I used something like this:
#%_use_internal_dependency_generator 0
#%__find_requires /home/sgrubb/bin/find-requires
and then ran a shell script that had this piece in it where $1 was a file
suspected of being a bash script by running the file command. Since people have
a habit of using a script name and not its full path, it uses which to resolve
the full path. This might be better done using the full rpm database that yum
operates off of. Anyways...this was the core of it:
# Then check its requirements
cmds=`/bin/bash --rpm-requires "$1" | sort | uniq | tr '()' ' ' | awk '{ print
$2 }'`
for c in $cmds
do
tgt=`which $c 2>/dev/null`
if [ x"$tgt" = x ] ; then
echo "$c cannot be resolved" 1>&2
continue
fi
tmp_r="`rpm -qf $tgt`"
if [ $? -eq 0 -a $RPM -eq 1 ] ; then
# Only use good results for rpms
r="$r\n$tmp_r"
else
r="$r\n$tgt"
fi
done
echo -e $r | sort | uniq
exit 0
