Create random file.

  • Create a file of size 1MB containing random bytes:

    create_random_file( name => "file1", size => "1M");
  • Like the previous example (--random-bytes is optional):

    create_random_file( name => "file2", size => "2M", random_bytes => 1);
  • Create a file of size 3.5KB containing repeated pattern:

    create_random_file( name => "file3", size => "3.5K", patterns => ["AABBCC"]);
  • Create a file of size 4KB containing random sequences of A, B, C:

    create_random_file( name => "file4", size => "4K", patterns => ["A", "B", "C"]);

Create "random" file with a specified size. There are several choices of what random data to use:

  • random bytes, created using rand()

  • repeated pattern supplied from --pattern command-line option

TODO:

  • random bytes, source from /dev/urandom

  • random lines from a specified file

  • random byte sequences from a specified file

    Whether to overwrite existing file.

    If se to true then will overwrite existing file without warning. The default is to prompt, or bail (if not interactive).

  • patterns => array[str]

  • random_bytes => bool

  • size* => str

    Size (e.g. 10K, 22.5M).

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error).
