FILE2DGR(1) DGR executables FILE2DGR(1)
NAME
file2dgr - DGR transmission test program
SYNOPSIS
file2dgr remoteHostName fileName [nbrOfCycles]
DESCRIPTION
file2dgr uses DGR to send nbrOfCycles copies of the text of the file named fileName to the dgr2file process running on the computer
identified by remoteHostName. If not specified (or if less than 1), nbrOfCycles defaults to 1. After sending all lines of the file,
file2dgr sends a datagram containing an EOF string (the ASCII text "*** End of the file ***") before reopening the file and starting
transmission of the next copy.
When all copies of the file have been sent, file2dgr prints a performance report:
Bytes sent = I<byteCount>, usec elapsed = I<elapsedTime>.
Sending I<dataRate> bits per second.
EXIT STATUS
0 file2dgr has terminated.
FILES
No configuration files are needed.
ENVIRONMENT
No environment variables apply.
DIAGNOSTICS
Diagnostic messages produced by file2dgr are written to the ION log file ion.log.
