![apt-get 配置文件中使用什么语言?](https://linux22.com/image/887358/apt-get%20%E9%85%8D%E7%BD%AE%E6%96%87%E4%BB%B6%E4%B8%AD%E4%BD%BF%E7%94%A8%E4%BB%80%E4%B9%88%E8%AF%AD%E8%A8%80%EF%BC%9F.png)
例如,/etc/apt/apt.conf.d/50unattended-upgrades
我们有这样的内容:
// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
"${distro_id}:${distro_codename}-security";
// "${distro_id}:${distro_codename}-updates";
// "${distro_id}:${distro_codename}-proposed";
// "${distro_id}:${distro_codename}-backports";
};
// List of packages to not update (regexp are supported)
Unattended-Upgrade::Package-Blacklist {
// "vim";
// "libc6";
// "libc6-dev";
// "libc6-i686";
};
这里使用什么语言?
