Different flags to use in incron (According to their website):

 
There are two sets of magic flags here - the first is the IN_CLOSE_WRITE, and the second is $@/$#. The second set of flags is simpler to explain as there are fewer of them:

 •$$ - a dollar sign

 •$@ - the watched filesystem path (ie. the path you're watching)

 •$# - the event-related file name

 •$% - the event flags (textually)

 •$& - the event flags (numerically)

The actual event flags include IN_CLOSE_WRITE, which means that a file was closed for writing. The full list of supported flags includes:

 •IN_ACCESS File was accessed (read)

 •IN_ATTRIB Metadata changed (permissions, timestamps, extended attributes, etc.)

 •IN_CLOSE_WRITE File opened for writing was closed

 •IN_CLOSE_NOWRITE File not opened for writing was closed

 •IN_CREATE File/directory created in watched directory

 •IN_DELETE File/directory deleted from watched directory

 •IN_DELETE_SELF Watched file/directory was itself deleted

 •IN_MODIFY File was modified

 •IN_MOVE_SELF Watched file/directory was itself moved

 •IN_MOVED_FROM File moved out of watched directory

 •IN_MOVED_TO File moved into watched directory

 •IN_OPEN File was opened

Multiple flags may be separated via commas.
