sed -i '7 c\$variable' file ....(?!@#$%^&*!)

I have tried everything I can think of to get sed to change line N of a file to the contents of a variable. I have Googled the Internet, and I find lots of people telling how to use variables with the "Substitute" command, but no one telling how to use variables with the "Change" command.

I have considered the possibility of using the "Substitute" command with a wild card for existing text, but my search of the Internet tells me SED doesn't have wild cards in its repertoire, so it's difficult! There must be a better way.

As I noted in the subject, the basic form I used is (where N is a line number):

Code:

sed -i 'N c\$variable' FILE

Is this possible, or is there a different command that will do it? I am working in BASH scripts.

Thanks!
