downloading sourcecs in an RPM specfile

22 Aug 2008
Here's a quick hack to download all sourcefiles from a specfile automatically.

#!/bin/bash

specfile=$1

OLDIFS=$IFS
IFS="
"

sedcmd="sed"

for varline in `cat "$specfile" |grep "^%define"`;
do
    var=`echo "$varline" | awk '{print $2}'`
    val=`echo "$varline" | awk '{print $3}'`

    sedscript="s:%{$var}:$val:g"
    sedcmd="$sedcmd -e $sedscript"
done

IFS=$OLDIFS

mkdir -p /usr/src/redhat/SOURCES
for url in `cat $specfile | $sedcmd | grep "^Source" | awk '{print $2}'`;
do
 f=`echo "$url" | sed 's:.*/::'`
 wget -O "/usr/src/redhat/SOURCES/$f" "$url"
done
