### Usage
###
usage() {
echo "Usage: `basename $0` <-r|-s> <get|delete> <resource-name>"
echo "Options:"
echo " -r ... resources you are a receiver (valid for resource lists and deletions, default)"
echo " -s ... resources you are the sender (valid for resource lists and deletions)"
echo " -a ... all resources (valid for resource lists and deletions)"
echo " -v ... verbose output"
echo " -h|? ... usage"
echo ""
cat - <<'EOF'
Examples:
List all courselinks where I'm a receiver of:
participant.sh get /campusconnect/courselinks
or
participant.sh -r get /campusconnect/courselinks
List all courselinks where I'm the sender of:
participant.sh -s get /campusconnect/courselinks
Show the courselink representation with id 2257:
participant.sh get /campusconnect/courselinks/2257
Delete the courselink representation with id 2257:
participant.sh delete /campusconnect/courselinks/2257
Delete courselinks where I'm a receiver of:
participant.sh -r delete /campusconnect/courselinks
Delete courselinks where I'm the senedr of:
participant.sh -s delete /campusconnect/courselinks
Delete courselinks where I'm a receiver or sender of:
participant.sh -a delete /campusconnect/courselinks
List all events:
participant.sh get /sys/events
Get oldest event (fifo):
participant.sh get /sys/events/fifo
Get and delete oldest event (fifo):
participant.sh delete /sys/events/fifo
FAQ:
Q: You want to delete all events.
A: Just call "participant.sh delete /sys/events/fifo" in a loop:
for i in `seq 10`; do ./participant.sh delete '/sys/events/fifo' ; done
This will get and delete always the oldest event. If there no more events
you will get back nothing. Just repeat the loop until you don't get anything
back.
