window logstash.bat -e 실행시 single quote error

Learning Elastic Stack 6.0 보는데..... 정말 저자를 패고 싶다.

테스트를 안한 건지.... 버전업이 되면서 바뀐건지....

logstash를 윈도우에 설치하고 테스트 해 보는 예제인데....

single quote(작은 따음표)를 주고 실행하면 아래와 같은 오류가 발생한다.

C:\logstash-6.6.0\bin>logstash.bat -e 'input { stdin { } } output { stdout { } }'

ERROR: Unknown command '{'

See: 'bin/logstash --help'

[ERROR] 2019-02-11 00:58:05.745 [main] Logstash - java.lang.IllegalStateException: Logstash stopped processing because of an error: (SystemExit) exit

double quote(큰 따음표)로 변경해서 실행하면 잘 되는거 같은데....

C:\logstash-6.6.0\bin>logstash.bat -e "input { stdin { } } output { stdout { } }"

Sending Logstash logs to C:/logstash-6.6.0/logs which is now configured via log4j2.properties
