I am trying to insert a line after a line whose value is stored in a variable $LASTLINE

sed "/$LASTLINE/a\newuser $user" $file > $file.new

This should insert a line starting with 'newuser' followed by 10 spaces and then $user the value of which the user will enter. But the above command does not work. Any help is appreciated.

Thanks

Why doesn't the command work?

Is the "user" variable set?

a is append... not insert....

Please be more specific about why the command isn't working as you'd expect.

Cheers
