How do I make sdiff ignore the * character?

  • 772

Here's what I'm sure is an easy one, but I can't figure it out.

I have two files:

file1: You are in a maze of twisty little passages, all alike
file2: You are in a maze of twisty little* passages, all alike

I want to perform sdiff on these files, but I want to ignore the * character.

How do I do this?

regex diff

    Actually, -I will ignore the whole line I think, not the character. If you want to ignore the character you can:

    sdiff <(cat file1 | tr -d '*') <(cat file2 | tr -d '*')

    Reference from man sdiff:

    -I RE  --ignore-matching-lines=RE
              Ignore changes whose lines all match RE.
