specified via those options. This option is useful when you have
many fields and want to print all but a few of them.
@optItem{cut,-d,@w{ }@var{character}}
@optItemx{cut,--delimiter,=@var{character}}
With @option{-f}, use @var{character} as
the input field separator (default is TAB).
If an empty delimiter @var{character} is specified then the ASCII NUL
character is used to delimit the fields.
Note the delimiter @var{character} can be the same as the
line terminator character, which can be used to select ranges of lines.
In this case the last line terminator in the input is not treated
as a field separator, which is significant with the @option{-s} option.
@optItem{cut,-f,@w{ }@var{field-list}}
@optItemx{cut,--fields,=@var{field-list}}
Select for printing only the fields listed in @var{field-list}.
