NAME

       nauty-sumlines - sum lines matching specified graph formats

SYNOPSIS

       sumlines [-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.

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

       -v produces a list of all the formats.
