Summary	0000428: Cannot debug ext\openwrt\scripts\functions\tr181\wifi functions
Description	I am trying to debug wifi_radio_get_FrequencyBands function in wifi script. I add the "sh -x" and "sh +x" in the function like this: wifi_radio_get_FrequencyBands() { sh -x local phy="phy${1#radio}" local freq=`iw phy $phy info \| grep "MHz.dBm" \| head -1 \| awk '{print $2}'` sh +x [ "${freq#24}" = "$freq" ] && echo "5GHz" \|\| echo "2.4GHz" } But I can't get any output by this command "easycwmp get Device.WiFi.Radio.1.OperatingFrequencyBand" root@LEDE:/usr/share/easycwmp/functions# easycwmp get Device.WiFi.Radio.1.OperatingFrequencyBand If I remove the "sh -x" and "sh +x" from the function, I can get below output. root@LEDE:/usr/share/easycwmp/functions# easycwmp get Device.WiFi.Radio.1.Operat ingFrequencyBand { "parameter": "Device.WiFi.Radio.1.OperatingFrequencyBand", "value": "5GHz" } root@LEDE:/usr/share/easycwmp/functions# Would you help to guide me how to debug shell script functions? Thanks. Jackson
