Raspbian的FS中存储的raspi-config脚本在哪里？

尽管raspi-config脚本可以在首次启动时进行方便的设置，但我拥有Raspberry Pi的原因之一是帮助我了解计算机菜单后面的内容。

我想看一下raspi-config脚本，并了解它是如何工作的。我在网上找到了部分脚本，但是（显然）它仅包含仅编辑config.txt文件的部分，我想知道它还会影响什么以及如何影响。

我想查看raspi脚本的全文，但尚未在我的文件系统中找到。有人可以提供位置吗？

目前，我不想解释它是如何工作的。我想自己弄清楚。（尽管这可能是以后的问题。）

其他两个答案都是正确的，可以让您查看和研究文件的工作方式。但是，出于教您钓鱼而不是给您钓鱼的想法，如果执行以下操作，它将帮助您在系统上查找任何文件。

sudo find / -name 'raspi-config'

分解：

sudo告诉系统以root特权运行此命令-这样可以防止许多错误使常规用户（pi）无法访问的目录混乱。

查找 Linux命令的名称以查找文件和目录。

/告诉find命令搜索文件系统的根目录及其所有子目录。

-name告诉find命令按文件名搜索。

'raspi-config'这是您要搜索的文件名。

要查找其他文件，只需将raspi-config替换为您要查找的文件的名称。find命令还有许多其他选项，您可以通过键入以下内容找到大多数linux命令的所有详细信息

man find

在命令行上。

Man是手册的缩写，它打印紧随其后的Linux命令的手册页（帮助页）。

raspi-config文件的完整路径为/usr/bin/raspi-config：

pi@raspberrypi ~ $ which raspi-config
/usr/bin/raspi-config

尽管我无法确切告诉您raspi-config在文件系统上的何处，但其源代码托管在GitHub上。

这是由asb创建的工具，他在正式的Raspberry Pi论坛上也似乎是主持人。您可以在asb / raspi-config中找到源。

编辑：这是完整的代码，在这里也是从上面链接的git repo中提取的：

使用 sudo find / -name 'raspi-config!'不需要。它搜索整个文件系统，并在找到匹配项后继续执行。这是完全错误的工作工具。

只需使用which raspi-config。效率更高。
