+are ignored. +.It Special +Lines beginning with +.Cm / +are special commands that influence +the interpretation of later lines. +.It Relative +If the first whitespace-delimited word has no +.Cm / +characters, +it is the name of a file in the current directory. +Any relative entry that describes a directory changes the +current directory. +.It dot-dot +As a special case, a relative entry with the filename +.Pa .. +changes the current directory to the parent directory. +Options on dot-dot entries are always ignored. +.It Full +If the first whitespace-delimited word has a +.Cm / +character after +the first character, it is the pathname of a file relative to the +starting directory. +There can be multiple full entries describing the same file. +.El +.Pp +Some tools that process +.Nm +files may require that multiple lines describing the same file +occur consecutively. +It is not permitted for the same file to be mentioned using +both a relative and a full file specification. +.Ss Special commands +Two special commands are currently defined: +.Bl -tag -width Cm +.It Cm /set +This command defines default values for one or more keywords. +It is followed on the same line by one or more whitespace-separated +keyword definitions. +These definitions apply to all following files that do not specify +a value for that keyword. +.It Cm /unset +This command removes any default value set by a previous +.Cm /set +command. +It is followed on the same line by one or more keywords +separated by whitespace. +.El +.Ss Keywords +After the filename, a full or relative entry consists of zero +or more whitespace-separated keyword definitions. +Each such definitions consists of a key from the following +list immediately followed by an '=' sign +and a value. +Software programs reading mtree files should warn about +unrecognized keywords. +.Pp +Currently supported keywords are as follows: +.Bl -tag -width Cm +.It Cm cksum +The checksum of the file using the default algorithm specified by +the +.Xr cksum 1 +utility. +.It Cm contents +The full pathname of a file whose contents should be +compared to the contents of this file. +.It Cm 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 +.Dq none +may be used to override the current default. +.It Cm ignore +Ignore any file hierarchy below this file. +.It Cm gid +The file group as a numeric value. +.It Cm gname +The file group as a symbolic name. +.It Cm md5 +The MD5 message digest of the file. +.It Cm md5digest +A synonym for +.Cm md5 . +.It Cm sha1 +The +.Tn FIPS +160-1 +.Pq Dq Tn SHA-1 +message digest of the file. +.It Cm sha1digest +A synonym for +.Cm sha1 . +.It Cm sha256 +The +.Tn FIPS +180-2 +.Pq Dq Tn SHA-256 +message digest of the file. +.It Cm sha256digest +A synonym for +.Cm sha256 . +.It Cm ripemd160digest +The +.Tn RIPEMD160 +message digest of the file. +.It Cm rmd160 +A synonym for +.Cm ripemd160digest . +.It Cm rmd160digest +A synonym for +.Cm ripemd160digest . +.It Cm mode +The current file's permissions as a numeric (octal) or symbolic +value. +.It Cm nlink +The number of hard links the file is expected to have. +.It Cm nochange +Make sure this file or directory exists but otherwise ignore all attributes. +.It Cm uid +The file owner as a numeric value. +.It Cm uname +The file owner as a symbolic name. +.It Cm size +The size, in bytes, of the file. +.It Cm link +The file the symbolic link is expected to reference. +.It Cm time +The last modification time of the file. +.It Cm type +The type of the file; may be set to any one of the following: +.Pp +.Bl -tag -width Cm -compact +.It Cm block +block special device +.It Cm char +character special device +.It Cm dir +directory +.It Cm fifo +fifo +.It Cm file +regular file +.It Cm link +symbolic link +.It Cm socket +socket +.El +.El +.Pp +.Sh SEE ALSO +.Xr cksum 1 , +.Xr find 1 , +.Xr mtree 8 +.Sh BUGS +The +.Fx +implementation of mtree does not currently support +the +.Nm +2.0 +format. +The requirement for a +.Dq #mtree +signature line is new and not yet widely implemented. +.Sh HISTORY +The +.Nm +utility appeared in +.Bx 4.3 Reno . +The +.Tn MD5 +digest capability was added in +.Fx 2.1 , +in response to the widespread use of programs which can spoof +.Xr cksum 1 . +The +.Tn SHA-1 +and +.Tn RIPEMD160 +digests were added in +.Fx 4.0 , +as new attacks have demonstrated weaknesses in +.Tn MD5 . +The +.Tn SHA-256 +digest was added in +.Fx 6.0 . +Support for file flags was added in +.Fx 4.0 , +and mostly comes from +.Nx . +The +.Dq full +entry format was added by +.Nx . |
