It can also reverse these dumps back into binary form. Additionally, it supports various output formats, including C include files and PostScript. .B tinyxxd enhances readability by optionally colorizing the output, respecting the NO_COLOR environment variable. .sp .SH OPTIONS .TP .B \-a | \-autoskip Toggle autoskip mode. In this mode, a single `*` replaces lines that consist only of zeros. Default is off. .TP .B \-b | \-bits Output a binary digit dump instead of hexadecimal. This option is incompatible with \-ps. .TP .B \-c cols | \-cols cols Format the output to include cols octets per line. Default is 16 (12 in C include style, 30 in PostScript). .TP .B \-C | \-capitalize Capitalize variable names in C include file style (\-i). .TP .B \-d Show the offset in decimal instead of hexadecimal. .TP .B \-e Create a little-endian dump. This option is incompatible with \-ps, \-i, and \-r. .TP .B \-g bytes | \-groupsize bytes Group output into octets of bytes size in the normal output mode. Default is 2 (4 for little-endian). .TP .B \-E | \-EBCDIC Display the characters in EBCDIC encoding instead of ASCII. .TP .B \-h | \-help Print a summary of the options. .TP .B \-i | \-include Output in C include file style. .TP .B \-l len | \-len len Stop after len octets. .TP .B \-n name | \-name name Set the variable name used in C include output (\-i). .TP .B \-o offset Add offset to the displayed file position. .TP .B \-p | \-ps | \-postscript | \-plain Output in PostScript plain hexdump style. .TP .B \-r | \-revert Reverse operation: convert (or patch) hexdump into binary. .TP .B \-R when Colorize the output. when can be 'always', 'auto', or 'never'. Default: 'auto'. .TP .B \-seek offset When used after \-r: revert with offset added to file positions found in hex dump. .TP .B \-s [+][-]seek Start at seek bytes absolute or relative (with \\+ for relative offset). .TP .B \-u Use uppercase letters for hexadecimal output. Default is lowercase. .TP .B \-v | \-version Show version information. .sp .SH EXAMPLES .TP .B Create a standard hex dump with color: .nf tinyxxd file.bin .fi .TP .B Create a little-endian hex dump: .nf tinyxxd \-e file.bin .fi .TP .B Output in binary digit format: .nf tinyxxd \-b file.bin .fi .TP .B Create a C include file: .nf tinyxxd \-i file.bin > file.h .fi .TP .B Reverse a hex dump into binary: .nf tinyxxd \-r dump.hex > file.bin .fi .sp .SH EXIT STATUS .B 0 \- Success. .B 1-5 \- Various errors (e.g., file I/O errors, invalid arguments). .sp .SH ENVIRONMENT VARIABLES .TP .B NO_COLOR If set, disables color output. .sp .SH CAVEATS .TP .B Little-endian dumps The \-e option only affects the hexadecimal representation and not the ASCII (or EBCDIC) characters on the right side of the dump. The option is incompatible with \-r, \-p, or \-i. .TP .B Reverse Operation (\-r) The reverse operation may encounter difficulties with lines that are not formatted as expected. It will skip over non-conforming lines and continue processing. Line numbers are used for positioning when writing output, so the order and completeness of lines are important. .sp .SH BUGS No known bugs so far.
