gzip produces different output from the same input
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.
Thanks
Santiago

gzforce
GZFORCE(1) General Commands Manual GZFORCE(1)
NAME
gzforce - force a '.gz' extension on all gzip files
SYNOPSIS
gzforce [ name ... ]
DESCRIPTION
gzforce forces a .gz extension on all gzip files so that gzip will not compress them twice. This can be useful for files with names trun-
cated after a file transfer. On systems with a 14 char limitation on file names, the original name is truncated to make room for the .gz
suffix. For example, 12345678901234 is renamed to 12345678901.gz. A file name such as foo.tgz is left intact.
