問題

glibcのバージョンを確認したいです。

答え

以下のいずれかで。

yumコマンドで

# yum list installed | grep glibc
glibc.x86_64                          2.12-1.166.el6_7.7        @updates
glibc-common.x86_64                   2.12-1.166.el6_7.7        @updates
glibc-devel.x86_64                    2.12-1.166.el6_7.7        @updates
glibc-headers.x86_64                  2.12-1.166.el6_7.7        @updates

rpmコマンドで
