NAME

SYNOPSIS

10       srf_info  [-l bitmap] srf_archive ...
11
12

DESCRIPTION

14       srf_info  lists some simple frequency metrics on the contents of an SRF
15       file, both in terms of how many traces there are and the sort  of  data
16       held within them.
17
18       For  efficiencies  sake  some control is given over which statistics to
19       gather and display. This is controlled by the -l level  parameter.  The
20       value  is  the summation of one or more of the following values, repre‐
21       senting the data to display.
22
23
24       1      Count of good/bad reads.
25
26       2      Counts and compressed size for selected chunk types.
27
28       4      Trace count and trace name prefix for each trace_header.
29
30       8      Base count.

OPTIONS

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

EXAMPLES

41       To count the total number of good and bad reads along with a break down
42       of  trace  names per SRF data-block-header we would use bitmap values 1
43       and 4 combined.
44
45           srf_info -l 5 foo.srf
46
47
48       To count the total number of reads for all srf files in a directory.
