Could you please elaborate more about the GNU gzip behavior?

By the way I also found some difference between BSD gzip and GNU gzip:

touch foo
ln -s foo.nonexistent foo.gz

gzip foo
gzip: could not create output: foo.gz: File exists

/usr/local/bin/gzip foo
gzip: foo.gz already exists; do you wish to overwrite (y or n)? ^C
(case 1)

echo | /usr/local/bin/gzip foo
gzip: foo.gz already exists;	not overwritten

gzip -f foo
gzip: could not create output: foo.gz: File exists

/usr/local/bin/gzip -f foo
(succeeded; case 2).


Cheers,
