I would like to point out a bug that has already been reported last year [1].
Observed behaviour: $ echo foo > test $ gzip --suffix z test $ ls testz testz $ gzip -d --suffix z testz gzip: testz: unknown suffix -- ignored Expected behaviour: $ gzip -d --suffix z testz $ ls test test From the comment in function get_suffix I gather that the "z" suffix is overlooked in the sequence of suffixes to try. I've attached a patch that makes it work for me. [1] http://lists.gnu.org/archive/html/bug-gzip/2013-07/msg00012.html Kind regards, Sam
