Hello,
is this the right place to ask about how to use diff?
If not please point me in the right direction.
How can I get GNU diff ignore the blank lines in the following
example?
File a:
--- cut here ---
x
do
done
--- cut here ---
File b:
--- cut here ---
x
do
done
--- cut here ---
Neither file has trailing white spaces in any line.
Using GNU diff 3.1 on Mac OS X I get:
diff -w a b
2d1
< do
3a3
> do
Same when I add various promising looking options:
diff --suppress-blank-empty -E -b -w -B -I '^[[:space:]]*$'
--strip-trailing-cr -i a b
2d1
< do
3a3
> do
What am I missing here?
diff --version
diff (GNU diffutils) 3.1
Thanks,
Robert
