在dockerfile中插入条件RUN语句

I am trying to write a docker file which will run a RUN command to search for a word in a package.json file and act upon it:

我正在尝试编写一个docker文件，它将运行一个RUN命令来搜索package.json文件中的一个单词并对其进行操作：

this is my simple dockerfile:

这是我简单的dockerfile：

FROM ubuntu:14.04

COPY package.json package.json

RUN if grep -q "grunt" package.json; then echo succeed fi

as you can see i just want a simple if statement but it get this error:

正如你所看到的，我只想要一个简单的if语句，但它会出现这个错误：

Step 2 : RUN if grep -q "grunt" package.json; then echo succeed fi
 ---> Running in af460df45239
/bin/sh: 1: Syntax error: end of file unexpected (expecting "fi")
INFO[0001] The command [/bin/sh -c if grep -q "grunt" package.json; then echo succeed fi] returned a non-zero code: 2

How should i run my command? thanks.

我应该如何运行我的命令？谢谢。

Just like when typing at the shell, you need either a newline or a semicolon before fi:

就像在shell中输入一样，在fi之前需要换行符或分号：

RUN if grep -q "grunt" package.json; then echo succeed; fi
                                             add this ^
