+.TH iofileb.d 1m "$Date:: 2007-08-05 #$" "USER COMMANDS"
+.SH NAME
+iofileb.d \- I/O bytes by file and process. Uses DTrace.
+.SH SYNOPSIS
+.B iofileb.d
+.SH DESCRIPTION
+This prints a summary of requested disk activity by pathname,
+providing totals of the I/O events in bytes. It is a companion to the
+iofile.d script - which prints in terms of I/O wait time, not bytes.
+I/O wait time is a better metric for understanding performance issues.
+Both disk and NFS I/O are measured.
+
+Since this uses DTrace, only the root user or users with the
+dtrace_kernel privilege can run this command.
+.SH OS
+Solaris
+.SH STABILITY
+stable - needs the io provider.
+.SH EXAMPLES
+.TP
+Sample until Ctrl\-C is hit then print report,
