By default, the specification is read from the standard input. .Nm Mtree verifies that the tree rooted in the current directory matches the specification. .Pp Messages are written to standard output for any files whose characteristics do not match those of the specification, or which are missing from either the specification or the tree. .Pp The options are as follows: .Bl -tag -width flag .It Fl c Print a specification for the tree to standard output. .It Fl d Ignore everything except directory type files. .It Fl e Don't object to files that are in the tree but not in the specification. .It Fl f Read the specification from .Ar file , instead of from standard input. .It Fl p Traverse the tree rooted in .Ar path , instead of the current directory. .It Fl r Remove any files in the tree that are not described in the specification. .It Fl u Modify the owner, group, and permissions of existing files to match the specification, as well as create any missing directories. Owner, group, and permissions must all be specified for missing directories to be created. .It Fl x Don't descend below any mount points. .El .Pp Specifications are mostly composed of ``keywords'', i.e. strings that that specify values relating to files. No keywords have default values, and if a keyword has no set value no checks based on it are performed. .Pp Currently supported keywords are as follows: .Bl -tag -width Cm .It Cm cksum The checksum of the file using the algorithm specified by the program .Xr cksum 1 . .It Cm ignore Causes the hierarchy below the file to be ignored. .It Cm group The group of the file; may be either numeric or symbolic. .It Cm mode The current file's permissions as an absolute (octal) or symbolic value (see .Xr chmod 1 ) . .It Cm nlink The number of hard links the file is expected to have. .It Cm owner The owner of the file; may be either numeric or symbolic. .It Cm size The size, in bytes, of the file. .It Cm link The file a 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: .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 There are four types of lines in a specification. .Pp The first type of line sets a ``global'' value for a keyword, and consists of a leading ``/set'' followed by whitespace, followed by sets of keyword/value pairs, separated by whitespace. Keyword/value pairs consist of a keyword, followed by a equals sign (``=''), followed by a value, without intervening whitespace. Once a keyword has been set, its value remains unchanged until either set again or unset. .Pp The second type of line unsets keywords and consists of a leading ``/unset'', followed by whitespace, followed by one or more keywords, separated by whitespace. .Pp The third type of line is a file specification and consists of a file name, followed by whitespace, followed by zero or more whitespace separated keyword/value pairs. The file name may be preceded by any number of whitespace characters. The file name may contain any of the standard file name matching characters (``['', ``]'', ``?'' or ``*''), in which case files in the hierarchy will be associated with the first pattern that they match. .Pp Each of the keyword/value pairs consist of a keyword, followed by an equals sign (``=''), followed by the keyword's value, without intervening whitespace. These values override, without changing, the global value of the corresponding keyword. .Pp All paths are relative. Specifying a directory will cause subsequent files to be searched for in that directory hierarchy. Which brings us to the last type of line in a specification: a line containing only the string .Dq Nm \&.. causes the current directory path to ascend one level. .Pp Empty lines and lines whose first non-whitespace character is a hash mark (``#'') are ignored. .Pp .Nm Mtree exits with a status of 0 on success and >0 if an error occurred or the tree did not match the specification. .Sh FILES .Bl -tag -width /etc/mtree -compact .It Pa /etc/mtree system specification directory .El .Sh SEE ALSO .Xr chmod 1 , .Xr chown 1 , .Xr chgrp 1 , .Xr cksum 1 , .Xr find 1 , .Xr stat 2 , .Xr fts 3 , .Xr mkproto 8 .Sh BUGS The .Cm cksum keyword is not yet implemented. .Pp The .Cm time keyword should be specifiable in human readable terms. .Sh EXAMPLE .Bd -literal -offset indent -compact # fs: /a/staff/rick/mybin # by: rick # date: Fri May 25 12:26:57 1990 /set group=staff mode=0555 nlink=1 owner=rick type=file [ nlink=2 size=6144 adb size=53248 df group=operator mode=02555 size=20480 ps group=kmem mode=02555 size=54272 rcp owner=root mode=04555 size=79872 test nlink=2 size=6144 /set group=wheel mode=0444 nlink=1 owner=rick type=file manpages type=dir mode=0775 nlink=2 size=1024 adb.man size=9473 df.man size=5263 tar.man size=3324 \&.. .Ed .Sh HISTORY The .Nm mtree utility appeared in .Bx 4.3 Reno .
