+.Nm +utility compares a file hierarchy against a specification, +creates a specification for a file hierarchy, or modifies +a specification. +.Pp +The default action, if not overridden by command line options, +is to compare the file hierarchy rooted in the current directory +against a specification read from the standard input. +Messages are written to the standard output for any files whose +characteristics do not match the specification, or which are +missing from either the file hierarchy or the specification. +.Pp +The options are as follows: +.Bl -tag -width Xxxexcludexfilexx +.It Fl b +Suppress blank lines before entering and after exiting directories. +.It Fl C +Convert a specification into +a format that's easier to parse with various tools. +The input specification is read from standard input or +from the file given by +.Fl f Ar spec . +In the output, each file or directory is represented using a single line +(which might be very long). +The full path name +(beginning with +.Dq \&./ ) +is always printed as the first field; +.Fl K , +.Fl k , +and +.Fl R +can be used to control which other keywords are printed; +.Fl E +and +.Fl I +can be used to control which files are printed; +and the +.Fl S +option can be used to sort the output. +.It Fl c +Print a specification for the file hierarchy originating at +the current working directory (or the directory provided by +.Fl p Ar path ) +to the standard output. +The output is in a style using relative path names. +.It Fl D +As per +.Fl C , +except that the path name is always printed as the last field instead of +the first. +.It Fl d +Ignore everything except directory type files. +.It Fl E Ar tags +Add the comma separated tags to the +.Dq exclusion +list. +Non-directories with tags which are in the exclusion list are not printed with +.Fl C +and +.Fl D . +.It Fl e +Don't complain about files that are in the file hierarchy, but not in the +specification. +.It Fl F Ar flavor +Set the compatibility flavor of the +.Nm +utility. +The +.Ar flavor +can be one of +.Sy mtree , +.Sy freebsd9 , +or +.Sy netbsd6 . +The default is +.Sy mtree . +The +.Sy freebsd9 +and +.Sy netbsd6 +flavors attempt to preserve output compatiblity and command line option +backward compatibility with +.Fx 9.0 +and +.Nx 6.0 +respectively. +.It Fl f Ar spec +Read the specification from +.Ar file , +instead of from the standard input. +.Pp +If this option is specified twice, the two specifications are compared +to each other rather than to the file hierarchy. +The specifications will be sorted like output generated using +.Fl c . +The output format in this case is somewhat reminiscent of +.Xr comm 1 , +having "in first spec only", "in second spec only", and "different" +columns, prefixed by zero, one and two TAB characters respectively. +Each entry in the "different" column occupies two lines, one from each +specification. +.It Fl I Ar tags +Add the comma separated tags to the +.Dq inclusion +list. +Non-directories with tags which are in the inclusion list are printed with +.Fl C +and +.Fl D . +If no inclusion list is provided, the default is to display all files. +.It Fl i +If specified, set the schg and/or sappnd flags. +.It Fl j +Indent the output 4 spaces each time a directory level is descended when +creating a specification with the +.Fl c +option. +This does not affect either the /set statements or the comment before each +directory. +It does however affect the comment before the close of each directory. +This is the equivalent of the +.Fl i +option in the +.Fx +version of +.Nm . +.It Fl K Ar keywords +Add the specified (whitespace or comma separated) keywords to the current +set of keywords. +If +.Ql all +is specified, add all of the other keywords. +.It Fl k Ar keywords +Use the +.Sy type +keyword plus the specified (whitespace or comma separated) +keywords instead of the current set of keywords. +If +.Ql all +is specified, use all of the other keywords. +If the +.Sy type +keyword is not desired, suppress it with +.Fl R Ar type . +.It Fl L +Follow all symbolic links in the file hierarchy. +.It Fl l +Do +.Dq loose +permissions checks, in which more stringent permissions +will match less stringent ones. +For example, a file marked mode 0444 +will pass a check for mode 0644. +.Dq Loose +checks apply only to read, write and execute permissions -- in +particular, if other bits like the sticky bit or suid/sgid bits are +set either in the specification or the file, exact checking will be +performed. +This option may not be set at the same time as the +.Fl U +or +.Fl u +option. +.It Fl M +Permit merging of specification entries with different types, +with the last entry taking precedence. +.It Fl m +If the schg and/or sappnd flags are specified, reset these flags. +Note that this is only possible with securelevel less than 1 (i.e., +in single user mode or while the system is running in insecure +mode). +See +.Xr init 8 +for information on security levels. +.It Fl n +Do not emit pathname comments when creating a specification. +Normally +a comment is emitted before each directory and before the close of that +directory when using the +.Fl c +option. +.It Fl N Ar dbdir +Use the user database text file +.Pa master.passwd +and group database text file +.Pa group +from +.Ar dbdir , +rather than using the results from the system's +.Xr getpwnam 3 +and +.Xr getgrnam 3 +(and related) library calls. +.It Fl P +Don't follow symbolic links in the file hierarchy, instead consider +the symbolic link itself in any comparisons. +This is the default. +.It Fl p Ar path +Use the file hierarchy rooted in +.Ar path , +instead of the current directory. +.It Fl q +Quiet mode. +Do not complain when a +.Dq missing +directory cannot be created because it already exists. +This occurs when the directory is a symbolic link. +.It Fl R Ar keywords +Remove the specified (whitespace or comma separated) keywords from the current +set of keywords. +If +.Ql all +is specified, remove all of the other keywords. +.It Fl r +Remove any files in the file hierarchy that are not described in the +specification. +.It Fl S +When reading a specification into an internal data structure, +sort the entries. +Sorting will affect the order of the output produced by the +.Fl C +or +.Fl D +options, and will also affect the order in which +missing entries are created or reported when a directory tree is checked +against a specification. +.Pp +The sort order is the same as that used by the +.Fl c +option, which is that entries within the same directory are +sorted in the order used by +.Xr strcmp 3 , +except that entries for subdirectories sort after other entries. +By default, if the +.Fl S +option is not used, entries within the same directory are collected +together (separated from entries for other directories), but not sorted. +.It Fl s Ar seed +Display a single checksum to the standard error output that represents all +of the files for which the keyword +.Sy cksum +was specified. +The checksum is seeded with the specified value. +.It Fl t +Modify the modified time of existing files, the device type of devices, and +symbolic link targets, to match the specification. +.It Fl U +Same as +.Fl u +except that a mismatch is not considered to be an error if it was corrected. +.It Fl u +Modify the owner, group, permissions, and flags of existing files, +the device type of devices, and symbolic link targets, +to match the specification. +Create any missing directories, devices or symbolic links. +User, group, and permissions must all be specified for missing directories +to be created. +Note that unless the +.Fl i +option is given, the schg and sappnd flags will not be set, even if +specified. +If +.Fl m +is given, these flags will be reset. +Exit with a status of 0 on success, +2 if the file hierarchy did not match the specification, and +1 if any other error occurred. +.It Fl W +Don't attempt to set various file attributes such as the +ownership, mode, flags, or time +when creating new directories or changing existing entries. +This option will be most useful when used in conjunction with +.Fl U +or +.Fl u . +.It Fl X Ar exclude-file +The specified file contains +.Xr fnmatch 3 +patterns matching files to be excluded from +the specification, one to a line. +If the pattern contains a +.Ql \&/ +character, it will be matched against entire pathnames (relative to +the starting directory); otherwise, +it will be matched against basenames only. +Comments are permitted in +the +.Ar exclude-list +file. +.It Fl x +Don't descend below mount points in the file hierarchy. +.El +.Pp +Specifications are mostly composed of +.Dq keywords , +i.e. strings that +that specify values relating to files. +No keywords have default values, and if a keyword has no value set, no +checks based on it are performed. +.Pp +Currently supported keywords are as follows: +.Bl -tag -width sha384digestxx +.It Sy cksum +The checksum of the file using the default algorithm specified by +the +.Xr cksum 1 +utility. +.It Sy device +The device number to use for +.Sy block +or +.Sy char +file types. +The argument must be one of the following forms: +.Bl -tag -width 4n +.It Ar format , Ns Ar major , Ns Ar minor +A device with +.Ar major +and +.Ar minor +fields, for an operating system specified with +.Ar format . +See below for valid formats. +.It Ar format , Ns Ar major , Ns Ar unit , Ns Ar subunit +A device with +.Ar major , +.Ar unit , +and +.Ar subunit +fields, for an operating system specified with +.Ar format . +(Currently this is only supported by the +.Sy bsdos +format.) +.It Ar number +Opaque number (as stored on the file system). +.El +.Pp +The following values for +.Ar format +are recognized: +.Sy native , +.Sy

+See +.Xr mknod 8 +for more details. +.It Sy flags +The file flags as a symbolic name. +See +.Xr chflags 1 +for information on these names. +If no flags are to be set the string +.Ql none +may be used to override the current default. +Note that the schg and sappnd flags are treated specially (see the +.Fl i +and +.Fl m +options). +.It Sy ignore +Ignore any file hierarchy below this file. +.It Sy gid +The file group as a numeric value. +.It Sy gname +The file group as a symbolic name. +.It Sy link +The file the symbolic link is expected to reference. +.It Sy md5 +The +.Tn MD5 +cryptographic

followed by an +equals sign +.Pq Ql = , +followed by the keyword's value, without +whitespace characters. +These values override, without changing, the global value of the +corresponding keyword. +.Pp +The first path name entry listed must be a directory named +.Ql \&. , +as this ensures that intermixing full and relative path names will +work consistently and correctly. +Multiple entries for a

+it is recommended that +.Nm +be run on the file systems, and a copy of the results stored on a different +machine, or, at least, in encrypted form. +The seed for the +.Fl s +option should not be an obvious value and the final checksum should not be +stored on-line under any circumstances! +Then, periodically, +.Nm +should be run against the on-line specifications and the final checksum +compared with the previous value. +While it is possible for the bad guys to change the on-line specifications +to conform to their modified binaries, it shouldn't be possible for them +to make it produce the same final checksum value. +If the final checksum value changes, the off-line copies of the specification +can be used to detect which of the binaries have actually been modified. +.Pp +The +.Fl d +option can be used in combination with +.Fl U +or +.Fl u +to create directory hierarchies for, for example, distributions. +.Sh COMPATIBILITY +The compatibility shims provided by the +.Fl F +option

replacing them with appropriate +.Sy uid +and +.Sy gid +keywords rather than failing and reporting an error. +The related +.Fl w +flag is a no-op rather than causing a warning to be printed and no +keyword to be emitted. +The latter behavior is not emulated as it is potentially dangerous in +the face of /set statements. +.Pp +The +.Sy netbsd6 +flavor does not replicate the historical bug that
