oh, sure, i understand that.  but you just ran three or four
processes to get a text string that was available in the first
place.  :-)  ("iwgetid -r" would work nicely too, if you have it.)

except that those examples both assume that the interface is
always configured via DHCP, correct?  that's often not the case --
if i need to configure a static IP on some networks, i need to
pass different information to ifup, or whatever.  and for that i
need the ssid.

anyway, now i understand the history of the feature.  i think
i would have added ssid as an argument, but the interface is
certainly sufficient as is.  thanks!
