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. SEE ALSO
ditto(1), lsbom(8), mkbom(8) 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. Mac OS X 28 September 2006 Mac OS X

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 SEE ALSO

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. Mac OS X May 7, 2008 Mac OS X
