What command is used to display a file contents in octal form? A. oct B. of C. od D. cd E. None of the above

The correct answer is C. od.

od -t o foo.txt

This will print the contents of the file, one byte at a time, in octal.

• A. oct is not a valid command.
• B. of is a command that is used to open a file.
• D. cd is a command that is used to change the current directory.
• E. None of the above is the correct answer.
