8/19    Shell script gurus please help.  I need to strip the first 10 lines
        and the last 3 lines off a whole bunch of files.  Is there an easy
        way to use sed to do this?  Thanks.
        \_ Sounds like a trivial job for head and tail.
           \_ It is: cat foo | tail -n +10 | tail -r | tail +4 | tail -r
           \_ Not completely trivial.  You'd need a wc in there somewhere.
              head needs a +<number> functionality.
              \_ Suppose you also have GNU tac:
                        head +10 | tac | head +3 | tac
              \_ Why the wc? head -n 10, tail -3? --dim
                 should work.  -- schoen
        \_ perl.
                \-there is a fairly evil way to do it in sed [first 10 lines
        is easy] last 3 is somewhat evil. not a good idea to do in sed unless
        like at least a 3rd level sed user. if you explain better what you
                \_ I still need 23 exp to make 3rd level.
        want i can probably five you the incantation ... do you want to SEE
        the first 10 and last 3 or do you want to delete them and write the
        file back with the first 10 gone and the bottom 3 gone. also, if you
        are operating on a bunch of files, the sed line count will continue
        across files ... so you have to operate on them one at a time.
        using tac is even more begging the question than saying "ues perl".
        using head/tail is cheeseball, just like "cut" is cheeseball [i use
        cut a lot but i at least know it is cheeseball.]. this is actually
        probably something you want to do inperl because writing the "error
        checks" [what if it is a 5 line file] is simpler in pl. --psb, 18th
        level sed mage.
        \_ sed, yucky.  awk, yucky.  perl, good.
                                        \-Don't be too proud of this
        technological terror you've compiled. The abilities of perl are
        insignificant next to the power of Emacs. --parth vader

                \_ Oh yeah?  Let's see you grab the first 10 and last 3 lines
                   of a list of files in emacs from the command line.
                \_ I need the files without the first 10 lines and the
                   last 3 lines.  BTW, "head +3" doesn't work. head does
                   NOT take "+" parameters.  Thanks a lot mighty psb.
