I don't think this is useful for anything but my own debugging.  This
program searches at about 80K nodes per sec on a P6/200, and nearly 200K
nodes per sec on a PII/450.  After 5 seconds you have 1,000,000 lines of
output, which is hopeless to scan.

I often use it by putting the right commands in a file, like this:

sd=4
tr 100
ponder=off
setboard <to some test position>
move
quit

then run crafty:

crafty <input_file >output_file

and when it finishes I can edit output_file and poke around in it...
