srf_info(1)			 Staden	io_lib			   srf_info(1)

NAME
       srf_info	- Lists	information about the contents of an SRF file

SYNOPSIS
       srf_info	 [-l bitmap] srf_archive ...

DESCRIPTION
       srf_info	 lists some simple frequency metrics on	the contents of	an SRF
       file, both in terms of how many traces there are	and the	sort  of  data
       held within them.

       For  efficiencies  sake	some control is	given over which statistics to
       gather and display. This	is controlled by the -l	level  parameter.  The
       value  is  the summation	of one or more of the following	values,	repre-
       senting the data	to display.

       1      Count of good/bad	reads.

       2      Counts and compressed size for selected chunk types.

       4      Trace count and trace name prefix	for each trace_header.

       8      Base count.

OPTIONS
       -l bitmap
	      Controls which statistics	to gather and  display.	 Bitmap	 is  a
	      value  from  0  to  15 (1+2+4+8) as described in the DESCRIPTION
	      section above.

EXAMPLES
       To count	the total number of good and bad reads along with a break down
       of  trace  names	per SRF	data-block-header we would use bitmap values 1
       and 4 combined.

	   srf_info -l 5 foo.srf

       To count	the total number of reads for all srf files in a directory.

	   srf_info -l 1 *.srf
