Detailed Description

Implements the fill command for the BSFS browser.

The fill command creates a number of files with a given size, measuring the elapsed time for the operation. Files are created sequentially using the high-level API and filled with a predictable byte pattern.

Usage: fill <count> <size> [prefix] [bs=<block>] [pattern=index|zero|random]

Parameters:

• count : number of files to create (positive integer)
• size : file size (supports K/M/G suffixes)
• prefix : optional basename/path (default: "fill") used to build <prefix>_<NNN>.bin
• bs= : optional block size for writes (default 64 KiB, supports suffixes)
• pattern : optional fill pattern: "index" (default, byte = file id), "zero" (all zeros) or "random" (pseudo-random bytes)
