program shrinks files to a given
if the size is larger than
preserving the data at the end of the file.
Truncation is performed on line boundaries, where a line is a series
of bytes ending with a newline, \n.
There is no line length restriction and files may contain any binary data.
Temporary files are created in the

The ``TMPDIR'' environment variable may be used to specify a
A newline will be added to any non-empty file that does not end with a newline.
The maximum file size will not be exceeded by this addition.

The ``-s'' flag may be used to change the truncation size.
Because the program truncates only on line boundaries, the final size
may be smaller then the specified truncation size.
parameter may end with a ``k'', ``m'', or ``g'', indicating
kilobyte (1024), megabyte (1048576) or gigabyte (1073741824) lengths.
Uppercase letters are also allowed.
The maximum file size is 2147483647 bytes.
If the ``-v'' flag is used, then
will print a status line if a file was shrunk.
If the ``-n'' flag is used, then
will exit 0 if any file is larger than
and exit 1 otherwise.
No files will be altered.
