How to get wlan0 rate from cli

Question

question is in title, best would be from some file in /sys instead of parsing output of iwlist ?

I need this number from output of iwconfig "Bit Rate=54 Mb/s".

Thanks

after searching more about this, i found out that even iwconfig is calling syscall ioctl(d, SIOCGIWRATE, ...). So, parsing output of iwconfig or customizing source code of iwconfig would be optional.

I guess this would do it.

iwconfig wlan0 | grep Bit | awk '{print $2}' | sed 's/Rate=//'

This will return the data rate.

	yes, im doing with this iwconfig wlan0 \| grep Rate \| cut -f 2 -d "=" \| cut -f 1 -d " " now, but, still, it will be faster to read it from file ( if it is stored somewhere in decimal )then running iwconfig, grep,awk and sed ( or in my case 2x cut ) – Denwerko May 2 '11 at 16:52
	I don't think there is another way of getting the bit rate value. You can probably, without any problems run the command over 100 times per second if you want to. – Alex May 2 '11 at 21:47
