GC(1) General Commands Manual GC(1) NAME gc - count graph components SYNOPSIS gc [ -necCaDUrsv? ] [ 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. -v Verbose output. -? 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. AUTHOR Emden R.
