Q: Partial file lines replace in linux I have a file containing some lines 
Example:
Line 1 , @A11 @A21 @A31
Line 2 , @A12 @A22 @A32
Line 3 , @A13 @A23 @A33

I have other files which lines might contain some of the lines in the above example, like: 
skip('Line X , @B11 @B21 @B31');
 code { ... }
skip('Line 1 , @A11 @A21 @A31');
 code { ... }
skip('Line Z , @C11 @C21 @C31');
 code { ... }

I want to be able to read all the lines from the first file and whenever I match line from the second example to replace 'skip(' with 'run('.
So line two from the second example should become
run('Line 1 , @A11 @A21 @A31');
