Also as a more direct answer to your question, if the binary is 
currently active (it shows up in ps aux) then

you could do

ps ax -o cmd | grep [t]racker

to find the command-line of the binary (the full path).

or

cat /proc/$(pgrep tracker | head -1)/cmdline; echo

for something more convoluted ;-).
