nexutil command option list

[pengchengNJ]

I'm wondering how to find a comprehensive list of nexutil command. I think the nexutil is a powerful tool to communicate with chip firmware, but it's only a blackbox without clear and comprehensive documentation. If you have summarized the option list, could you share it? Thanks.

nexutil --help?

I second @davidrozen76's answer.... nexutil --help is the command to use... If you can't do that for whatever reason, here is the commands from the nexutil.c file:

{"interface-name", 'I', "CHAR", 0, "Set interface name (default: wlan0)"},
{"monitor", 'm', "INT", OPTION_ARG_OPTIONAL, "Set/Get monitor mode"},
{"promisc", 'p', "INT", OPTION_ARG_OPTIONAL, "Set/Get promiscuous mode"},
{"scansuppress", 'c', "INT", OPTION_ARG_OPTIONAL, "Set/Get scan suppress setting to avoid scanning"},
{"disassociate", 'd', 0, 0, "Disassociate from access point"},
{"get-custom-cmd", 'g', "INT", 0, "Get custom command, e.g. 107 for WLC_GET_VAR"},
{"set-custom-cmd", 's', "INT", 0, "Set custom command, e.g. 108 for WLC_SET_VAR"},
{"custom-cmd-buf-len", 'l', "INT", 0, "Custom command buffer length (default: 4)"},
{"custom-cmd-value", 'v', "CHAR/INT", 0, "Initialization value for the buffer used by custom command"},
{"custom-cmd-value-int", 'i', 0, 0, "Define that custom-cmd-value should be interpreted as integer"},
{"custom-cmd-value-base64", 'b', 0, 0, "Define that custom-cmd-value should be interpreted as base64 string"},
{"base64-output", 'R', 0, 0, "Write base64 encoded strings to stdout instead of hex dumping"},
{"raw-output", 'r', 0, 0, "Write raw output to stdout instead of hex dumping"},
{"dump-wl_cnt", 'w', 0, 0, "Dump WL counters"},
{"dump-objmem", 'o', "INT", 0, "Dumps objmem at addr INT"},
{"chanspec", 'k', "CHAR/INT", OPTION_ARG_OPTIONAL, "Set chanspec either as integer (e.g., 0x1001, set -i) or as string (e.g., 64/80)."},
{"security-cookie", 'x', "INT", OPTION_ARG_OPTIONAL, "Set/Get security cookie"},
{"use-udp-tunneling", 'X', "INT", 0, "Use UDP tunneling with security cookie INT"},
{"broadcast-ip", 'B', "CHAR", 0, "Broadcast IP to use for UDP tunneling (default: 192.168.222.255)"},
{"revinfo", 'V', 0, 0, "Dump revision information of the Wi-Fi chip"},

I have stumbled on this issue looking for description of command codes used with g and s parameters. If anyone next come here in search of it, they are located in nexmon\patches\include\nexioctls.h file. Here is an excerpt :
