Operating system-dependent variables and paths

This publication uses the UNIX® convention for specifying environment variables and for directory notation, except where the context or the example path is specifically Windows.

When using the Windows® command line, replace $variable with % variable% for environment variables and replace each forward slash (/) with a backslash (\) in directory paths. The names of environment variables are not always the same in Windows and UNIX environments. For example, %TEMP% in Windows is equivalent to $tmp in UNIX environments.
