You can use the threshold gate for this:
ecasound -i huge-sample.wav -o trimmed-sample.wav -ge:1,1,0
Depending on the type of silence (total, noise, ..), you may need
to play with the -ge params (see man ecasound(1)).
PS And remember to set the correct sample format with "-f"
if you don't want to change the audio format parameters.
