Get Properties of Free Nodes in PBS

This bash script retrieves and displays the properties of all free nodes in a PBS (Portable Batch System) cluster.

Usage:

Save the script to a file (e.g., free_node_properties.sh) and make it executable (chmod +x free_node_properties.sh). Then, run the script:

./free_node_properties.sh

Output:

The script will print the name of each free node followed by its "state = free" line and its "properties = ..." line, indented for readability. For example:

s001-n086
     state = free
     properties = xeon,skl,gold6128,ram192gb,net1gbe,fpga_runtime,fpga,arria10

s001-n087
     state = free
     properties = xeon,cfl,e-2176g,ram64gb,net1gbe,gpu,gen9

...

How it Works:

1. The script uses pbsnodes -l free to get a list of free nodes.
2. For each free node:
   • It runs pbsnodes <node_name> to get the node's detailed information.
   • It uses awk to extract and print the "state = free" and "properties = ..." lines.

Note:

This script assumes that the pbsnodes command is available in your environment.
