bash 脚本是否有某种“eof 处无换行符”规则？

我有两个文件，一个 env 文件和一个 run 文件。当我将它们部署到 Ubuntu 服务器时，出现错误：

./start-admin: 第 10 行: 语法错误: 文件意外结束

如果我部署然后在文件末尾添加换行符，它将显示错误。如果我删除它，错误就会消失。如果我再次部署并且不添加换行符，它仍然显示错误，但如果我添加换行符，错误就会消失。什么可能导致这种情况？

以下是我的脚本：

环境：

if [ "x${WD}" == "x" ];  then echo "missing required conf \"\${WD}\"" >&2; exit -1; fi

export JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64
export JAR_FILE="$WD/mfa-admin.jar"
export MYSQL_URL=url1
export MYSQL_USER=root
export MYSQL_PASSWORD=pwd
export DB_URL=url2
export DB_USER=user
export DB_PASSWORD=pwd2

export EMAIL_HOST=mail-inbox
export EMAIL_PORT=25
export EMAIL_PERMISSION=false
export FAKE_EMAIL=email
export ACTIVATION_URL=url

export BIND_HOST=0.0.0.0
export BIND_PORT=8282

开始：

WD=`dirname $0`;

JAVA_OPTS=""

if [ -r "$WD/admin.env.conf" ]; then
  . $WD/admin.env.conf
fi

当我收到此消息时，这是脚本中 、 、 或 字符串`不'匹配的结果。"有时，如果 if/then/fi、do/while 或 case/esac 语句不匹配，也会发生这种情况。我会仔细检查你的脚本。
