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! |
