Translation occurs if <B>-d</B> is not given and both SET1 and SET2 appear.
|
|
<B>-t</B> may be used only when translating. SET2 is extended to length of
|
|
SET1 by repeating its last character as necessary. Excess characters
|
|
of SET2 are ignored. Only [:lower:] and [:upper:] are guaranteed to
|
|
expand in ascending order; used in SET2 while translating, they may
|
|
only be used in pairs to specify case conversion. <B>-s</B> uses the last
|
|
specified SET, and occurs after translation or deletion.
