diff files
I have two files want to be file the difference , the format is as below
file A
======
file1.txt
file2.txt
file3.txt
"
file B
======
errorfile1.txt
errorfile2.txt
errorfile3.txt
"
the file B has the files but all files begins with "error" , if I use diff to find the difference , it should pop all three lines are different . Can advise if I want to ignore this kind of difference , that mean if the line in file B is begins with the "error" , that treat this is no difference ( then do not output the difference to screen) , only check other
difference of both files , what can i do ? thx
