stat

Display file status. More information: https://keith.github.io/xcode-man-pages/stat.1.html.

Show file properties such as size, permissions, creation and access dates among others:

stat {{path/to/file}}

Same as above but verbose (more similar to Linux's stat):

stat -x {{path/to/file}}

Show only octal file permissions:

stat -f %Mp%Lp {{path/to/file}}

Show owner and group of the file:

stat -f "%Su %Sg" {{path/to/file}}

Show the size of the file in bytes:

stat -f "%z %N" {{path/to/file}}
