Fedora repository mirroring script using reposync

I'm back~ :D

As my first post of this holidays .. I give y'all the script i've been using to mirror and sync the fedora repos. The script is using reposync,repomanage (both provided by yum-utils) and createrepo , so you will need to yum for those them first.

#!/bin/bash -x

unset http_proxy
#export http_proxy=http://127.0.0.1:3128

# mirror root - the place you want the rpms to be downloaded
MROOT="/mnt/mirror/repos"

# processor architectures (space separated)
ARCHS="i686 x86_64"

# repository names (space separated)
REPOS="fedora updates"

if [ "$1" != "" ];then
    REPOS="$@"
fi

downcomps(){
        wget -N $1/repodata/comps.xml
}

# this part will download the comps.xml files .. it still need some improvements though
getcomps(){
        case "$1" in
        fedora)
                downcomps http://download.fedora.redhat.com/pub/fedora/linux/releases/7/Everything/i386/os/
        ;;
        updates)
                downcomps http://download.fedora.redhat.com/pub/fedora/linux/updates/7/i386/
        ;;
        *)
                echo error
        ;;
        esac
}

downrepo () {
    cd $MROOT
    if [ "$2" == "i686" ];then
       cd i386
    else
       cd $2
    fi
    echo "Sychronizing Repositories"
    reposync -r $1 -a $2 --newest-only -t /var/tmp/reposync-cache  
    STAT=$?
    if [ "$STAT" == "0" ];then
        cd $1
        echo "Cleaning old packages"
        repomanage --withbroken --old . |grep -v 'kernel\-' |grep -v -i 'nvidia'|grep -v -i 'fglrx'|xargs rm -rf
        rm -rf .repodata .olddata
        echo "Recreating repodata"
        getcomps $1
#        rm -f comps.xml
        if [ -e comps.xml ];then
            createrepo --groupfile comps.xml .
        else
            createrepo .
        fi
    fi
    cd $MROOT
}


#yum clean all --noplugins 
while [ "1" == "1" ];do
        for REPO in $REPOS;do
          # yum makecache --disablerepo=* --enablerepo=$REPO
           for ARCH in $ARCHS;do
              echo downloading $REPO $ARCH
              downrepo $REPO $ARCH
           done
        done
echo Update done, halting for 2 hours
sleep 7200
done
