NOTE Many administrators know that they can set environmental variables using the Environment
Variables dialog box. To access this dialog box in a GUI version of Windows, right-click My
Computer and choose Properties from the context menu. Select the Advanced tab of the System
Properties dialog box. Click Environment Variables to display the Environment Variables dialog
box. Unfortunately, Server Core lacks the interface elements required to use this option.
When you work at the command line, you often need environment variables in addition to those
Windows uses. For example, the COPYCMD environment variable affects the Copy, Move, and XCopy
utilities. You can set the command line switches you want to use with these utilities by setting the
COPYCMD environment variable. Of course, you can always override your selections by specifying a
different set of command line switches at the command line. For example, if you set the /Y command
line switch in the COPYCMD environment variable, you can override it by specifying the /-Y
command line switch.
Many environment variables only affect one application. For example, you can set the MORE
environment variable to set the command line switches for the More utility.
