Normally options and operands can appear in any order, and programs
act as if all the options appear before any operands. For example,
‘sort -r passwd -t :’ acts like ‘sort -r -t : passwd’, since ‘:’ is an
option-argument of ‘-t’. However, if the ‘POSIXLY_CORRECT’ environment
variable is set, options must appear before operands, unless otherwise
specified for a particular command.
