I hope you can read it carefully and be able to achieve something!

In the Linux system, the od command is mainly used to output the contents of the file. After executing the command, the contents of the given file will be read and presented in octal code.

Syntax od [- abcdfhilovx] [- A] [- j] [- N] [- s] [- t] [- w] [--help] [--version] [file.] Parameter:-a this parameter has the same effect as specifying the "- ta" parameter at the same time.

-A chooses what cardinality to calculate the word code.

-b the effect of this parameter is the same as specifying the "- toC" parameter at the same time.

-c the effect of this parameter is the same as specifying the "- tC" parameter at the same time.

-d this parameter has the same effect as specifying the "- tu2" parameter at the same time.

-f this parameter has the same effect as specifying the "- tfF" parameter at the same time.

-h this parameter has the same effect as specifying the "- tx2" parameter at the same time.

-I this parameter has the same effect as specifying the "- td2" parameter at the same time.

The number of characters set by-j or-skip-bytes= skipped.

-l this parameter has the same effect as specifying the "- td4" parameter at the same time.

-N or-read-bytes= up to the set number of characters.

-o this parameter has the same effect as specifying the "- to2" parameter at the same time.

-s or-strings= displays only strings that match the specified number of characters.

-t or-format= sets the output format.

Duplicate data is not omitted when-v or-output-duplicates is output.

-w or-width= sets the maximum number of characters per column.

-x the effect of this parameter is the same as specifying the "- h" parameter at the same time.

-help online help.

-version displays version information.
