Use built-in unix command `stat` instead of `exiftool`

The part you want to Enhancement

We can get file attributes without additional programs, but use the built-in stat utility.

Why it is necessary to enhancement

We won't need to install a third party program.

Additional context

Windows also has an alternative command: Windows equivalent to the unix "stat" command?. You may also find this useful: stat(1) — Linux manual page.

Here's what it looks like on macOS and ubuntu. You can also specify the output format you want via the --format argument.

Looks great. It will be better if we don't need to install another tool.
