Hi,
Below is the actual code that I am using FWIW, I don't claim it is
perfect, but it does the job of collecting the WinSCP files of a
release, as well as compiling checksum files from the release's readme file.
The format of the readme file has been constant for quite some time (if
not since it was first devised). The files I want haven't changed either.
Of course it would be easier if they released proper md5sum, sha1sum and
sha256sum files so that I didn't need to construct them.
The download version is within the file name of the shell script. I
could just as easily use the directory name to determine the version
though. Basically I create a directory, copy in or hard link the file
from "last time", adjust it if necessary (name at least) and run it.
The script seems to be quite effective in getting all the files and
confirming they are valid according to the checksums provided in the readme.
I actually haven't used WinSCP itself for a while now as I only use
Windows for very few things these days (aside from when I am working on
other people's machines providing IT support services).
Cheers
A.
