mkbom

MKBOM(8)						    BSD System Manager's Manual 						  MKBOM(8)

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

     bom(5), ditto(8), mkbom(8)

HISTORY

     The mkbom command appeared in NeXTSTEP as a tool to create bom files used during installation.
