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.
