RHEL5.X 重啓網卡出現./network-functions: line 78: .: ifcfg-eth0: file not found

錯誤信息：

因爲更新了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.

解決方法：
在78行中，修改 . $CONFIG 爲 . ./$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.

看了代碼後，發現要解決該問題，只須要作以下操做：
打開文件vi /etc/sysconfig/network-scripts/network-functions，改變以下行
第69行:
將 PARENTCONFIG='echo $CONFIG | sed 's/-[^-]*$//g'
改成 PARENTCONFIG="/etc/sysconfig/network-scripts/"

第70行：
將 PARENTDEVNAME=${PARENTCONFIG##/ifcfg-}
改成 PARENTDEVNAME=${PARENTCONFIG##/}

第78行：
將 . $CONFIG改成
. ./$CONFIG

再次重啓網絡，沒有發現以下報錯了
