string split [(-m | --max) MAX] [(-n | --no-empty)] [(-q | --quiet)] [(-r | --right)] SEP [STRING...] string split0 [(-m | --max) MAX] [(-n | --no-empty)] [(-q | --quiet)] [(-r | --right)] [STRING...]
string split splits each STRING on the separator SEP, which can be an empty string. If
--max is specified, at most MAX splits are done on each STRING. If
--right is given, splitting is performed right-to-left. This is useful in combination with
--no-empty, empty results are excluded from consideration (e.g.
hello\n\nworld would expand to two strings and not three). 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.
