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 com- mands, since they will be taken to be part of the command. Similarly, comments are not allowed on the same line as environment variable set- tings. 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 subse- quent 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 filewatcherd(8) daemon. LOGNAME and USER are set to the command user, HOME is set to the home directory of the command user, unless explic- itly overriden. TRIGGER is set to the path that has triggered the com- mand 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 trig- ger 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 com- mand. 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. SEE ALSO kqueue(2), crontab(5), filewatcherd(8) FreeBSD Ports 14.quarterly October 20, 2015 WATCHTAB(5)
