后台执行shell脚本

    while read line
    do
        boardIP=`echo "${line}" | awk -F"baseip=" {'print $2'} | awk -F"\"" {'print $2'}`;
        echo "${boardIP}";
        #主控板同时有vcs节点和node节点，去掉vcs节点。
        nodeID=`echo "${line}" | awk -F"id=" {'print $2'} | awk -F"\"" {'print $2'} | awk -F"-" {'print $1'}`;
        if [ "-${boardIP}" != "-" ] && [ "_${nodeID}" != "_Vcs" ]
        then
						
	          SyncSingleBoard ${boardIP} $1 2>&1 &

        fi;
     done <${ClusterBoardsFile};	

2.  test.sh  > /dev/null 2>&1;

3.添加操作系统命令

Alias="alias mdxsync='/opt/command_mdxsync.sh $1'";
Root_Bashrc_File="/root/.bashrc";

Alias_Mdx_Sync=`grep 'alias mdxsync=' ${Root_Bashrc_File}`;
if [ "-${Alias_Mdx_Sync}" = "-" ]
then
    echo "${Sync_All_Board_Alias}" >> ${Root_Bashrc_File};
    source ${Root_Bashrc_File}
    echo "set the alias opasswd success";
fi
