.TH STREAM 1 .SH NAME stream \- stream data between source and sink .SH SYNOPSIS .B stream .RB [ \-a ] .RB [ \-b .IR bufsize ] .I file1 [ .I file2 ] .SH DESCRIPTION .I Stream creates a process that uses .I stream (see .IR sys-read (2)) to stream data in chunks of at most .I bufsize bytes (default: .LR Sys->ATOMICIO , or 8192 bytes) from .I file1 to the standard output. If .I file2 is provided, the two files are instead cross-connected by two streaming processes: one process streams data from .I file1 to .IR file2 , and the other streams data from .I file2 to .IR file1 . In all cases, .I stream writes data to the destination file in full buffers of .I bufsize bytes. .PP .I Stream waits for all streaming processes to stop before returning, unless the .B -a (asynchronous) option is given, which causes it to return after spawning the streamers. .SH SOURCE .B /appl/cmd/stream.b .SH SEE ALSO .IR cat (1), .IR sys-read (2)
