how to check size of a file in bash code example

Example 1: get file size in bash

# 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/

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

Example 2: bash size file

du -hs file/or/folder/path

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