Version : Thu Jul 24 22:50:17 JST 2014

Description

Splits the specified <field> into two fields of length <length>.

The length is display width (half width character = 1). If a

multi-byte character will be split in the middle of a chracter

then the field is split at the bigining of that character.

If you specify a length so that the field cannot be split, then

one field is output as "_".

The -b option uses byte length instead of display width.

The -c option uses number of characters instead of display width.
