sed script to find and replace a string of text

sed script to find and replace a string of text

(OP)
Hello
I am looking for a sed script that can search through a file and replace a string that starts with a certain letter and ends with a fulls stop for a fixed string.
For example:

Hello world, I am ronaldmacdonald.

This is the repalcement string.

So in the above I want to replace all occurrunces of the string that start with "H" and end with "." with the text "This is the repalcement string."

Is this possible?

Thanks

RE: sed script to find and replace a string of text

Hi

Like this ?

CODE --> command-line

sed 's/^H.*\.$/This is the repalcement string./' /input/file 
( If you like the above command's output, you may add a -i option to alter the input file directly. )

Yes that looks likeit would be ok, sadly I am using sed for windows which isn't as forgiving as the sed for unix so I need to tweak that up a bit but thanks.
