Ins and Outs of Inputs

I often browse through various Fedora packages and miss having git tags in package repositories corresponding with builds done in koji. Therefore I created following simple bash script that will create git tags in current git repo (if it's a Fedora package).

#!/bin/bash

giturl=`fedpkg giturl`
if [ $? -ne 0 ];then
    echo "This doesn't look like fedora package directory"
    exit 1
fi

pkgname=`echo "${giturl}" |\
         sed -e 's|git://pkgs.fedoraproject.org/\(.*\)?.*|\1|'`
# make sure we are up-to-date
git fetch

# go through last 3 releases (incl. rawhide)
for dist in f15 f16 f17;do
    builds=`koji list-tagged "${dist}" "${pkgname}" | \
        grep "${pkgname}" | awk '{print $1}'`
    for build in $builds;do
        # task urls sometimes have ".git" suffix
        git_sha=`koji buildinfo "${build}" | grep '^Task:' | \
            sed -e "s|.*${pkgname}\(\.git\)*:\(.*\))|\2|"`
        version=`echo $build | sed -e "s:${pkgname}-::"`
        echo BUILD: $pkgname\($version\) = $git_sha
        git tag "${version}" "${git_sha}"
    done
done

Enjoy!
