xfs_mkfile(8)            System Manager's Manual            xfs_mkfile(8)

NAME top

       xfs_mkfile - create an XFS file

SYNOPSIS top

       xfs_mkfile [ -v ] [ -n ] [ -p ] size[k|b|m|g] filename ...
       xfs_mkfile -V

DESCRIPTION top

       xfs_mkfile creates one or more files. The file is padded with
       zeroes by default.  The default size is in bytes, but it can be
       flagged as kilobytes, blocks, megabytes, or gigabytes with the k,
       b, m, or g suffixes, respectively.

OPTIONS top

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

       -n     No bytes. Create a holey file - that is, do not write out
              any data, just seek to end of file and write a block.

       -p     Preallocate.  The file is preallocated, then overwritten
              with zeroes, then truncated to the desired size.

       -V     Prints the version number and exits.
