Fraser TweedaleWithout the '-n' ('--no-name') argument, gzip includes a timestamp in output which results in different files. Important systems like FreeBSD ports and perhaps several others hash/checksum downloaded files to ensure integrity. For projects that do not release official archives, gitweb's snapshot feature would be an excellent alternative, except that the files it produces are not identical.
Whilst '--no-name' is more descriptive, the long version of the flag is not supported on all systems. In particular, OpenBSD does not appear to support it.
Supply '-n' to gzip to exclude timestamp from output and produce idential output every time.
