    Sed is a stream text editor used at the command line. Sed allows you to edit text files on a line-by-line basis. The typical sed command syntax is:
    Code:
    set "editing-command" filename
    By default, when you use the sed command it will print all lines of a document after they have been processed (In this case, the term "print" refers to the standard output on the screen). This can be cumbersome if the document is long. Of the options below, which commands can you issue with sed to suppress the output of sed only prints those lines you have specified for printing? Select three answers.

    1. --suppress
    2. --silent
    3. --quiet
    4. -n
    5. -s
    6. -q

    Answer later.

    I'd guess at 2, 3 and 6. No experience of sed whatsoever...

    I'll guess 4 as my sed experience is pretty limited, but from my reading I seem to remember something about -n.

    Answer time. Guess I'll have to give partial credit to the both of you. The correct answers are 2, 3, and 4: --silent, --quiet, and -n.

    Also, I made a mistake when I posted the question. I typed the word "set" when describing the syntax instead of "sed". :oops:
