Gentlemen, I have made http://jidanni.org/comm/radio/programs/selcal :
generate ICAO SELCAL tones just like on HF aviation radio using xmms
on GNU/Linux. Purpose of this program: bring the sounds of air
traffic control into one's living room to impress guests, I suppose.


Ran fine over here except line 60 give me:
sh: line 1: pidof: command not found

60:die if system "pidof $prog /dev/null || { $prog& sleep 1;}";

Now how can I use this? =D
