I have a number of gzip archives; however they have a zip extension not gz:
***.zip
When I try to unzip them with unzip, I get not a zip archive error, and with gunzip I get unknown suffix: zip
What is going on here really?
zip gzip

By default, gzip will only decompress files with extensions from a limited list—rather than examining the file magic to determine if it is a gzip'd file. From a comment in gzip.c:get_suffix():
/* ========================================================================
* Return a pointer to the 'z' suffix of a file name, or NULL. For all
* systems, ".gz", ".z", ".Z", ".taz", ".tgz", "-gz", "-z" and "_z" are
* accepted suffixes, in addition to the value of the --suffix option.
To use input files which are in fact gzip'd but are not named following gzip's expected conventions, provide the suffix explicitly as per the gzip manual page:
-S .suf --suffix .suf
... When decompressing, add .suf to the beginning of the list of suffixes to try, when deriving an output file name from an input file name.
$ gunzip -S .zip foo.zip
or use redirection to prevent gzip from seeing the filename:
$ gunzip < foo.zip > foo.txt

+1 for a cause - but why notcat file.zip | gunzip > file.extfor the quick lazy way of doing it? And ifcatwill interrupt due to the "special" characters that would show in a binary, wouldddwork in its place -dd if=filezame.zip | gunzip > filename.ext
