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:
  1. Successful completion.
