    inotifywatch

    
    
    
    

    SYNOPSIS

           inotifywatch  [-hvzrqf] [-e <event> ] [-t <seconds> ] [-a <event> ] [-d
           <event> ] <file> [ ... ]
    
    
    

    DESCRIPTION

           inotifywatch listens for filesystem  events  using  Linux's  inotify(7)
           interface,  then outputs a summary count of the events received on each
           file or directory.
    
    
    

    OUTPUT

           inotifywatch will output a table on standard out with  one  column  for
           each type of event and one row for each watched file or directory.  The
           table will show the amount  of  times  each  event  occurred  for  each
           watched  file or directory.  Output can be sorted by a particular event
           using the -a or -d options.
    
           Some diagnostic information will be output on standard error.
    
    
    

    OPTIONS

           -h, --help
                  Output some helpful usage information.
    
           -v, --verbose
                  Output some extra information on standard  error  during  execu-
                  tion.
    
           @<file>
                  When  watching  a directory tree recursively, exclude the speci-
                  fied file from being watched.  The file must be specified with a
                  relative  or  absolute  path  according to whether a relative or
                  absolute path is given for watched directories.  If  a  specific
                  path is explicitly both included and excluded, it will always be
                  watched.
    
                  Note: If you need to watch a directory or file whose name starts
                  with @, give the absolute path.
    
           --fromfile <file>
                  Read filenames to watch or exclude from a file, one filename per
                  line.  If filenames begin with @ they are excluded as  described
                  above.   If  <file>  is  '-',  filenames  are read from standard
                  input.  Use this option if you need to watch too many  files  to
                  pass in as command line arguments.
    
           -z, --zero
                  Output table rows and columns even if all elements are zero.  By
                  default, rows and columns are only output if they  contain  non-
    
           -r, --recursive
                  Watch all subdirectories of any directories passed as arguments.
                  Watches  will be set up recursively to an unlimited depth.  Sym-
                  bolic links are not traversed.  If new directories  are  created
                  within watched directories they will automatically be watched.
    
                  Warning:  If  you use this option while watching the root direc-
                  tory of a large tree, it may take quite a while until  all  ino-
                  tify watches are established, and events will not be received in
                  this time.  Also, since one inotify watch  will  be  established
                  per subdirectory, it is possible that the maximum amount of ino-
                  tify watches per user will be reached.  The default  maximum  is
                  8192;  it  can  be  increased  by  writing  to /proc/sys/fs/ino-
                  tify/max_user_watches.
    
           -t <seconds>, --timeout <seconds>
                  Listen only for the specified amount of seconds.  If not  speci-
                  fied,  inotifywatch  will  gather  statistics until receiving an
                  interrupt signal by (for example) pressing CONTROL-C at the con-
                  sole.
    
           -e <event>, --event <event>
                  Listen for specific event(s) only.  The events which can be lis-
                  tened for are listed in the EVENTS section.  This option can  be
                  specified  more  than once.  If omitted, all events are listened
                  for.
    
           -a <event>, --ascending <event>
                  Sort output ascending by event counts for the  specified  event.
                  Sortable events include 'total' and all the events listed in the
                  EVENTS  section  except  'move'  and  'close'  (you   must   use
                  'moved_to',   'moved_from',   'close_write'  or  'close_nowrite'
                  instead).  The default is to sort descending by 'total'.
    
           -d <event>, --descending <event>
                  Sort output descending by event counts for the specified  event.
                  Sortable events include 'total' and all the events listed in the
                  EVENTS  section  except  'move'  and  'close'  (you   must   use
                  'moved_to',   'moved_from',   'close_write'  or  'close_nowrite'
                  instead).  The default is to sort descending by 'total'.
    
    
    

    EXIT STATUS

           0      The program executed successfully.
    
           1      An error occurred in execution of the program.
    
                  extended attributes etc.
    
           close_write
                  A watched file or a file within a watched directory was  closed,
                  after being opened in writeable mode.  This does not necessarily
                  imply the file was written to.
    
           close_nowrite
                  A watched file or a file within a watched directory was  closed,
                  after being opened in read-only mode.
    
           close  A  watched file or a file within a watched directory was closed,
                  regardless of how it was opened.  Note  that  this  is  actually
                  implemented   simply  by  listening  for  both  close_write  and
                  close_nowrite, hence all close events received will be output as
                  one of these, not CLOSE.
    
           open   A  watched file or a file within a watched directory was opened.
    
           moved_to
                  A file or directory was moved into a  watched  directory.   This
                  event  occurs  even  if the file is simply moved from and to the
                  same directory.
    
           moved_from
                  A file or directory was moved from a  watched  directory.   This
                  event  occurs  even  if the file is simply moved from and to the
                  same directory.
    
           move   A file or directory was moved from or to  a  watched  directory.
                  Note  that  this is actually implemented simply by listening for
                  both moved_to and moved_from, hence all  close  events  received
                  will be output as one or both of these, not MOVE.
    
           move_self
                  A  watched  file  or  directory was moved. After this event, the
                  file or directory is no longer being watched.
    
           create A file or directory was created within a watched directory.
    
           delete A file or directory within a watched directory was deleted.
    
    
    
    

    EXAMPLE

           Watching the '~/.beagle' directory for 60 seconds:
    
           % inotifywatch -v -e access -e modify -t 60 -r ~/.beagle
           Establishing watches...
           Setting up watch(es) on /home/rohan/.beagle
           OK, /home/rohan/.beagle is now being watched.
           Total of 302 watches.
           Finished establishing watches, now collecting statistics.
           Will listen for events for 60 seconds.

    BUGS

           There are race conditions in  the  recursive  directory  watching  code
           which  can cause events to be missed if they occur in a directory imme-
           diately after that directory is created.  This is probably not fixable.
    
           It is assumed the inotify event queue will never overflow.
