[Wolves] Sed help.

[Simon C. Burke]

I have a text file with some 18000 lines and i need to ammend something to the start and end. For the end I have: 

sed 's/$/Add Text to end"/g' myfile 

However the text I'm adding is: 

' |grep -vir 'http://' >> test.txt 


The issue I have is that how do I now escape the pipe and inverted comma's? 

Any idea's??
