我想通过“locale-gen”从文件“locale.gen”中提取每个第一个头

我正在使用 Docker 映像并正在构建一个 dockerfile。该文件locale.gen（来自）包含与语言一起的/etc/locale.gen注释：#

ca_ES.UTF-8 UTF-8 # Catalan (Spain)
de_DE.UTF-8 UTF-8 # German (Germany)
el_GR.UTF-8 UTF-8 # Greek (Greece)
en_GB.UTF-8 UTF-8 # English (United Kingdom)
en_NZ.UTF-8 UTF-8 # English (New Zealand)
en_US.UTF-8 UTF-8 # English (United States)
eo          UTF-8 # Esperanto

pt_BR.UTF-8 UTF-8 # Portuguese (Brazil)

uk_UA.UTF-8 UTF-8 # Ukranian (Ukraine)
xh_ZA.UTF-8 UTF-8 # Xhosa (South Africa)
zh_CN.UTF-8 UTF-8 # Chinese (China)

如果我运行简单的命令locale-gen，它会因为注释而失败，这就是为什么我必须使用该选项awk -F "#" '{print $1}'，但它仍然失败。

看看它在 dockerfile 中的样子：

我建议您考虑更改 Docker 文件以复制源文件，然后修改它：
