I am trying to use the sed command in a script. I need to make the command something like this:
sed -i 's,text-to-replace,variable-to-replace-it-with,g' file-to-do-this-in.txt
I have tried things like: sed -i 's,text,'$variable',g' file.txt and it says there is an incomplete 's' command. Can anybody help? Please ask for clarification if needed.

Never mind, I figured it out. The solution was: sed 's/text/'$variable'/g' file.txt if anybody is interested.

Ok, slightly different problem with sed. I need to do this:
sed -i 's|'$(grep 'text' /file to look in)'|'$(grep 'text' /different file to look in)'|g' /file to do this in
Whenever I try to run this command, it says "unterminated `s' command".
Help anyone?

I think the problem is with your single quotation marks. The interpreter reads what's between the two first ones, as in:
sed -i 's|'
Try removing all single quotation marks except the first and last.

If I take away the single quotation marks around the variables, it doesn't recognize them as variables anymore. Just text.

It doesn't recognize the variables that way either.

Try using all double quotations.

Nope, still doesn't work. It recognizes the variables but gives the "unterminated `s' command" error.
