Conditions

In a command file, commands and/or parameters can be connected with conditions when needed to run or apply them.A condition is labelled with the string "CONDITION".The following operations can be used for getting a verification of validity:

  • the values are equal- ("==")
  • the values are unequal- („!=“)
  • the left value is greater than the right value (">")
  • the left value is smaller than the right value ("<")

A dynamic command file processing can be attained by evaluating the environment variables in conditions.

Example
<command name="create partition"> <CONDITION> $ENV:(ImageStep)==2</CONDITION> <drivenumber>0</drivenumber> <!—target object is disk 0 --> <remaining_range>true</remaining_range> <!-- layout of a partition on the remaining range --> <driveletter_to_set>D</driveletter_to_set> <!—set drive letter D --> <chs_alignment>yes</chs_alignment> <!—alignment of the new partition on cylinder/head/sector --> <NTFS>true</NTFS> <!—create NTFS partition (fix partition type, fix file system for formatting) --> <format>true</format> <!—run formatting with fixed file system --></command>

In the above example, the command to create a partition will only be run if the value of the environment variable "ImageStep" is equal to the value "2".
