Let's see if others chime in about whether > this usage would justify changing the behavior of gzip -k. We have decades of history across gzip, bzip2 and xz for the current semantics of -k. Generally, we have an obligation to try hard to avoid changing semantics of existing options. I.e., we have to weigh "what could go wrong?" against "what would be improv= ed?" In this case, the weights are small on each side. That alone argues against making a semantics-changing modification to such a tool. To compress a single file and keep the original, one can always read it via standard input. To summarize, while tempting to make the change, it feels like too small a gain to justify changing semantics in a tool like gzip.

If plain { gzip b; } succeeded, we have a problem because [a] is compressed=

The appending redirection operator has nothing to do with gzip. It is a sh=
ell=20
feature. If you need to protect dumb users from themselves, you need to des=
ign=20
and implement { sh -o noclobberlinks; }.

My normal usage of (hard) links is as follows:
Create a file page.txt. Link it to page.html.
Want to view? Open page.html.
Want to edit? Open page.txt.
Want to attach? gzip -k page.html =E2=80=A6 oops.

That would silently replace an existing target, which is bad.

How bad can that be? ;-)

There is a safety reason to fail. A naive user might do this:
gzip -k b && gzip -cd b.gz >b
which would trash the hard-linked file as well.
There's a similar safety issue with symbolic links:
$ ln -s a b
$ touch a
$ gzip -k b && gzip -cd b.gz >b
gzip: b: Too many levels of symbolic links
where gzip's failure prevents the naive user from trashing the linked-to=20
file.
Of course one can use -f to go ahead and compress anyway.
Similar diagnostics say "file ignored" or "ignored", and that is clearer=20
than saying "unchanged", so I installed the attached patch.

Subject: [PATCH] gzip: clarify "other links" diagnostic
* gzip.c (treat_file): Instead of saying
"gzip: FOO has 1 other link -- unchanged", say
"gzip: FOO has 1 other link -- file ignored".
This is clearer when -k is also used (Bug#50097).

The command { gzip b; } fails because it would compress [a] without renaming
it.
The command { gzip -k b; } would not compress [a], so there is no reason to
fail.

It is not the -k flag that disallows this.

Yeap, but the same happens if you run this instead: gzip b (i.e. without
-k).
It is not the -k flag that gets in the way. This is what happens in
gzip, even without using the flag.
Am I missing something?

I think the point of Krzysztof is that the patch is incomplete because, in
addition to keep the original file, it should also allow the (de)compression
of links without forcing the user to type also '-f' for no apparent reason.
$ touch a && ln a b && ls -go *

Exactly, the original file is unaffected, therefore nothing to fix in
this specific patch. Note the same happens without "-k" too.
If this is a bug, please report with the regular methods. Don't revive
this unrelated thread from the mailing list :)
