I'm using a CentOS 5.6 system. Since there is a bug in my version of grep. I want to upgrade to a new version. I tried to use yum to update(upgrade) it, but failed.
[root@localhost ~]# cat /etc/redhat-
redhat-lsb/ redhat-release
[root@localhost ~]# cat /etc/redhat-release
CentOS release 5.6 (Final)
[root@localhost ~]# grep --version
grep (GNU grep) 2.5.1
