To my knowledge, \n doesn't work in sed. But you can spilt lines:
Code:
#!/bin/bash echo "This is a test sentence" | \ sed -n 's/This is\(.*\)/This is\ \1/p' => This is\(.*\) Searchpatern. => This is\ => \1 Output patern. The \ after is is there for the linebreak, the \1 prints all that was captured with the \(.*\).
