我收到错误“array.sh:3:array.sh:语法错误:"(“意外") [英] I am getting error "array.sh: 3: array.sh: Syntax error: "(" unexpected"

问题描述

我编写了以下代码:

#!/bin/bash
#Simple array
array=(1 2 3 4 5)

echo ${array[*]}

我收到错误消息:array.sh: 3: array.sh: 语法错误:("意外

And I am getting error: array.sh: 3: array.sh: Syntax error: "(" unexpected

据我从 Google 了解到的情况，这可能是因为 Ubuntu 现在默认情况下不采用#!/bin/bash"...但我再次添加了该行，但错误是还在.

From what I came to know from Google, that this might be due to the fact that Ubuntu is now not taking "#!/bin/bash" by default... but then again I added the line but the error is still coming.

我也尝试过执行 bash array.sh 但没有成功！它打印空白.

Also I have tried by executing bash array.sh but no luck! It prints blank.

我的 Ubuntu 版本是:Ubuntu 14.04

My Ubuntu version is: Ubuntu 14.04

推荐答案

鉴于该脚本:

#!/bin/bash
#Simple array
array=(1 2 3 4 5)

echo ${array[*]}

并假设:

• 它位于您当前目录中名为 array.sh 的文件中；
• 你已经完成了chmod +x array.sh;
• 您在 /bin/bash 中安装了足够新的 bash 版本(您报告说您有 4.3.8，这当然足够新)；和
• 你正确地执行它

• It's in a file in your current directory named array.sh;
• You've done chmod +x array.sh;
• You have a sufficiently new version of bash installed in /bin/bash (you report that you have 4.3.8, which is certainly new enough); and
• You execute it correctly

那么应该可以正常工作.

then that should work without any problem.

如果您通过键入执行脚本

If you execute the script by typing

./array.sh

系统会注意#!/bin/bash这一行，使用/bin/bash执行脚本.

the system will pay attention to the #!/bin/bash line and execute the script using /bin/bash.

如果您通过键入以下内容来执行它:

If you execute it by typing something like:

sh ./array.sh

然后它将使用 /bin/sh 执行它.在 Ubuntu 上，/bin/sh 通常是到 /bin/dash 的符号链接，这是一个类似 Bourne 的 shell，不支持数组.这将准确地为您提供您报告的错误消息.

then it will execute it using /bin/sh. On Ubuntu, /bin/sh is typically a symbolic link to /bin/dash, a Bourne-like shell that doesn't support arrays. That will give you exactly the error message that you report.

用于执行脚本的 shell 不受您当前使用的 shell 或在 /etc/passwd 或等效项中配置为登录 shell 的 shell 的影响(除非您使用source 或 . 命令).

The shell used to execute a script is not affected by which shell you're currently using or by which shell is configured as your login shell in /etc/passwd or equivalent (unless you use the source or . command).

在您自己的回答中，您说您通过使用 chsh 将默认登录 shell 更改为 /bin/bash 解决了问题.这本身不应该有任何影响.(无论如何，/bin/bash 是 Ubuntu 上的默认登录 shell；您之前是否将其更改为其他内容?)

In your own answer, you say you fixed the problem by using chsh to change your default login shell to /bin/bash. That by itself should not have any effect. (And /bin/bash is the default login shell on Ubuntu anyway; had you changed it to something else previously?)

一定发生的事情是您在没有意识到的情况下将您使用的命令从 sh ./array.sh 更改为 ./array.sh.

What must have happened is that you changed the command you use from sh ./array.sh to ./array.sh without realizing it.

尝试运行 sh ./array.sh 并查看是否出现相同的错误.

Try running sh ./array.sh and see if you get the same error.
