NAME
tinyxxd - A hexadecimal, binary, and ASCII dump utility with color support
SYNOPSIS
tinyxxd [options] [infile [outfile]]
tinyxxd -r [-s [-]offset] [-c cols] [-ps] [infile [outfile]]
DESCRIPTION
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.
OPTIONS
- -a | -autoskip
-
Toggle autoskip mode. In this mode, a single `*` replaces lines that consist only of zeros. Default is off.
- -b | -bits
-
Output a binary digit dump instead of hexadecimal. This option is incompatible with -ps.
- -c cols | -cols cols
-
Format the output to include cols octets per line. Default is 16 (12 in C include style, 30 in PostScript).
- -C | -capitalize
-
Capitalize variable names in C include file style (-i).
- -d
-
Show the offset in decimal instead of hexadecimal.
- -e
-
Create a little-endian dump. This option is incompatible with -ps, -i, and -r.
- -g bytes | -groupsize bytes
-
Group output into octets of bytes size in the normal output mode. Default is 2 (4 for little-endian).
- -E | -EBCDIC
-
Display the characters in EBCDIC encoding instead of ASCII.
- -h | -help | --help
-
Print a summary of the options.
- -i | -include
-
Output in C include file style.
- -l len | -len len
-
Stop after len octets.
- -n name | -name name
-
Set the variable name used in C include output (-i).
- -o offset
-
Add offset to the displayed file position.
- -p | -ps | -postscript | -plain
-
Output in PostScript plain hexdump style.
- -r | -revert
-
Reverse operation: convert (or patch) hexdump into binary.
- -R when
-
Colorize the output. when can be 'always', 'auto', or 'never'. Default: 'auto'.
- -s [+][-]seek
-
Start at seek bytes absolute (or relative, with + prefix) in the input file. When used with -r, the offset is added to file positions found in the hex dump.
- -t
-
Append a terminating NUL byte to the array in C include file style (-i).
- -u
-
Use uppercase letters for hexadecimal output. Default is lowercase.
- -v | -version
-
Show version information.
EXAMPLES
- Create a standard hex dump with color:
-
tinyxxd file.bin
- Create a little-endian hex dump:
-
tinyxxd -e file.bin
- Output in binary digit format:
-
tinyxxd -b file.bin
- Create a C include file:
-
tinyxxd -i file.bin > file.h
- Reverse a hex dump into binary:
-
tinyxxd -r dump.hex > file.bin
EXIT STATUS
0 - Success. 1-5 - Various errors (e.g., file I/O errors, invalid arguments).
ENVIRONMENT VARIABLES
- NO_COLOR
-
If set, disables color output.
CAVEATS
- 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.
- 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.
