Clear Linux* OS offers many types of images for different platforms and environments.

The naming convention of a Clear Linux OS image filename is:

clear-[version number]-[image type].[compression type]
  • The [version number] field specifies the version number.
  • The [image type] field specifies the type of image and its corresponding file format.
  • The [compression type] field specifies the compression type. Two types of compressions are used: GNU* zip (.gz) and XZ (.xz).

Table 1 lists the currently available images that are platform independent. Table 2 lists the currently available images that are platform specific.
