But you and Ville, both indictated that you're using the URL above and
post-processing it to get the names.

So can't you just combine the 2 things to do:

---
#!/bin/bash

full_clone=0
base_url='http://pkgs.fedoraproject.org'

set -ex

[ -e pkgdb_list ] || {
   wget \
    -c https://admin.fedoraproject.org/pkgdb/lists/bugzilla\?tg_format\=plain \
    -O pkgdb_list
}

pkgs=$( awk -F\| '/\}/ {print $2}' pkgdb_list )
for pkg in $pkgs ; do
	echo "Grabbing the specfile for $pkg"
	(
	cd ~/fedora-specs
	[ -e $pkg.spec  ] || {
		wget -o ~/tmp/$pkg.log -O $pkg.spec \
			"$base_url/cgit/${pkg}.git/plain/${pkg}.spec?id=HEAD"
	}
	)

	[ $full_clone == 0 ] && continue

	echo "Grabbing the git repo for $pkg"
	(
	cd ~/fedora-git
	[ -d $pkg  ] || {
		git clone git://pkgs.fedoraproject.org/git/${pkg}.git >&1
	) > ~/tmp/${pkg}-git.log &
done
---
and then wait a long time ;P

As an aside, Any guesses as to how big the ~/fedora-git dir would be
after running the script above?

Yours Tony
