If done correctly, we should not miss any of them.
Something like this (copied from find-requires) will find all perl
scripts from list of files given on stdin:
filelist=`sed "s/[]['\"*?{}]/\\\\\&/g"`
scriptlist=`echo "$filelist" | grep -v /usr/doc | grep -v /usr/share/doc | xargs -r file | \
egrep ":.* (commands|script)" | cut -d: -f1`
for f in $scriptlist; do
[ -r $f -a -x $f ] || continue
interp=`head -n 1 $f | grep '^#!' | sed -e 's/^\#\![ ]*//' | cut -d" " -f1`
interplist="$interplist $interp"
case $interp in
*/perl) perllist="$perllist $f" ;;
esac
done
So we can make a script that will extract an rpm in a temporary
directory with rpm2cpio, find perl scripts, and print source rpm if a
perl script is found. And after running this script on all packages we
have the list of what we need to rebuild.
I won't have time to do it now or this weekend, but will try to do it
on monday if nobody does it before.
