.SH DESCRIPTION

.SH OPTIONS
|
||
|
|
Below is a summary of all the options that
|
||
|
|
.B ntfstruncate
|
||
|
|
accepts. Nearly all options have two equivalent names. The short name is
|
||
|
|
preceded by
|
||
|
|
.B \-
|
||
|
|
and the long name is preceded by
|
||
|
|
.BR \-\- .
|
||
|
|
Any single letter options, that don't take an argument, can be combined into a
|
||
|
|
single command, e.g.
|
||
|
|
.B \-fv
|
||
|
|
is equivalent to
|
||
|
|
.BR "\-f \-v" .
|
||
|
|
Long named options can be abbreviated to any unique prefix of their name.
|
||
|
|
.TP
|
||
|
|
\fB\-f\fR, \fB\-\-force\fR
