NAME

     bom -- bill of materials

DESCRIPTION

     The Mac OS X Installer uses a file system "bill of materials" to determine which files to install, remove, or upgrade. A bill of materials,
     bom, contains all the files within a directory, along with some information about each file. File information includes: the file's UNIX per-
     missions, its owner and group, its size, its time of last modification, and so on.  Also included are a checksum of each file and information
     about hard links.

     The bill of materials for installed packages are found within the package receipts located in /Library/Receipts.

BUGS

     Mac OS X's bill of materials format is not compatible with formats from older operating systems.

HISTORY

     The bill of materials file appeared in NeXTSTEP to support installation.  The file format was updated and extended for Mac OS X 10.0.  The
     format was extended to support 64 bit file sizes with OS X 10.3.

NAME

     lsbom -- list contents of a bom file

SYNOPSIS

     lsbom [-b] [-c] [-d] [-f] [-l] [-m] [-s] [-x] [--arch archVal] [-p parameters] bom ...
     lsbom -h | --help

DESCRIPTION

     The lsbom command interprets the contents of binary bom (bom(5)) files. For each file in a bom, lsbom prints the file path and/or requested
     information.

     If no options are given, lsbom will display the output formatted such that each line contains the path of the entry, its mode (octal), and
     its UID/GID. There are slight differences in the output for plain files, directories, symbolic links, and device files as follows:

     plain files     the UID/GID is followed by the file size and a 32-bit CRC checksum of the file's contents.

     symbolic links  the UID/GID is followed by the size and checksum of the link path, and the link path itself.

     device files    the UID/GID file number is followed by the device number.

     The -p option can be used to specify a user-defined format for lsbom's output. The format string consists of one or more characters described
     below where each character represents a data type. Data types will be separated by tab characters, and each line will end with a newline
     character. One can use this mechanism to create output similar to the ls(1) command.

     The options are:

     -h 	     print full usage

     -b 	     list block devices

     -c 	     list character devices

     -d 	     list directories

     -f 	     list files

     -l 	     list symbolic links

     -m 	     print modified times (for plain files only)

     -s 	     print only the path of each file

     -x 	     suppress modes for directories and symlinks

     --arch archVal  when displaying plain files that represent Universal Mach-O binaries, print the size and checksum of the file contents for
		     the specified archVal (either "ppc", "ppc64", or "i386")

     -p parameters   print only some of the results Note: each option can only be used once:
			   c		 32-bit checksum
			   f		 file name
			   F		 file name with quotes (i.e. "/mach_kernel")
			   g		 group id
			   G		 group name
			   m		 file mode (permissions)
			   M		 symbolic file mode (i.e. "dr-xr-xr-x" )
			   s		 file size
			   S		 formatted size
			   t		 mod time
			   T		 formatted mod time
			   u		 user id
			   U		 user name
			   /		 user id/group id
			   ?		 user name/group name

EXAMPLES

     lsbom bomfile	     list the contents of bomfile

     lsbom -s bomfile	     list only the paths of the contents of the bomfile

     lsbom -f -l bomfile     list the plain files and symbolic links of the bomfiles (but not directories or devices)

     lsbom -p MUGsf bomfiles
			     list the contents of bomfile displaying only the files' modes, user name, group name, size, and filename

HISTORY

     The lsbom command appeared in NeXTSTEP as a tool to browse the contents of bom files used during installation.

     The -p flag appeared in Mac OS X 10.1 in an attempt to make lsbom's output more convenient for human beings.
