stream - stream data between source and sink stream [ -a ] [ -b bufsize ] file1 [ file2 ] Stream creates a process that uses stream (see sys-read (2)) to stream data in chunks of at most bufsize bytes (default: .LR Sys->ATOMICIO , or 8192 bytes) from file1 to the standard output. If file2 is provided, the two files are instead cross-connected by two streaming processes: one process streams data from file1 to file2 , and the other streams data from file2 to file1 . In all cases, stream writes data to the destination file in full buffers of bufsize bytes.

Stream waits for all streaming processes to stop before returning, unless the -a (asynchronous) option is given, which causes it to return after spawning the streamers.
