.Sh SYNOPSIS
|
|
.Nm mtree
|
|
.Op Fl cderux
|
|
.Op Fl f Ar spec
|
|
.Op Fl p Ar path
|
|
.Sh DESCRIPTION
|
|
The utility
|
|
.Nm mtree
|
|
compares a directory hierarchy against a specification for a
|
|
directory hierarchy.
|
|
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

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