Linux的：非法读取选项-a [英] Linux: Illegal option read -a

问题描述

我已经找到了这个问题的答案......只是想为别人提供一些信息，谁也遇到了这个问题...

I have found the answer for this question... Just want to provide some information for others, who met this problem too...

在我的系统，我得到了这个问题，因为我使用了 SH main.sh 来处理我的shell脚本，而忽略打击和壳牌之间的区别。

In my system, I got this problem because of I used the sh main.sh to process my shell script and ignore the difference between "Bash" and "Shell".

为了解决这个问题，你可以尝试改变模式转换成可执行的，通过使用使用chmod + X ，并使用 ./ 执行程序。

In order to solve this problem, you might try to change the mode into executable, by using chmod +x and using ./ to execute the program.

祝你好运！

推荐答案

错误：

Illegal option read -a

结果显示，因为你想在shell中运行它，其中的读 ISN的 -a 选项 T定义。

was shown because you were trying to run it in a shell where the -a option for read isn't defined.

命令搭配chmod + X script.sh 无关，用它做。它只是仅仅给出脚本执行权限。

the command chmod +x script.sh has nothing to do with it. It just merely gives the script execution permission.

您正试图通过在命令来运行的Bourne shell命令sh script.sh 和Bourne shell的读不具有阅读 -a 选项。这是一个Bash的功能。

You were trying to run the command in Bourne shell by the command sh script.sh and Bourne shell read doesn't have the -a option for read. It's a Bash feature.

与运行./ 不太答案。你可以说，至少有：以 path_to_the_script 运行它，因为不是每一次你的脚本会在当前目录中结束

Running with ./ is not quite an answer. You could say at least : run it with path_to_the_script because not every time your script will end up in the current directory.

您可以用庆典main.sh 运行它，而不是 SH main.sh 。

You can run it with bash main.sh instead of sh main.sh.
