1  centos(以centos 6.0為例)：

(1) 可通過rpm -qa | grep glibc檢視系統目前安裝了哪些和glibc有關的包：

[[email protected] ~]# rpm -qa | grep glibc

glibc-2.12-1.47.el6_2.12.i686

glibc-headers-2.12-1.47.el6_2.12.x86_64

glibc-common-2.12-1.47.el6_2.12.x86_64

glibc-devel-2.12-1.47.el6_2.12.x86_64

glibc-2.12-1.47.el6_2.12.x86_64

可以看到系統上glibc的版本號為2.12。

如果想進一步檢視，可通過rpm -qi glibc：

[[email protected] ~]# rpm -qi glibc

Summary : The GNU libc libraries

Description :

The glibc package contains standard libraries which are used by

multiple programs on the system. In order to save disk space and

memory, as well as to make upgrading easier, common system code is

kept in one place and shared between programs. This particular package

contains the most important sets of shared libraries: the standard C

library and the standard math library. Without these two libraries, a

Linux system will not function.

(2) 也可以通過檢視ls -l /lib/libc.so.6輸出結果：

[[email protected] ~]# ls -l /lib/libc.so.6

lrwxrwxrwx. 1 root root 12 5月 21 17:46 /lib/libc.so.6 -> libc-2.12.so

2  ubuntu(以ubuntu 11.04為例):

(1) 檢視 ls -l /lib/i386-linux-gnu/libc.so.6的輸出：

lrwxrwxrwx 1 root root 12 2012-07-15 09:14 /lib/i386-linux-gnu/libc.so.6 -> libc-2.13.so

(2) 也可以使用 apt-cache show libc6:
