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, repreā
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.
31

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.

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.
