Gentoo Webapp Update Check

Folgendes Skript verwende ich gerade, um die Versionen der installierten Webapps unter Gentoo zo prüfen:

#!/bin/bash

echo "Non-latest webapps installed: "

echo
for i in `webapp-config --list-installs`

do

        verline=$((`/usr/bin/eix -el \`cat $i/.webapp | grep WEB_PN | awk -F'"' '{print $2}'\` | grep -n 'Homepage:' | awk -F':' '{print $1}'`-1))

        latever=`/usr/bin/eix -el \`cat $i/.webapp | grep WEB_PN | awk -F'"' '{print $2}'\` | head -n $verline | tail -n 1 | awk -F'(' '{print $1}' | sed 's/Installed versions://' | awk -F' ' '{print $1}'`

        webver=`cat $i/.webapp | egrep "^WEB_PVR" | awk -F'"' '{print $2}'`

        if [ "$webver" != "$latever" ]

        then

                echo "========== Web-App installed in $i =========="

                cat $i/.webapp | egrep "^WEB_PN|^WEB_PVR|^WEB_INSTALLEDDATE|^WEB_HOSTNAME|^WEB_INSTALLDIR"

                echo

                /usr/bin/eix -e `cat $i/.webapp | grep WEB_PN | awk -F'"' '{print $2}'`

                host=`echo $i | awk -F'/' '{print $5 "." $4}'`

                vdir=`echo $i | awk -F'/' '{print "/" $2 "/" $3 "/" $4 "/" $5 "/"}'`

                instdir=`echo $i | awk -F'/' '{print $7}'`

                app=`cat $i/.webapp | grep WEB_PN | awk -F'"' '{print $2}'`

                sflag=

                if [ "`echo $i | awk -F'/' '{print $6}'`" == "htdocs-secure" ]

                then

                  sflag="--secure"

                fi

                echo "please check following line and update with: "

                echo "webapp-config -U -h $host -D vhost_root=\"$vdir\" -d $instdir $app $latever $sflag"

                echo

                echo "================================================================================"

                echo

        fi

done
