ssh-keygen -T -j

[Earl A. Killian]

I was 8 hours into a ssh-keygen -T when the power went out. So I tried 
to restart by appending -j LINENO to the command line, but ssh-keygen 
just gave me the Usage message in response (and yes the usage for -T 
includes "[-j start_line]". The LINENO that I gave it was from the last 
output line before the crash where it says "processed LINENO of NUMLINES".

Is there any documentation on how this is supposed to work? The man page 
does not give me any additional information.
