.SH NAME
mkfile \- create a file
.SH SYNOPSIS
.LP
.nf
\fBmkfile\fR [\fB-nv\fR] \fIsize\fR [g | k | b | m] \fIfilename\fR...
.fi

.SH DESCRIPTION
.sp
.LP
\fBmkfile\fR creates one or more files that are suitable for use as
\fBNFS-mounted\fR swap areas, or as local swap areas. When a root user executes
\fBmkfile()\fR, the sticky bit is set and the file is padded with zeros by
default.   When non-root users execute  \fBmkfile()\fR, they must manually set
the sticky bit using  \fBchmod\fR(1). The default \fBsize\fR is in bytes, but
it can be flagged as gigabytes, kilobytes, blocks, or megabytes, with the
\fBg\fR, \fBk\fR, \fBb\fR, or \fBm\fR suffixes, respectively.
.SH OPTIONS

Create an empty \fIfilename\fR. The size is noted, but disk blocks are not
allocated until data is written to them. Files created with this option cannot
be swapped over local UFS mounts.
