bart_manifest - system audit manifest file
The bart(8) command generates a manifest that describes the contents of a managed host. A manifest consists of a header and entries. Each entry represents a single file. Entries are sorted in ascending order by file name. Any nonstandard file names, such as those that contain embedded newline or tab characters, have the special characters quoted prior to being sorted. See Quoting Syntax.
Lines that begin with ! supply metadata about the manifest. The manifest version line indicates the manifest specification version. The date line shows the date on which the manifest was created, in date(1) form.
Some lines are ignored by the manifest comparison tool. Ignored lines include blank lines, lines that consist only of white space, and comments that begin with #.
In addition to metadata lines, the header contains the format comment block. This comment block lists the attributes reported for each file type.
To see the format of a manifest file, see EXAMPLES.
Each manifest file entry is a single line of one of the following forms, depending on the file type:
fname D size mode acl dirmtime uid gid fname P size mode acl mtime uid gid fname S size mode acl mtime uid gid fname F size mode acl mtime uid gid contents fname L size mode acl lnmtime uid gid dest fname B size mode acl mtime uid gid devnode fname C size mode acl mtime uid gid devnode
The fields of the manifest file entries are described as follows:
Name of the file. To prevent parsing problems that are caused by special characters embedded in file names, file names are encoded as described in Quoting Syntax.
Type of file.
Possible values for type are as follows:
Block device node
Character device node
File size in bytes.
Octal number that represents the permissions of the file.
ACL attributes for the file. For a file with ACL attributes, this field contains the output from acltotext().
Numerical user ID of the owner of this entry.
Numerical group ID of the owner of this entry.
Modification time in seconds since 00:00:00 UTC, January 1, 1970 for directories.
Creation time for links.
Modification time in seconds since 00:00:00 UTC, January 1, 1970 for files.
Checksum value of the file. This attribute is only specified for regular files. If you turn off context checking or if checksums cannot be computed, the value of this field is –.
Destination of a symbolic link.
Value of the device node. This attribute is for character device files and block device files only.
The rules file supports a quoting syntax for representing nonstandard file names.
When generating a manifest for file names that embedded TAB, SPACE, or NEWLINE characters, the special characters are encoded in their octal forms.
The following is a sample system manifest file. The file entries are sorted by the encoded versions of the file names to correctly handle special characters.
