how i can check with pytty
what version of cgminer i have?>

/usr/bin/cgminer-api
Quite a bit of output from this, so you'll have to scroll back up the screen, but it's in there.
or u can do the below and see the version easier.
cgminer-api | grep cgminer
fyi no /usr/bin is needed since cgminer is in the executable path
root@antMiner:~# echo $PATH
/usr/bin:/usr/sbin:/bin:/sbin
Yes, that's quite a lot better - thanks m8.
