tinyxxd - A hexadecimal, binary, and ASCII dump utility with color support

tinyxxd [options] [infile [outfile]]

tinyxxd -r [-s [-]offset] [-c cols] [-ps] [infile [outfile]]

tinyxxd is a versatile utility for creating hex, binary, and ASCII dumps from binary files. It can also reverse these dumps back into binary form. Additionally, it supports various output formats, including C include files and PostScript. tinyxxd enhances readability by optionally colorizing the output, respecting the NO_COLOR environment variable.

Toggle autoskip mode. In this mode, a single `*` replaces lines that consist only of zeros. Default is off.
Output a binary digit dump instead of hexadecimal. This option is incompatible with -ps.
Format the output to include cols octets per line. Default is 16 (12 in C include style, 30 in PostScript).
Capitalize variable names in C include file style (-i).
Show the offset in decimal instead of hexadecimal.
Create a little-endian dump. This option is incompatible with -ps, -i, and -r.
Group output into octets of bytes size in the normal output mode. Default is 2 (4 for little-endian).
Display the characters in EBCDIC encoding instead of ASCII.
Print a summary of the options.
Output in C include file style.
Stop after len octets.
Set the variable name used in C include output (-i).
Add offset to the displayed file position.
Output in PostScript plain hexdump style.
Reverse operation: convert (or patch) hexdump into binary.
Colorize the output. when can be 'always', 'auto', or 'never'. Default: 'auto'.
When used after -r: revert with offset added to file positions found in hex dump.
Start at seek bytes absolute or relative (with \+ for relative offset).
Use uppercase letters for hexadecimal output. Default is lowercase.
Show version information. 

tinyxxd file.bin
tinyxxd -e file.bin
tinyxxd -b file.bin
tinyxxd -i file.bin > file.h
tinyxxd -r dump.hex > file.bin

0 - Success. 1-5 - Various errors (e.g., file I/O errors, invalid arguments).

If set, disables color output.

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.
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.
