"size in bytes"
Code:
-l Lists in long format, giving mode, ACL indica-
tion, number of links, owner, group, size in
bytes, and time of last modification for each
file (see above). If the file is a special
file, the size field instead contains the major
and minor device numbers. If the time of last
modification is greater than six months ago, it
is shown in the format `month date year' for
the POSIX locale. When the LC_TIME locale
category is not set to the POSIX locale, a dif-
ferent format of the time field can be used.
Files modified within six months show `month
date time'. If the file is a symbolic link, the
filename is printed followed by "->" and the
path name of the referenced file.
