# du is ok but is not accurate
# This is because it returns the disk usage for the target
# rather than the actual file size of the target.

# However, you can get more accurate results using the `--apparent-size` arg

du --apparent-size -h path/to/<file|folder>

# -h is tell it to print in a human readable format

-h for human readable
-s for summary: only total amount, not single files
