#!/bin/sh

# echo "^-v-^ JSON DB is running in development env!" && npm run db

# echo "^-v-^ JSON DB is running in development env!" && nodemon -w ./server.js localhost 8888

JSONDB="nodemon -w ./server.js localhost 8888"

${JSONDB} &
# chmod +x db.sh
# OR
# chmod 777 db.sh

# sudo ./db.sh
# nodemon -w ./server.js localhost 8888

# /bin/sh db.sh

# ps -ef | grep node
# sudo kill -9 <PID>

Linux Shell

编写首个Shell脚本

打开你使用的文本编辑器，粘贴如下内容：

#!/bin/bash
echo "Hello World!"

将其保存成 1st.sh 再执行看看效果：

chmod 755 1st.sh

./1st.sh

执行成功了，是不是非常简单。

下面我们再建立一个 2nd.sh 并粘入如下内容：

#!/bin/bash
echo "What is your name?"
read a;
echo "Hey $a! what is your Favorite Website?"
read b;
echo -e "That's Nice to know @$a that $b is your favorite Website"
