grph has-path

Check if a path exists between two nodes.

Synopsis​

grph has-path <file> <source> <target>

Description​

The has-path command quickly checks whether any path exists between two nodes. This is faster than grph path when you only need to know if connectivity exists.

Arguments​

ArgumentDescription
filePath to the GEXF file (required)
sourceID of the starting node (required)
targetID of the destination node (required)

Examples​

Basic Usage​

grph has-path network.gexf lb1 db1

Output (if path exists):

Yes - a path exists from lb1 to db1

Output (if no path):

No - no path exists from lb1 to db1

Use Cases​

Connectivity Check​

Verify two components can communicate:

grph has-path network.gexf client server

Dependency Verification​

Check if a dependency relationship exists:

grph has-path dagger-graph.gexf FeatureModule CoreLibrary

Scripting​

Use in scripts for conditional logic:

if grph has-path graph.gexf nodeA nodeB 2>&1 | grep -q "Yes"; then
  echo "Connected"
