Assignment Research the sed command and focus on various functions it can perform. Pick THREE functions of sed that edit a text file which you find most interesting. Clearly list the parameter / option you have chosen (separate them into standalone paragraphs) and USING YOUR OWN WORDS write what it does and why you think it is useful. Show specific syntax (commands with parameters and arguments) you would use to apply your chosen parameter and explain what would happen to the file if you executed this command. Note: There is a page about sed in the NetAcad (Chapter 7.14) and countless high-quality manuals online. YOU MUST NOT copy the examples from the NetAcad for this assignment (doing so will result in a zero), but rather use any resource of your choice to help you CREATE YOUR OWN EXAMPLES Site the source used for this assignment
