|
|
- Print the hexadecimal representation of a file, replacing duplicate lines by `*`:
|
|
|
|
`hexdump {{path/to/file}}`
|
|
|
|
- Display the input offset in hexadecimal and its ASCII representation in two columns:
|
|
|
|
`hexdump -C {{path/to/file}}`
|
|
|
|
- Display the hexadecimal representation of a file, but interpret only a specific number of bytes of the input:
|
|
|
|
`hexdump -C -n {{number_of_bytes}} {{path/to/file}}`
|
|
|
|
- Verbose - no suppression by `*` on duplicate lines:
|
|
|
|
`hexdump -v {{path/to/file}}`
|
|
|
|
- Format output using printf-like format string:
|
|
|
|
`hexdump -e '{{element_format .. end_format}}' {{path/to/file}}`
