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

ls - list contents of directory SYNOPSIS
ls [ -acdfgiloqrstu1ACLFR ] name ... DESCRIPTION
For each directory argument, ls lists the contents of the directory; for each file argument, ls repeats its name and any other information requested. By default, the output is sorted alphabetically. When no argument is given, the current directory is listed. When several arguments are given, the arguments are first sorted appropriately, but file arguments are processed before directories and their contents. There are a large number of options: -l List in long format, giving mode, number of links, owner, size in bytes, and time of last modification for each file. (See below.) If the file is a special file the size field will instead contain the major and minor device numbers. If the file is a symbolic link the pathname of the linked-to file is printed preceded by ``->''. -o Include the file flags in a long (-l) output. -g Include the group ownership of the file in a long output. -t Sort by time modified (latest first) instead of by name. -a List all entries; in the absence of this option, entries whose names begin with a period (.) are not listed. -s Give size in kilobytes of each file. -d If argument is a directory, list only its name; often used with -l to get the status of a directory. -L If argument is a symbolic link, list the file or directory the link references rather than the link itself. -r Reverse the order of sort to get reverse alphabetic or oldest first as appropriate. -u Use time of last access instead of last modification for sorting (with the -t option) and/or printing (with the -l option). -c Use time of file creation for sorting or printing. -i For each file, print the i-number in the first column of the report. -f Output is not sorted. -F cause directories to be marked with a trailing `/', sockets with a trailing `=', symbolic links with a trailing `@', and executable files with a trailing `*'. -R recursively list subdirectories encountered. -1 force one entry per line output format; this is the default when output is not to a terminal. -C force multi-column output; this is the default when output is to a terminal. -q force printing of non-graphic characters in file names as the character `?'; this is the default when output is to a terminal. The mode printed under the -l option contains 11 characters which are interpreted as follows: the first character is d if the entry is a directory; b if the entry is a block-type special file; c if the entry is a character-type special file; l if the entry is a symbolic link; s if the entry is a socket, or - if the entry is a plain file. The next 9 characters are interpreted as three sets of three bits each. The first set refers to owner permissions; the next refers to per- missions to others in the same user-group; and the last to all others. Within each set the three characters indicate permission respec- tively to read, to write, or to execute the file as a program. For a directory, `execute' permission is interpreted to mean permission to search the directory. The permissions are indicated as follows: r if the file is readable; w if the file is writable; x if the file is executable; - if the indicated permission is not granted. The group-execute permission character is given as s if the file has the set-group-id bit set; likewise the user-execute permission charac- ter is given as s if the file has the set-user-id bit set. The last character of the mode (normally `x' or `-') is t if the 1000 bit of the mode is on. See chmod(1) for the meaning of this mode. When the sizes of the files in a directory are listed, a total count of blocks, including indirect blocks is printed. FILES
/etc/passwd to get user id's for `ls -l'. /etc/group to get group id's for `ls -g'. BUGS
Newline and tab are considered printing characters in file names. The output device is assumed to be 80 columns wide. The option setting based on whether the output is a teletype is undesirable as ``ls -s'' is much different than ``ls -s | lpr''. On the other hand, not doing this setting would make old shell scripts which used ls almost certain losers. 3rd Berkeley Distribution December 20, 1994 LS(1)
