    Help needed with Linux homework...


    hi, im new to the forums and to linux, and im having a bit of trouble with my Linux homework.. its not that im lazy or anything, i've read the chapter for my class 3 times, and im still stuck on these three questions. if you could please explain to me the answers, i really would appreciate that.


    1.) Write a sequence of commands or a script that demonstrates that variable expansion occurs before pathname expansion.
    __________________________________________________ ____

    2.) Explain the behavior of the following shell script:

    $ cat quote_demo
    twoliner=”This is line 1.
    This is line 2.”
    echo “$twoliner”
    Echo $twoliner

    a. How many arguments does each echo command see in this script? Explain.
    b. Redefine the IFS shell variable so that the output of the second echo is the same as the first.

    3.)The dirname utility treats its argument as a pathname and writes to standar output the path prefix – that is, everything up to but not including the last component:

    $dirname a/b/c/d
    a/b/c
    If you give dirname a simple filename (no /charcters) as an argument, dirname writes a . to standar output.
    $ dirname simple
    .

    Implement dirname as a bash function. Make sure that it behaves sensibly when given such arguments as /.
