如何知道我正在使用哪个 Linux 发行版？
uname -a给出
Linux xxxxxx.net 2.6.9-42.0.3.EL.wh1smp #1 SMP Fri Aug 14 15:48:17 MDT 2009 i686 i686 i386 GNU/Linux
我怎么知道这是 Ubuntu/Debian/Fedora 还是 Redhat？
我用它/etc/init.d/serviced restart来重启服务，似乎不是 Redhat 系列的
[itf][~]$ cat /etc/issue
cat: /etc/issue: No such file or directory
[itf][~]$ cat /etc/issue.net
cat: /etc/issue.net: No such file or directory
[itf][~]$ lsb_release -a
-sh: lsb_release: command not found
[itf][~]$ cat /etc/*-release
cat: /etc/*-release: No such file or directory
[itf][~]$ cat /etc/*-version
cat: /etc/*-version: No such file or directory
[itf][~]$ cat /etc/*release
cat: /etc/*release: No such file or directory
[itf][~]$ cat /etc/*_release

尝试http://legroom.net/2010/05/05/generic-method-determine-linux-or-unix-distribution-name。
结合查询 LSB 实用程序、发行版信息文件和 uname 中的内核信息的技术组合。它将采用它能找到的最具体的发行版名称，必要时返回通用 Linux。它还将识别 UNIX 变体，例如 Solaris 或 AIX。
