This is the command botch-graph-sinks that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
botch-graph-sinks - find all sinks (vertices without successors) in a graph in GraphML or
botch-graph-sinks [options] [ingraph] [outgraph]
Extract the subgraph of all sinks (vertices without successors) in the input graph.
If either (or both) of the positional arguments is/are omitted, then read GraphML or dot
from standard input and/or write GraphML or dot to standard output, respectively. Passing
a '-' as either argument, explicitly specifies to read the input from standard input and
write the output to standard output, respectively.
The input graph type will be determined automatically. If the output graph is given as a
filename, then the output type will be GraphML if the filename ends with .xml and dot if
the filename ends with .dot. If the output is done on standard output then it will happen
in the same format as the input graph.
