从右向左重击连锁字符串

我正在调试这个catalina.sh脚本,现在:

echo "$CATALINA_HOME"
  echo "dot " .
  echo "179"
  if [ -r "$CATALINA_HOME"/bin/setclasspath.sh ]; then
    echo "qui 81"

    . "$CATALINA_HOME"/bin/setclasspath.sh
  else
    echo "185"
    echo "Cannot find $CATALINA_HOME/bin/setclasspath.sh"
    echo "This file is needed to run this program"
    exit 1
  fi

输出为:

 /home/sysadm/2_KNOWAGE/Knowage_6-2_ARES/Knowage-Server-CE 
 dot  . 
 179
 185
 /bin/setclasspath.shsadm/2_KNOWAGE/Knowage_6-2_ARES/Knowage-Server-CE
 This file is needed to run this program

当setclasspath.sh实际存在时,它具有写权限并且应该在那里。所以我希望它能被找到并运行。
