TransCoder 1 (one) Commands in Linux

[uktony]

This is transcoder 1 (I know old technology, but lets not go there)

; sc_trans accepts the following signals:
; USR1 - reload playlist off disk (will not interrupt current playing stream)

But what is the syntax for issuing the commands?

./sc_trans_linux USR1
./sc_trans_linux/USR1
./sc-trans-linux -USR1

So while I am here, SIGUSR1 - Reload playlist, in transcoder2 is executed with what syntax?
