Hi, @panwarharsh15 ! Here is an etcdctl watch command example:

./etcdctl watch foo -- sh -c "env | grep ETCD_WATCH_"

# PUT
# foo
# bar
# ETCD_WATCH_REVISION=11
# ETCD_WATCH_KEY="foo"
# ETCD_WATCH_EVENT_TYPE="PUT"
# ETCD_WATCH_VALUE="bar"

We can split this command ./etcdctl watch foo -- sh -c "env | grep ETCD_WATCH_" by -- into two parts: one is ./etcdctl watch foo, and the other part is a shell command: env | grep ETCD_WATCH_". It indicates that execute the watch command ./etcdctl watch foo and perform the shell command env | grep ETCD_WATCH_ when the watch command is triggered.

And currently, the watch sub-command in xlinectl doesn't support this way. We can only perform xlinectl watch foo without -- sh -c "env | grep ETCD_WATCH_".
