DOS commands yield unexpected results

Certain DOS commands may behave unexpectedly, for the following reasons:

• Networked drives where the user does not have write permission in the root directory do not support DOS pipes--commands that include the "|" character. This occurs because a DOS pipe tries to create a temporary file in the root of the current drive.

• Some DOS applications, such as edlin, delete a file and then rewrite it to modify it. If the file links to another UNIX file, the link disappears, and a new, independent file takes its place.

• Some DOS commands report errors that do not seem to relate to their causes. For example, the DOS type command returns Invalid path or filename: when it receives the Access denied message from the server. This can happen when DOS tries to type an inaccessible file. Verify that the device, path, and file names have validity on the server and that the user has access privileges to them.
