can someone help me with these problems.

the file class.txt contains the computer login and student number of the students in a class. other information also appears on each lin of the file. items are separated from each other by spaces. of all the items on any line, only the student number is 8 digits and only the computer login is alphanumeric characters followed by two digits.
it is guaranteed that the login appears before the number on any line. i need a shell command using sed that generates the file names.dat that contains lines with just student number and the login separated by one space.

write a shell script that takes data from standard input, and reports the number of lines that begin with a #, and the number of words seen. a word is anything delimited by whitespace

Since this is another homework problem of yours... I need to see what you can come up with first, at least make an effort to solve the problem. You can type
'man sed' at the prompt for a good start.

once again i have an exam tomorrow and i cant seem to answer these specific questions which are in past exam papers. i have alot of content to study and am just trying to get things done quicker.
this is on a unix system
i would not normally post these types of questions on a forum but i thought it was the best possible option in such a short manner on time

I would assume linux since that is where most BASH scripting is done

I write Bash scripts in Solaris as well as Gentoo Linux

Let me know if you still have problems with this after you run the 'man sed' command and try it out first.

Yeah but notice the forum title? BASH/Shell Scripting. Also note that there are several different types of shells.

I guess he wanted us to do it for him. lol maybe if he fails a few times he will learn to stop procrastinating.
