NAME

6       gc - count graph components
7

SYNOPSIS

9       gc [ -necCaDUrs?  ] [ files ]
10

DESCRIPTION

12       gc  is  a graph analogue to wc in that it prints to standard output the
13       number of nodes, edges, connected components or clusters  contained  in
14       the  input  files.  It also prints a total count for all graphs if more
15       than one graph is given.
16

OPTIONS

18       The following options are supported:
19
20       -n     Count nodes.
21
22       -e     Count edges.
23
24       -c     Count connected components.
25
26       -C     Count clusters. By definition, a cluster is a graph or  subgraph
27              whose name begins with "cluster".
28
29       -a     Count all. Equivalent to -encC
30
31       -r     Recursively analyze subgraphs.
32
33       -s     Print no output. Only exit value is important.
34
35       -D     Only analyze directed graphs.
36
37       -U     Only analyze undirected graphs.
38
39       -?     Print usage information.
40
41       By default, gc returns the number of nodes and edges.
42

OPERANDS

44       The following operand is supported:
45
46       files   Names  of  files containing 1 or more graphs in dot format.  If
47               no files operand is specified, the standard input will be used.
48

EXIT STATUS

50       The following exit values are returned:
51
52       0   Successful completion.
53
54       1   The -U or -E option was used, and a graph of  the  wrong  type  was
55           encountered.
