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.
