+.TH MKFILE 8 "1 September 1997"
+.SH NAME
+mkfile \- create a file
+.SH SYNOPSIS
+.B mkfile
+.RB [ " -nv " ]
+.I size\c
+[\c
+.BR b | k | m | g\c
+]
+.IR filename " .\|.\|."
+.SH DESCRIPTION
+.B mkfile
+creates one or more files that are suitable for use as
+.SM NFS-\s0mounted
+swap areas.  The sticky bit is set, and
+the file is padded with zeroes by default.
+Non-root users must set the sticky bit using
+chmod(1).
+The default size unit is bytes, but the following suffixes
+may be used to multiply by the given factor:
+.B b
+(512),
+.B k
+(1024),
+.B m
+(1048576), and
+.B g
+(1073741824).
+.SH OPTIONS
+.TP
+.B \-n
+Create an empty
+.IR filename .
+The size is noted, but disk blocks aren't allocated until data is
+written to them.
+.TP
+.B \-v
+Verbose.  Report the names and sizes of created files.
+.SH WARNING
+If a client's swap file is removed and recreated, it must be
+re-exported before the client will be able to access it.
+This action may only be done when the client is not running.
+.SH "SEE ALSO"
+.TP
+chmod(2), stat(2), sticky(7)
