NAME

mkfile - create a file

SYNOPSIS

mkfile [-nv] size [g | k | b | m] filename...

DESCRIPTION

mkfile creates one or more files that are suitable for use as NFS-mounted
swap areas, or as local swap areas. When a root user executes mkfile(),
the sticky bit is set and the file is padded with zeros by default.
When non-root users execute mkfile(), they must manually set the sticky
bit using chmod(1). The default size is in bytes, but it can be flagged
as gigabytes, kilobytes, blocks, or megabytes, with the g, k, b, or m
suffixes, respectively.

OPTIONS

-n
Create an empty filename. 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.


-v
Verbose. Report the names and sizes of created files.

EXIT STATUS

The following exit values are returned:

0
Success.


>0
An error occurred.

USAGE

See largefile(7) for the description of the behavior of mkfile when
encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
