Need some basic help
Hi everyone, I need some help! I know that this is a very simple little problem but I seem to be stuck. I was just wondering if you could show me the right way.

I basicly have to write a single line of commands (using piping) to do the following:

From the file data.txt, select all of the lines that
contain at least six consonants
and have five digits in the fifth column.

Sort these lines in reverse order according to column 3, then
select lines 65 through 87. Finally, put these lines in
normal order according to column 1 and write them to the file
output.txt (overwrite any data already in that file).

What I have right now (missing some things):

grep -i ^[^a,e,i,o,u] * [?????]* | sort -r | head -87 | tail -64 | sort > output.txt

any help would be great.
Thanks

Sorry, the forum rules say no homework problems. However, you may want to pull up the man page for sort (one obvious observation)
