[%CFEngine_function_prototype(file, algorithm)%]
Description: Return the hash of file using the hash algorithm.
This function is much more efficient that calling hash() on a string
with the contents of file.
Hash functions are extremely sensitive to input. You should not expect to get the same answer from this function as you would from every other tool, since it depends on how whitespace and end of file characters are handled.
[%CFEngine_function_attributes(file, algorithm)%]
Example:
Prepare:
[%CFEngine_include_snippet(filestat.cf, #+begin_src prep, .*end_src)%]
Run:
[%CFEngine_include_snippet(file_hash.cf, #+begin_src cfengine3, .*end_src)%]
Output:
[%CFEngine_include_snippet(file_hash.cf, #+begin_src\s+example_output\s*, .*end_src)%]
History: Introduced in CFEngine 3.7.0
