I am trying to delete a created file with inotify but it doesn't work:
inotifywait -r --format '%w%f' -e create /test && rm $FILE
when i create a file in /test I get this:
/test/somefile.txt
rm: missing operand
Try `rm --help' for more information.
so it seems that the $FILE variable is not passed to the rm command... how can I do this correctly? Thanks.

How does Inotify Work? The Inotify develops a mechanism for monitoring file system events, which watches individual files & directories. While monitoring directory, it will return events for that directory as well as for files inside the directory.
inotify (inode notify) is a Linux kernel subsystem created by John McCutchan, which monitors changes to the filesystem, and reports those changes to applications. It can be used to automatically update directory views, reload configuration files, log changes, backup, synchronize, and upload.
Inotify Watch helps to keep track of the file changes under the directories on “watch” and report back to the application in a standard format using the API calls. We can monitor multiple file events under the watched directory using the API calls.
When launching your inotifywait once (without the -m flag), you can easily use xargs :
inotifywait -r --format '%w%f' -e create /test -q | xargs /bin/rm
that will wait for a file creation in /test, give the filename to xargs and give this arg to /bin/rm to delete the file, then it will exit.
If you need to continuously watch your directory (with the -m param of inotifywait), create a script file like this :
inotifywait -m -r --format '%w%f' -e create /test | while read FILE
do
/bin/rm $FILE
done
And then, every newly file created in you /test directory will be removed.
