# creating script file
starti(){

# move the script to SOURCE
mydir=$(echo $myarg | awk -F'.' '{print $1}') 
mkdir $mydir-0.0.1

mv ./$mydir.spec ~/rpmbuild/SPECS

cd ~/rpmbuild/SPECS

   sed '2d','4d','7,8d','20,22d','25,27d','31d' $mydir.spec

   # checking the spec file on error 
   check=$(rpmlint ~/rpmbuild/SPECS/$mydir.spec | awk '/checked/ {print $7}')
   if [ "$check" = "0" ];then
     echo "you did a good work lad!"
   else
     echo $check
     echo "problem with your SPECS file fix it F.I.A.T !!! (Fix it again $USER)"
fi

rpmbuild -bs ~/rpmbuild/SPECS/$mydir.spec
}

this is where it fails: ./rpmrevised.sh: line 41: starti: command not found i'm really tring to figure this out , but with no luck
