RHEL5.X 重启网卡出现./network-functions: line 78: .: ifcfg-eth0: file not found

错误信息：

由于更新了bash版本。
/etc/sysconfig/network-scripts/network-functions fails under bash 4.1.
The reason is that bash 4 fixed a bug in the source function (http://tiswww.case.edu/php/chet/bash/COMPAT) that cause the function to include the current directory in the path when sourcing files.

解决方法：
在78行中，修改 . $CONFIG 为 . ./$CONFIG
Line 78 in network-functions is ". $CONFIG" which means it wouldn‘t work if bash hadn‘t that bug.
It should be changed to ". ./$CONFIG" which solves the problem.

看了代码后，发现要解决该问题，只需要做如下操作：
打开文件vi /etc/sysconfig/network-scripts/network-functions，改变如下行
第69行:
将 PARENTCONFIG='echo $CONFIG | sed 's/-[^-]*$//g'
改为 PARENTCONFIG="/etc/sysconfig/network-scripts/"

第70行：
将 PARENTDEVNAME=${PARENTCONFIG##/ifcfg-}
改为 PARENTDEVNAME=${PARENTCONFIG##/}

第78行：
将 . $CONFIG改为
. ./$CONFIG

再次重启网络，没有发现如下报错了
