linux sort command produces strange output
cat a
.a
ba
.b
bb
.c
bc
sort a
.a
.b
ba
bb
bc
.c
NOTE: .a and .b appears before ba and bb, where as .c appears after bc.
In general
if the file has strings of the type .<x> and <y><x>,
then for all x <= y, .x appear before yx and
for all x>y, .x appear after yx
Is this a bug or an expected behavior? It latter is the case, then what is the explanation?

Hi there,
I'm puzzled. Compressing the same file (same name, same md5sum) at two different times will produce a different output. I mean the md5sum of the resulting .gz files are different.
Does it make any sens to any of you?
I'd like some explanations if you know what's going on.
