"For the following and any subsequent exercises you ARE NOT permitted to use either SED or AWK".

Script 1

Pre-requisites
Create a file with x amount of lines in it, the content of your choice.

Write a script that takes two arguments. The first being a line of text, the second being your newly created file. The script should take the first argument and insert it into the very top (the first line) of the file named in your second argument.

Note! The file must retain the original name

to take in arguments, you can use $1, $2 etc. $1 being the first argument, $2 the second and so on. your teacher should have taught you this before he asked you to do homework. you can use echo $1 >> $2 to insert a line into $2, which is your file name.
i believe you can start writing the script now.

if i do in this way $1>>$2 the line of text would go at the end of the file and not on the top of the file.
how about f i use -ed- editor?
