``string split`` splits each STRING on the separator SEP, which can be an empty string. If ``-m`` or ``--max`` is specified, at most MAX splits are done on each STRING. If ``-r`` or ``--right`` is given, splitting is performed right-to-left. This is useful in combination with ``-m`` or ``--max``. With ``-n`` or ``--no-empty``, empty results are excluded from consideration (e.g. ``hello\n\nworld`` would expand to two strings and not three). Use ``-f`` or ``--fields`` to print out specific fields. Exit status: 0 if at least one split was performed, or 1 otherwise.
``string split0`` splits each STRING on the zero byte (NUL). Options are the same as ``string split`` except that no separator is given.
``split0`` has the important property that its output is not further split when used in a command substitution, allowing for the command substitution to produce elements containing newlines. This is most useful when used with Unix tools that produce zero bytes, such as ``find -print0`` or ``sort -z``. See split0 examples below.
