[Asterisk-Users] asterisk -rx 'sip show peers'

[Ronald Wiplinger]

I upgraded recently to Asterisk SVN-branch-1.2-r25165M

the commandline  
   asterisk -rx 'sip show peers'

returns with the first line:
on

Is that a bug, or how can I omit it?

I used:
asterisk -rx 'sip show peers'|grep OK|sort | tee /dev/tty |wc -l; echo " 
registered at ELMIT"

which results (because of on) to:

Binary file (standard input) matches
1
