1、
1.1 打开 /barrier_breaker/package/base-files/files/etc/init.d
加入 disable_sta_mode_wifi_interfaces
#!/bin/sh /etc/rc.common START=19 # just before network start disable_sta_mode_wifi_interface() { local section="$1" config_get mode $section 'mode' config_get ssid $section 'ssid' config_get disabled $section 'disabled' #获取的是uci中的内容，如果uci中没有才获取配置文件 if [ sta == $mode ] ; then if [ 0 -eq $disabled ] || [ -z $disabled ] ; then #判断disabled是否为0或为空 logger -s -t fqrouter disable sta mode wifi interface $ssid uci_set wireless $section disabled 1 else subvar="no_need_sta" echo "$subvar" > /tmp/temp.txt #不加目录不知存在什么地方 logger -s -t fqrouter does not need to open sta mode exit fi fi } start() { config_load 'wireless' config_foreach disable_sta_mode_wifi_interface 'wifi-iface' uci_commit logger -s -t fqrouter all sta mode wifi interfaces disabled }
注意：（1）、其中包含两个条件的判断语句要这样写
if [ 0 -eq $disabled ] || [ -z $disabled ] ; then
或
if [[ 0 -eq $disabled || -z $disabled ]] ; then
注意中括号要和里面的内容要有空格隔开。
（2）、赋值语句要这样写
subvar="no_need_sta"
等号两边不能有空格
