[Compass-ci] Re: [PATCH compass-ci] sbin/es-repo-mapping.sh: create script that generates "repo" mapping

• if [ -x "$(command -v apk)" ]
• then

=> 'if ...; then' 是不是会好看些?

•    apk add install -y curl
  

• elif [ -x "$(command -v yum)" ]
• then

•    yum install -y curl
  

• elif [ -x "$(command -v apt-get)" ]
• then

•    apt-get install -y curl
  

• fi

+else

• echo "curl has install."

+fi
