use variable for sed print line
I'm using the sed command to pull a line from a file and place it into another file:
sed -n '1p' students >tmp
this pulls the first line, I want to change the 1 to a variable which will be a counter to go through the rest of the lines but can't get it. I've tried:
sed -n '$cp students >tmp
sed -n $cp students >tmp
neither work. Any ideas? Thanks!

but if I replace date with the variable it seems it's not recognizing it and throwing out error
