WATCHTAB(5)		       File Formats Manual		     WATCHTAB(5)

NAME
     watchtab -- tables for driving filewatcherd

DESCRIPTION
     A	watchtab file contains instructions to the filewatcherd(8) daemon of the
     general form: ``run this command when these events happen to  the	file  at
     this path''.

     Blank  lines  and	leading  spaces and tabs are ignored.  Lines whose first
     non-space character is a pound-sign (#) are comments, and are ignored. Note
     that comments are not allowed on the same line as watchtab commands,  since
     they  will be taken to be part of the command.  Similarly, comments are not
     allowed on the same line as environment variable settings.

     An active line of a watchtab will be either an  environment  setting  or  a
     command.  An environment setting is of the form

	 name = value

     where the spaces around the equal-sign (=) are optional, and any subsequent
     non-leading  spaces  in  value  will be part of the value assigned to name.
     Note that name cannot contain any blackslash or tabulation.

     Several environment  variables  are  set  up  automatically  by  the  file-
     watcherd(8)  daemon.  LOGNAME and USER are set to the command user, HOME is
     set to the home directory of the command user, unless explicitly overriden.
     TRIGGER is set to the path that has triggered the command execution.

     The format of a watchtab command  is  a  tabulation-separated  sequence  of
     fields, interpreted as follow:

     path     Path of the file to watch.

     events   Set of events which trigger the command. It can either be a single
	      star-sign  (*),  or  a  punctuation-separated list of names among:
	      DELETE, WRITE, EXTEND, ATTRIB,  LINK,  RENAME  and  REVOKE.  Their
	      meaning is defined in kqueue(2) for fflags for EVFILT_VNODE.

     delay    Number  of  seconds, allowing a decimal point, between the trigger
	      and when the command is actually run.

     user     User, and optionally group preceded by a colon sign (:), to change
	      to before running the command.

     chroot   Path of a directory in which to chroot before running the command.

     command  The command to run.

     When less than 6 fields are given in a command line, the  chroot  value  is
     considered  omitted, and chroot will be performed.  When less than 5 fields
     are given, the user value is considered omitted, and no  setuid  or  setgid
     will  be  performed.  When less than 4 fields are given, the delay value is
     considered as zero.  It is an error to provide less than 3 fields.
