Purpose
The ERRORS command redirects diagnostic messages to a file that you specify or to the default file STDERR. If nothing is specified, the name of the files where errors are directed displays.
Syntax
ERRORS [ { TO | INTO | OVER } { file | STDERR | ME } ]
- TO
- That Ferret is to write diagnostic messages to a new file or to STDERR.
- INTO
- That Ferret is to append diagnostic messages to a specified file or to STDERR.
- OVER
- That Ferret is to overwrite an existing file or STDERR with current diagnostic messages.
- file
- The name of the destination file for diagnostic messages.
- STDERR
- The default file to which Ferret writes diagnostic messages.
- ME
- The synonym for STDERR.
Usage Notes
When you start Ferret, it writes diagnostic messages to STDERR by default.
You can use the ERRORS command to redirect the diagnostic messages in the following ways:
- To write to a new file only
- To append to an existing file
- To overwrite an existing file
- To display on your console
If you include the file parameter in the ERRORS command, the file you specify becomes the destination for diagnostic messages redirected from STDERR.
If you type the ERRORS command without any options, Ferret shows the name of the current diagnostic messages file STDERR on your system console.
