Hello,
this is a forwarded feature request from http://bugs.debian.org/670615

Hello,
It would be really great to have a post-download command hook which would be
executed after each file is downloaded successfully by wget.
Currently, when running from scripts it is not easy to do something with
actually downloaded file if it is downloaded using recursion or if file is
generated dynamically, or filename is unknown or redirection took place.
for example
wget --post-download=md5sum http://ftp.gnu.org/gnu/bash/bash-4.2.tar.gz
md5sum will be then executed by wget, for example using system() command:
system("wget bash-4.2.tar.gz")
preferably with some additional environment variables set, like time of
download, wheter it was first download or already downloaded file previously
(but was running with -c flag), what was size, speed, original url, url after
last redirection, wheter redirection took place, what was dns and IP address
used and protocol (http/ftp, ipv4/ipv6, etc), average speed, number of
retries,
wheter html links was already changed to local or absolute ones from relative
ones, received cookies/headers, etc.
Actual system command will depend also on -O flag, -c, and whatever we are
using -nc, -nd, -x, nH, --cut-dirs, (and so also -r) and -P.
This command will be very useful in recursive processing as well when using
glob patterns, as well in case of redirects.
Instead of system() command, one can use fork/execve, which will not clobber
environment variables, as well make files with spaces (both downloaded one as
well used script) not a danger.
Thanks,
Witek
