Is there a way to pass variables to sed? I would like to present a user with a list with line numbers, then prompt the user for the line number that they would like to delete. I thought that I would like to use sed to delete that line, here is what I had in mind:
cat list | more
echo "Enter line number to be deleted..."
sed -e $myNumd
I know that I can do this to delete line 5
sed -e 5d
but I am having trouble passing variables. Any ideas? Or other solutions?
If you want it to put the results in the same file, of course you'll have to use cat. But for things like piping the output of cat to more, it's just unnecessary. I was just pointing out that sed can work on files directly if you want it to.
