NAME
mtree - map a directory hierarchy
SYNOPSIS
mtree [-cderux] [-f spec] [-p path]
DESCRIPTION
The utility mtree compares a directory hierarchy against a specification
for a directory hierarchy. By default, the specification is read from
the standard input. Mtree verifies that the tree rooted in the current
directory matches the specification.
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.
The options are as follows:
-c Print a specification for the tree to standard output.
-d Ignore everything except directory type files.
-e Don't object to files that are in the tree but not in the
specification.
-f Read the specification from file, instead of from standard input.
-p Traverse the tree rooted in path, instead of the current directory.
-r Remove any files in the tree that are not described in the
specification.
-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.
-x Don't descend below any mount points.
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.
Currently supported keywords are as follows:
cksum The checksum of the file using the algorithm specified by the
program cksum(1).
ignore Causes the hierarchy below the file to be ignored.
group The group of the file; may be either numeric or symbolic.
mode The current file's permissions as an absolute (octal) or
symbolic value (see chmod(1)).
nlink The number of hard links the file is expected to have.
owner The owner of the file; may be either numeric or symbolic.
size The size, in bytes, of the file.
link The file a symbolic link is expected to reference.
time The last modification time of the file.
type The type of the file; may be set to any one of the following:
block block special device
char character special device
dir directory
fifo fifo
file regular file
link symbolic link
socket socket
There are four types of lines in a specification.
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.
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.
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.
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.
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 ``..'' causes the current directory path to ascend one level.
Empty lines and lines whose first non-whitespace character is a hash mark
(``#'') are ignored.
Mtree exits with a status of 0 on success and >0 if an error occurred or
the tree did not match the specification.
FILES

BUGS
The cksum keyword is not yet implemented.
The time keyword should be specifiable in human readable terms.
