程序介绍：
The program can read a file or input stream and output its hexadecimal value to other file or standrad output, \"-b\" option set the read mode to binary, as follows:
<command> | bytes [-b] [-o <outputfile>]
<inputfile> > bytes [-b] [-o <outputfile>]
bytes <inputfile> [-b] [-o <outputfile>]
Alternatively, use the bytes command to perform interactive input and output, as shown below:
bytes [-b] [-o <outputfile>]
