Redirecting Input and Output
When you first start Ferret, it accepts input from STDIN, the console input file,
and directs output to STDOUT, the console output file.
By using the Ferret INPUT and OUTPUT commands, you can redirect the Ferret input and
output data to files that you specify. Also, you can do the following:
Append Ferret data output to an existing output file
Overwrite an existing output file
Write only to a new file
Display the current output file
When you direct output to a file with the OUTPUT command, Ferret echoes all input
and diagnostic messages to that file. For more information, see “INPUT” on page 569 and “OUTPUT” on page 570.
