xxd

Create a hexadecimal representation (hexdump) from a binary file, or vice-versa. More information: https://manned.org/xxd.

• Generate a hexdump from a binary file and display the output:
  xxd {{input_file}}
• Generate a hexdump from a binary file and save it as a text file:
  xxd {{input_file}} {{output_file}}
• Display a more compact output, replacing consecutive zeros (if any) with a star:
  xxd -a {{input_file}}
• Display the output with 10 columns of one octet (byte) each:
  xxd -c {{10}} {{input_file}}
• Display output only up to a length of 32 bytes:
  xxd -l {{32}} {{input_file}}
• Display the output in plain mode, without any gaps between the columns:
  xxd -p {{input_file}}
• Revert a plaintext hexdump back into binary, and save it as a binary file:
  xxd -r -p {{input_file}} {{output_file}}
