A modern alternative to `xxd` and `hexdump`
Quick install
requirements: Go 1.20+ (it may build with earlier versions as well but I have not tested them) and git
git clone https://github.com/sweetbbak/hexxy && cd hexxy
go build
On ArchLinux (hexxy-git), e.g.:
pikaur -S hexxy-git
Example usage
# normal usage
hexxy /path/to/file.bin
# output without color
hexxy --no-color /path/to/file.bin
# read from stdin
cat mybinary | hexxy
# display plain output
hexxy -p file.bin
# Include a binary as a C variable
hexxy -i input-file > output.c
# Use plain non-formatted output
hexxy -p input-file
# crunch empty lines with a '*' and use uppercase HEX
hexxy -a --upper input-file
# Reverse plain non-formatted output (reverse plain)
hexxy -rp input-file
# Show output with a space in between N groups of bytes
hexxy -g1 input-file ... -> outputs: 00000000: 0f 1a ff ff 00 aa
# display offset in Decimal format
hexxy -td file.bin
# display offset in Octal format
hexxy -to file.bin

thanks to felixge for showing how this is done quickly thanks to igoracmelo for the idea to colorize hexdump output with a gradient
