       nauty-sumlines - sum lines matching specified graph formats

SYNOPSIS

       sumlines [-w|-W] [-v] [-d] [-n] [-f fmtfile]...  file file file ...

DESCRIPTION

              Sum lines matching specified formats.

       Any number of input files can be given.
              "-" means stdin.

              If  there  are  no files given, just stdin is assumed.  File names can contain wildcards, in which
              case all matching files

              are used in numerically sorted order.

              Formats are read from four sources in this order: (1) Any files mentioned with -f on  the  command
              line  (any  number).  (2) The file named in the environment variable SUMLINES.FMT (if any) (3) The
              file sumlines.fmt in the current directory (if it exists) (4) The file sumlines.fmt  in  the  home
              directory  (if  it exists) All these are read if they exist and the results concatenated.  Formats
              exactly matching earlier formats (except perhaps for flags)

              are not used.

       Each format occupies exactly two lines.
              The first line gives a

              list of flags (DEFAULT FINAL ERROR UNIQUE COUNT CONTINUE NUMERIC SILENT ENDFILE P=#  separated  by
              spaces, commas or |s).  The second line gives the format itself.

       Example.
              This totals the summary lines of autoson runs:

       DEFAULT
              # comment

       cpu=%fu,%fs,%fx
              pf=%d

              There can also be blank lines and lines with only comments, but not between the flags line and the
              format itself.

       -d don't read sumlines.fmt or ~/sumlines.fmt or $SUMLINES.FMT

       -w suppresses warning messages about no matching lines or no

              matching final lines.

       -W in addition, suppresses woarning about missing cases.

       -n don't write the number of matching lines for each format.

       -v produces a list of all the formats.
