User Commands HEXDUMP(1) NAME hexdump - dump a file to stdout in CP/M-like hexadecimal format SYNOPSIS hexdump [-V] [-w] [-e] [-c] [-g] [-s] [_f_i_l_e_n_a_m_e...] DESCRIPTION This program provides a facility for obtaining a dump of a binary file to stdout. The default format is a CP/M style haxadecimal dump with byte offset in file, 16 bytes of hex and 16 bytes of alpha representation with '.' for non- printables per line. If no filename is given, hex reads from standard input. The program accepts the following options to control its output: -w set # of bytes dumped per line (default is 16) -e display EBCDIC character assignments rather than ASCII -c display printable characters as text in-line -g don't output mid-page gutter -s dump file section --V print version number and exit The command line is scanned left-to-right for filenames and options, and each file dumped according to the format defined by preceding options. To turn off an option, precede the letter with a +. Options that take arguments may have them immediately following the option letter or whitespace- separated. If the command-line arguments include two or more filenames (with - being regarded as a `filename' for standard input), hexdump will emit a one-line header giving the name of the file in front of each input file. The -s option expects a start offset, optionally followed by a comma-separated count. Each of these should be a decimal or hexadecimal integer (hexadecimal must be prefixed by x or h; leading zeros will be ignored). The -w option expects a width, formatted as a single decimal or haxadecimal number in the style of an -s option argument. Odd widths turn on the -g option. NOTE The definition of EBCDIC used is IBM's ASCII-compatible 96- character SCS set used with Systems Network Architecture (SNA). AUTHOR Eric S. Raymond .
