LSBOM(8)

NAME
lsbom

SYNOPSIS
lsbom [-bcdflmsx] [-arch archVal] [-p parameters] bom ...

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 datatype. Datatypes wil 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:

-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 fat mach-o binaries, print the size and checksum of the file contents for the specified archVal (either "ppc" 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 (ie "/usr/bin/lsbom")
    g   group id
    G   group name
    m   file mode (permissions)
    M   symbolic file mode (ie "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

BUGS
lsbom will not read bom files generated on operating systems prior to Mac OS X.

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.
