Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
redis-check-aof -V (return code: 1)
Cannot open file: --version
redis-check-aof (return code: 1)
Usage: redis-check-aof [--fix] <file.aof>
