PROGRAM:

NAME


bcomps - biconnected components filter for graphs

SYNOPSIS


bcomps [ -stvx? ] [ -ooutfile ] [ files ]

DESCRIPTION


bcomps decomposes graphs into their biconnected components, printing the components to
standard output.

OPTIONS


The following options are supported:

-s No output graph is printed. Implies the -v flag.

-t Print the underlying block-cutvertex tree.

-x Each biconnected component is printed as a separate root graph.

-v Prints number of blocks and cutvertices.

-o outfile
If specified, each root graph will be written to a different file with the names
derived from outfile. In particular, if both -o and -x flags are used, then each
block is written to a different file. If outfile does not have a suffix, the nth
block of the ith graph is written to outfile_n_i. However, the 0th block of the 0th
graph is written to outfile.

If outfile has a suffix, i.e., has the form base.sfx, then the files will have the
same name as above, except appended with .sfx.

The block-cutvertex tree of ith graph is written to outfile_n_T, with an appended
suffix if specified.

By default, each input graph is printed, with each block given as a subgraph whose name is
a concatenation of the name of the input graph, the string "_bcc_" and the number of the
block.

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.

RETURN CODES


bcomps returns 0 if all the input graphs are biconnected; and non-zero if any graph has
multiple blocks, or any error occurred.
