Bash的语法错误：＆QUOT; [：找不到＆QUOT; [英] Bash syntax error: "[[: not found"

问题描述

我与当前工作的服务器（RHEL4）在bash脚本工作。我发展我的笔记本电脑与Ubuntu 10.04，但我不认为该平台是造成问题的原因。

下面是发生了什么：
我有一个调用另一个脚本，完成大部分工作的骨架脚本。然而，它使呼叫getConfig.sh了很多。 getConfig.sh基本上只是一些解析命令行参数（使用getopts的），并调用Java程序来解析一些XML文件。不管怎么说，getConfig.sh被扔了很多错误（但仍似乎工作）。

下面是我得到消息

  

getconfig.sh：89：[[：未找到

  getconfig.sh：89：[[：未找到

  getconfig.sh：94：[[：未找到

我得到每次运行时这三个错误;然而，脚本完成和Java code运行。

这里的relavent code部分

 parseOptions $ *如果[[$ {} debugMode==真]];然后
    DEBUG = -  DDEBUG =真
    回声$ {JAVA_HOME} /斌/ java的$ {} DEBUG = -Djava.endorsed.dirs $ {} JAXP_HOME $罐子（目录名称$ 0）/GetXPath.jar $ {XML_FILE} $ {} xpath_查询
网络

89号线parseOptions $ *和线94是网络连接

感谢您的答案。

解决方案

如果你的脚本是可执行的，你正在执行它像 ./ getconfig.sh ，第一行你的脚本需要是：

 ＃！/斌/庆典
 

如果没有家当行

，你的脚本将是 SH PTED间$ P $不明白 [在如果语句。

否则，你应该运行脚本，比如庆典getconfig.sh ，不可以 SH getconfig.sh 。即使你的默认shell是bash，脚本与 SH 将使用一组简化了bash的功能，以符合POSIX标准兼容的多运行。 [是被禁用的特色之一。

I'm working with a bash script that is currently working on a server (RHEL4). I'm developing on my laptop with Ubuntu 10.04, but I don't think the platform is causing the problem.

Here's what's happening: I have a skeleton script that calls another script that does most of the work. However, it makes calls to getConfig.sh a lot. getConfig.sh basically just parses some command line argument (using getopts) and calls a Java program to parse some XML files. Anyways, getConfig.sh is throwing up lots of errors (but still seems to work).

Here's the message that I'm getting

getconfig.sh: 89: [[: not found
getconfig.sh: 89: [[: not found
getconfig.sh: 94: [[: not found

I get those three errors every time it runs; however, the script completes and the Java code runs.

Here's the relavent code section

parseOptions $*

if [[ "${debugMode}" == "true" ]] ; then
    DEBUG="-DDEBUG=true"
    echo "${JAVA_HOME}/bin/java ${DEBUG} -Djava.endorsed.dirs=${JAXP_HOME} -jar $(dirname $0)/GetXPath.jar ${XML_File} ${XPath_Query}"
fi

Line 89 is "parseOptions $* and line 94 is "fi"

Thanks for the answers.

解决方案

If your script is executable and you are executing it like ./getconfig.sh, the first line of your script needs to be:

#!/bin/bash

Without that shebang line, your script will be interpreted by sh which doesn't understand [[ in if statements.

Otherwise, you should run your script like bash getconfig.sh, not sh getconfig.sh. Even if your default shell is bash, scripts run with sh will use a reduced set of bash's features, in order to be more compliant with the POSIX standard. [[ is one of the features that is disabled.
