RPM .spec with bash must changed but not know what wrong - rpmbuild

Question

Pls answer me and hope my question not so stupid but i first time put inside rpm bash skrip. May someone can sent link or tip what i must coorrect in my .spec
This rpm pakage must make just two thing - copy in linux folder /bin/ one file(inet.dbg) and next when cp make must start bash skrip for check library for this file.
This my bash skript
#!/bin/bash
ldd inet.dbg > t.t
ERR=`grep -i "not" t.t | wc -l`
if [[ $ERR -gt 0 ]]; then
grep -i "not" t.t > erg.e
echo "Die folgenden Bibliotheken wurden nicht gefunden:"
cat erg.e
rm t.t erg.e
else
ls -a ss.tar &> t.t
if [[ $? -eq 0 ]]; then
echo alles ok
else
echo no
fi
fi '
