Hello,
For a file called "a" with the following contents (two lines of one
character each):
4
_
and a file called "b" with the following contents (two lines of one
character each):
5
_
I am observing the following:
comm -23 a b
4
_
comm -13 a b
5
_
comm -12 a b
But I would have expected:
comm -23 a b
4
comm -13 a b
5
comm -12 a b
_
Why does comm do this?
(I am observing this behavior in larger, more complex files where the
resulting behavior makes a difference. For expediency, I have pared
things down to show the same behavior in this simple example.)
comm (coreutils) 5.2.1
Linux 2.6.9-22.0.1.ELsmp #1 SMP Thu Oct 27 14:49:37 CDT 2005 x86_64
x86_64 x86_64 GNU/Linux
