Bash脚本和正则表达式问题

Question

Let's imagine that on my server, i have the following files : 让我们想象一下，在我的服务器上，我有以下文件：

foo@bar:/var/log/foo$ ls
fooFile1 fooFile2 logFile logFile.1 logFile.2

I wanted to create an archive containing every file but logFile.*. 我想创建一个包含每个文件的存档，但是logFile。*。 So I came up with the command : 所以我想出了命令：

foo@bar:~$ tar -czf foo.tar.gz /var/log/foo/!(logFile.*)

And it works fine ! 它工作正常！ However, when trying to create a script which does the same job : 但是，在尝试创建执行相同工作的脚本时：

#!/bin/bash

tar -czf foo.tar.gz /var/log/foo/!(logFile.*)

I came across the following error : 我遇到了以下错误：

./test.sh: line 3: syntax error near unexpected token '('
./test.sh: line 3: 'tar -czf foo.tar.gz /var/log/foo/!(logFile.*)'

The problem is not tar related (I met the same issue using ls instead of tar ) 这个问题与tar没有关系（我使用ls而不是tar遇到了同样的问题）

I don't understand where this error is coming from. 我不明白这个错误来自哪里。 Could anyone tell me where i am wrong ? 谁能告诉我哪里错了？

Place this line just below shebang: 将这条线放在shebang下面：

shopt -s extglob

to enable extended glob option in your script. 在脚本中启用扩展的glob选项。

!(logFile.*) is extended glob pattern that requires enabling extglob !(logFile.*)是扩展的glob模式，需要启用extglob
