Doesn't inotifywait (from inotify-tools) do +> this exact same thing? + +When I first started wendy, I was not aware of inotifywait. It was just a good +programming exercise. + +With the time, I found wendy more and more useful, and added a few options to +make it faster and more 'generic' (It was first created to watch my mail +directory, to alert me of new mails). + +Today, I know that inotifywait can be used for everything wendy does Anyway, I +still prefer using wendy because of this: + + * inotifywait exits upon event reception  + * inotifywait does not allow to launch a command on event reception  + * inotifywait with multiple events can end in an infinite line  + * inotifywait only handle the file modification event (eg, wendy can use + the IN_ONLYDIR mask). + * inotifywait exits right when an event occur, wendy can treat all queued + events at a specific period + * inotify-tools : 164kb against 12kb for wendy (ok, not that relevant) + * I like the name 'wendy' better + + I'm aware of the '--monitor' flag, but the only way to exec a command with +this is a pain that implies read, a while loop and so on. + + In fact, you can, by doing "inotifywait -e <event> && command", and +wrapping it in a while loop. Well, don't forget to add a test to see if your +file still exists, to avoid infinite buggy loops. You'll end up with something +like: + + while test -e ~/path/to/my/file; do + inotifywait -e <event> ~/path/to/my/file && command + done + +Good luck with this, I prefer "wendy -m <mask> -e command" + + one flag per event. events written in words: + + inotifywait -e access -e create -e delete -e modify -e attrib /path/to/file + +I prefer + + wendy -m 774 ~/path/to/my/file + +--- + +> Would you prefer to fight one horse sized duck, or 10 duck sized horses ? + +Regarding size and number, I'd rather fight horses. Ducks are silly creatures.
