fswatch is a utility to guard changes in a file system. fswatch is
composed of three programs: fswbuild, fswcmp, fswshow. fswbuild builds
file system information database. fswcmp compairs two database files
and returns what changes a in file system have been introduced. fswshow
shows contents of database file.
fswatch can collect the following information about files: inode,
links, uid, gid, mode, size, flags, ctime, checksum (sha1) ; and can
show which files were added, deleted or changed.
fswatch is one of many similar utilities. the main difference is the
configuration. you can define different settings for every directory
in a directory tree.
