od

Display file contents in hexadecimal, octal or printable character format optionally along with the byte offsets into the file

• Display file in octal format with the byte offsets in octal as well :

od --address-radix=o --format=o -v {{/path/to/file}}

• Display file in hexadecimal format with byte offsets in hexadecimal, 4 bytes per line with each entry 1 byte long :

od --address-radix=x --format=x1 --width=4 -v {{/path/to/file}}

• Display only printable strings of at least 5 characters long in the file along with the byte offsets in hexadecimal :

od --address-radix=x --string=5 -v {{/path/to/file}}

• Read only first {{number_of_bytes}} bytes of a file and display it in the hexadecimal format:

od --address-radix=x --format=x --read-bytes {{number_of_bytes}} -v {{/path/to/file}}

• Display file in hexadecimal format along with its character representation, also do not print byte offsets:

od --address-radix=n --format=xz -v {{/path/to/file}}
