Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

you really have the file /proc/net/wireless?


test -e /proc/net/wireless || echo "not found"

Comment by ncaio 303 weeks and 4 days ago

Yes I do, I ran your command, returned nothing.


cat /proc/net/wireless shows the data.
