you can send something to $0-xxx variables, but you should only do it if it makes sense.

I often create abstractions using $0 as an argument, such as [line-seg 1 2 $0], and then $3 in the abstraction is the same as $0 in the parent. if you really want, you can export the individual $0-values to a text file to be read in the command line. But is it necessary?

$0 is a unique number that only the abstraction itself knows about. Typically you use it to keep things local. Just like you can't send a message to [r $0_msg] from another patch, you can't do it with "-send", either.

Just create a new patch, put your abstraction there and add a [receive foo] (without $0!) that will send the appropriate message to the abstraction. Now you can do

$ pd -nogui -send "foo 1"

Hi,

I have a patch like

[r $0_msg]

|

[print]

And would like to run Pd from command line (-nogui -send "....") and send something to the receive object.

How can I pass the '$0_msg' name in a way bash and Pd understand it?

Have tried different combinations of quotes and bars, but nothing works... :/

thanks!
