Hi Ulrich, > However, the file mom-2.2-a.tar.gz is NOT a gzipped tar file. It is just > plain tar:
$ curl -sSI http://www.schaffter.ca/mom/mom-2.2-a.tar.gz HTTP/1.1 200 OK Date: Fri, 24 Nov 2017 17:04:19 GMT Content-Type: application/x-tar Content-Length: 544493 Connection: keep-alive Server: Apache/2 Last-Modified: Fri, 24 Nov 2017 02:45:22 GMT ETag: "84eed-55eb18b3ff480" Accept-Ranges: bytes Cache-Control: max-age=14400 Expires: Fri, 24 Nov 2017 18:58:11 GMT Content-Encoding: x-gzip Age: 7568 $ I used curl(1) and wget(1) to retrieve this URL. Both gave a 544,493 B file that was gzip'd. gunzip-ing it gave a bigger tar file. Perhaps your downloader is seeing the above Content-Encoding and trying to be helpful by decompressing it for you, but not altering the saved file name? -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
