# xxd
> Create a hexdump from a binary file or vice-versa.
- Generate a hexdump from a binary file and display the output to console:
`xxd {{input_file}}`
- Send the hexdump output to a file:
`xxd {{input_file}} {{output_file}}`
- Format output in columns of 8 octets per line:
`xxd -c {{8}} {{input_file}}`
- Display in plain hex format without any gaps:
`xxd -p {{input_file}}`
- Revert a plaintext hex into binary and store it in an output file:
`xxd -r -p {{input_file}} {{output_file}}`
