APPLICATION USAGE. Use of the macros is recommended for determining the type of a file. RATIONALE. A conforming C-language application must include <sys/stat.h> for functions that have arguments or return values of type mode_t, so that symbolic values for that type can be used.An alternative would be to require that these constants are also defined by including …

POSIX, this is a set of standards specified by IEEE to maintain compatibility between operating systems. One of which is the definition of a "line" being a sequence of zero or more non- characters plus a terminating newline character. So for that last line to be recognised as an actual "line" it should have a terminating new line character.

ls -lh gives human readable file sizes, long format.. ls from the GNU coreutils package gives sizes in binary byte format in this case, e.g. Mebibyte (MiB), which is strongly endorsed by IEEE and CIPM instead of Megabyte (MB).. It uses k, M, G, and T suffixes (or no suffix for bytes) as needed so the number stays small, e.g. 1.4K or 178M.-h is a GNU coreutils extension, not baseline POSIX.
