Hi,
this is about supporting -k/--keep, like bzip2 and xz do. (Strictly, not a bug,
just a missing feature.)
I know this was suggested several years ago by at least a few people and I
vaguely remember having seen that someone other than me provided a patch for
it. But gzip still does not support the -k option. So, is there a reason for
that?
In case there's not: Looking into the sources of version 1.4, a patch was
quickly done - attached here. It's a very simple thing and shouldn't be able to
break anything, except that I found a commented out option -k/--pkzip which I
left commented out but changed to -p/--pkzip since -p was not used otherwise.
Why it's (still) wanted: Once in a while I "test" some compressors for speed
and compression ratio: 7z, bzip2, xz, gzip. I'd like to try gzip first because
it's likely to be the fastest and would give me an overview about what I can
expect, but since it does not support -k and I obviously need the input file in
it's original state, gzip always gets the last place in the line. I guess I'm
not alone with this.
regards
Dirk
