Question

我有一个bash脚本如下：

#!/bin/bash
sh ~/Softwares/apache/kafka/kafka_2.11-0.10.0.0/bin/kafka-run-class.sh kafka.admin.ConsumerGroupCommand --describe --group $1 --zookeeper $2

我在终端上将此脚本称为如下：

kafka-describe my-kafka-consumer localhost:2181

我现在想传递一个变量而不是zookeeper地址，这样我就不必一直记住zookeeper的地址。例如，我希望能够调用kafka-describe命令，如下所示：

kafka-describe my-kafka-consumer integration - would run against the integration environment

kafka-describe my-kafka-consumer uat - would run against the uat environment

然后我可以在我的脚本中为不同的环境硬编码zookeeper地址的位置。我是编写bash脚本的新手。有关如何做到这一点的任何建议吗？

Answer 1

简单变量怎么样？

<强> variables.sh

#!/usr/bin/bash

INTEGRATION="localhost:2080"
UAT="localhost:8080"

<强> script.sh

#!/usr/bin/bash

# Imports variables from variables.sh file
source variables.sh

# "$VARIABLE" will give the value of the variable named VARIABLE
kafka-describe my-kafka-consumer "$UAT"

根据我的理解，我想下面的脚本将完成你的工作：

#!/bin/bash
kafka_group=$1 #store the group in a variable 
kafka_env=$2 #store the env in another variable

if [ "$kafka_env" = "integration" ]; then
   addr="localhost:2080" #change to whatever value you require for integration
elif [ "$kafka_env" = "uat" ]; then
   addr="localhost:8080" #change to whatever value you require for uat
else
   echo "invalid input"
   exit 1
fi

sh ~/Softwares/apache/kafka/kafka_2.11-0.10.0.0/bin/kafka-run-class.sh kafka.admin.ConsumerGroupCommand --describe --group ${kafka_group} --zookeeper ${addr}

Bash脚本中的模式匹配
