_rpm_check() {
  echo "$check_prerequisite_str"

  do
    printf "    %s %s"  "$rpm" "${line_str2:${#rpm}}"
    rpm -qa | grep "^$rpm-" > /dev/null
    if [ $? -eq 0 ]; then
      echo " [Success]"
    else
      echo " [Fail]    (Install [$rpm] package !)"
    fi
  done
  echo ""
}
 
line_str2='........................'
 
_rpm_check

결과를 한 번 볼까?
