### 6.1.5. Operating System Names

When we refer to objects that depend on the type of system being used, we will use one of the following symbols in the text:

`<os>` refers to the short form of the name which CFX uses to identify the operating system in question. `<os>` will generally be used for directory names where the contents of the directory depend on the operating system but do not depend on the release of the operating system or on the processor type. Wherever you see `<os>` in the text you should substitute with the operating system name. The correct value can be determined by running:

`<CFXROOT>/bin/cfx5info -os`

`<arch>` refers to the long form of the name that CFX uses to identify the system architecture in question. <arch> will generally be used for directory names where the contents of the directory depend on the operating system and on the release of the operating system or the processor type. Wherever you see `<arch>` in the text you should substitute the appropriate value for your system, which can be determined by running the command:

`<CFXROOT>/bin/cfx5info -arch`
