DESCRIPTION

12              Sum lines matching specified formats.
13
14       Any number of input files can be given.
15              "-" means stdin.
16
17              If  there are no files given, just stdin is assumed.  File names
18              can contain wildcards, in which case all matching files
19
20              are used in numerically sorted order.
21
22              Formats are read from four sources in this order: (1) Any  files
23              mentioned  with  -f  on  the command line (any number).  (2) The
24              file named in the environment variable SUMLINES.FMT (if any) (3)
25              The  file  sumlines.fmt  in the current directory (if it exists)
26              (4) The file sumlines.fmt in the home directory (if  it  exists)
27              All  these  are read if they exist and the results concatenated.
28              Formats exactly matching earlier  formats  (except  perhaps  for
29              flags)
30
31              are not used.
32
33       Each format occupies exactly two lines.
34              The first line gives a
35
36              list of flags (DEFAULT FINAL ERROR UNIQUE COUNT CONTINUE NUMERIC
37              SILENT ENDFILE P=# NOPREFIX BEFORE/.../ AFTER/.../ separated  by
38              spaces, commas or |s).  The second line gives the format itself.
39
40       Example.
41              This totals the summary lines of autoson runs:
42
43       DEFAULT
44              # comment
45
46       cpu=%fu,%fs,%fx
47              pf=%d
48
49              There  can also be blank lines and lines with only comments, but
50              not between the flags line and the format itself.
51
52       -d don't read sumlines.fmt or ~/sumlines.fmt or $SUMLINES.FMT
53
54       -w suppresses warning messages about no matching lines or no
55
56              matching final lines.
57
58       -W in addition, suppresses warning about missing cases.
59
60       -n don't write the number of matching lines for each format.
61
62       -v produces a list of all the formats.
