NAME

       shatagd - Automatically maintain hash tags for files in a given directory

SYNOPSIS

       shatagd [-druv] [PATH]...

DESCRIPTION

       shatagd Is a daemon companion to shatag(1) that will monitor filesystem paths using inotify(7) and automatically recompute a tag whenever a
       file is written to.

OPTIONS

       -d, --daemon
	      Daemonize. You must use absolute file paths when using this option.

       -r, --recursive
	      Recursively watch sub-directories, as well as newly created directories.

       -u, --update
	      Only update already tagged files. See the shatag(1) manpage for pitfalls.

       -v, --verbose
	      Write to stdout the paths of files which have their tags recomputed.

BUGS

       Recursive mode is subject to an unavoidable race condition, due to a limitation of inotify.

       Relative paths do not work when daemonized, only use absolute paths.

REPORTING BUGS

       Report shatag bugs to the bugtracker at http://bitbucket.org/maugier/shatag,
