Use sed to edit string in multiple files not contained in current directory
 

Hello,

I have the following problem:

CASE_FOLDER
----------->0_FOLDER
-------------------->ForceX ForceY ForceZ
----------->1_FOLDER
----------->2_FOLDER
---more folders---

The 3 Force* files contained in all folders (1,2,3..._FOLDER) have the following string skin:012 which I would like to change to skin_abc.
My plan was to use sed to edit the files in the following way:
sed 's/skin:.../skin_abc/g' $(find . -name Force*)
This seems to do what I want except that the output prints to the terminal. How can the substitution be incorporated in the files themselves rather simply the output to the screen?

Cheers,
Dylan

Fixed it!
 

Of course 5mins after I post a question I figure out what I was missing.
"-i" made the changes occur in the files themselves, i.e.

sed -i 's/skin:.../skin_abc/g' $(find . -name Force*)

Hopefully this is useful for someone else.

Cheers,
Dylan
