Why does inotitywait with "echo '---' >> file" only emit an "OPEN" event?

Question

Why does echo "---" >> file only generate a ./ OPEN file event? Shouldn't it generate other events too?

For example:

# In a script:
while true; do
  change=$(inotifywait -q -r . )
  echo $change
done

# Somewhere else:
echo "--" >> file
echo "--" >> file
echo "--" >> file

Answer 1

it is exiting after the first event and starting the loop over, by the time the first watch is removed and the second added, the events have already transpired. You can try:

inotifywait -q -m -r . | while read CHANGE; do
    case "$CHANGE" in
        *)echo $CHANGE;;
    esac
done

the -m will continue monitoring after the first event
