[PD] shell pipe to signal]

[Alexandre Quessy]

This command adds ";" at the end of every line of a text file before to send 
it. Then, we would just need to create a fifo with something like tail -f in 
order to create a udp channel to pd. 

cat data.txt | while read line; do echo "${line};" | nc -ub -q 0  localhost 
3001; done
