Description

GC(1)                       General Commands Manual                      GC(1)



NAME
       gc - count graph components

SYNOPSIS
       gc [ -necCaDUrs?  ] [ files ]

DESCRIPTION
       gc  is  a graph analogue to wc in that it prints to standard output the
       number of nodes, edges, connected components or clusters  contained  in
       the  input  files.  It also prints a total count for all graphs if more
       than one graph is given.

OPTIONS
       The following options are supported:

       -n     Count nodes.

       -e     Count edges.

       -c     Count connected components.

       -C     Count clusters. By definition, a cluster is a graph or  subgraph
              whose name begins with "cluster".

       -a     Count all. Equivalent to -encC

       -r     Recursively analyze subgraphs.

       -s     Print no output. Only exit value is important.

       -D     Only analyze directed graphs.

       -U     Only analyze undirected graphs.

       -?     Print usage information.

       By default, gc returns the number of nodes and edges.

OPERANDS
       The following operand is supported:

       files   Names  of  files containing 1 or more graphs in dot format.  If
               no files operand is specified, the standard input will be used.

EXIT STATUS
       The following exit values are returned:

       0   Successful completion.

       1   The -U or -E option was used, and a graph of  the  wrong  type  was
           encountered.
