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. 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

NAME
mkbom -- create a bill-of-materials file SYNOPSIS
mkbom [-s] directory bom mkbom [-s] -i filelist bom mkbom -h | --help DESCRIPTION
The mkbom command creates a bill-of-materials (bom(5)). You must specify either a source as a directory, or a text file containing a file listing as outputted by lsbom(8). mkbom will generate bill-of-materials information based on that information. Any existing bomfile will be overwritten by the new bomfile. Options: -h print full usage -s create a simplified bom containing only file paths -i filelist use the information in filelist, one entry per line, to construct the bom file. The format of the file should match lsbom(8) output with no formatting options (the default). If -s is given to mkbom, the input filelist should contain only pathnames, as with lsbom -s. SEE ALSO
