "process" function
echo '{"order":4985343}' | gearman -f process

# gearman client that reads data from a order.json file 
# and sends to the "process" function
gearman -f ping < order.json

worker.sh

# gearman worker listening for "resize" function
gearman -w -f "resize"

# gearman worker listening for "generate_po" function and exiting after 5 jobs
gearman -w -f generate_po -c 5
