**NAME**

botch-graph-shortest-path - find the shortest path(s) between two vertices of a graph in GraphML or dot format

**SYNOPSIS**

botch-graph-shortest-path[options] --sourceSOURCE[--sourceSOURCE...] --targetTARGET[--targetTARGET...] [ingraph] [outgraph]

**DESCRIPTION**

Extract the subgraph of the shortest path between two specific nodes in the input graph. The--targetand--sourceoptions are mandatory and can be specified more than once. 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.

**OPTIONS**

-h,--helpDisplay help.--target=TARGETThis option picks the target vertex. The TARGET argument is a key/value pair (separated by a colon) of a graph attribute and its desired value. If more than one vertex matches the given key/value pair, then the smallest (by node comparison) is chosen. The special key "__ID__" allows one to select the unique vertex identifier. This option can be specified more than once. The final set of vertices is chosen such that all vertices match all key/value pairs. Multiple--targetoptions thus form a logical conjunction (they are AND-ed together).--source=SOURCEThis option picks the source vertex. The SOURCE argument is a key/value pair (separated by a colon) of a graph attribute and its desired value. If more than one vertex matches the given key/value pair, then the smallest (by node comparison) is chosen. The special key "__ID__" allows one to select the unique vertex identifier. This option can be specified more than once. The final set of vertices is chosen such that all vertices match all key/value pairs. Multiple--sourceoptions thus form a logical conjunction (they are AND-ed together).--allinstead of finding an arbitrary shortest path, find all shortest paths-v,--verboseBe verbose.

**EXAMPLE**

Extract the subgraph of the shortest path from a certain version of the build-essential binary vertex to a certain version of the ghc source vertex. botch-graph-shortest-path --source name:build-essential --source version:11.7 --source type:bin --target name:ghc --target version:7.8.4-8 --target type:src < in.xml > out.xml or giving input and output as positional arguments: botch-graph-shortest-path --source name:build-essential --source version:11.7 --source type:bin --target name:ghc --target version:7.8.4-8 --target type:src in.xml out.xml
