Bash 스크립트에 "eof에 개행 금지" 규칙이 있나요?

env 파일과 실행 파일이라는 두 개의 파일이 있습니다. Ubuntu 서버에 배포하면 오류가 발생합니다.

./start-admin: 10행: 구문 오류: 예기치 않은 파일 끝

배포한 다음 파일 끝에 개행을 추가하면 오류가 표시됩니다. 제거하면 오류가 사라집니다. 다시 배포하고 줄바꿈을 추가하지 않으면 여전히 오류가 표시되지만 줄바꿈을 추가하면 오류가 사라집니다. 이 문제의 원인은 무엇입니까?

아래는 내 스크립트입니다.

환경:

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 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
