|

|
<P>
|
|
|
|
Shrink or extend the size of each FILE to the specified size

<P>
|
|
|
|
If a FILE is larger than the specified size, the extra data is lost.
|
|
If a FILE is shorter, it is extended and the extended part (hole)
|
|
reads as zero bytes.
|
|
<P>
|
|
|
|
Mandatory arguments to long options are mandatory for short options too.
