![]() ![]() xxd command is a little special in the sense, apart from displaying the hex contents of a file, it can also do the reverse conversion as well(-r). The last one is a very rarely used command, xxd. ![]() To make this output more readable, use the "-c" option :Ä£. However, the od command also has options(-x) to do the hex dump of a file and the output is in big endian format: Another command, od, is quite frequently used in Unix world for octal dump of a file.
