Run a remote command on all Jenkins slaves via Masters's script console

Question

I want to run same shell command (very simple shell commands like ls) on all the UNIX slaves which are connected to the master by using the master\'s script co

Until the end, I don't use * to search the agents, but instead I'm reading and parsing their names. For example, if I want to run a job on every agent that has LINUX in name, I will do next:

for (aSlave in hudson.model.Hudson.instance.slaves)
{
   /* take into account just agents with LINUX in name*/
   AGENT_NAME = aSlave.name
   if ( AGENT_NAME.contains('LINUX') )
   {
      /* you can check also if the agent is online or other attributes */

      /* Add agent name as label of the agent */ 
      AGENT_LABELS = aSlave.getLabelString() + " " + AGENT_NAME
      aSlave.setLabelString(AGENT_LABELS)


      /* For each found agent, create a job that will run on it */
      job('My_job_name_' + AGENT_NAME)
      {
          label(AGENT_NAME)
          steps {
               /* Do whatever you want here. 
                  This job will run just on this specific agent (due to label set) */
           }
      } 
   } /* end if */
} /* end for */  

/* If you want to run all jobs in parallel (every job on a specific agent), you can save all found agents in a list and then create one more pipeline job that will contain next line :

   ' parallel {
      b0: {build 'My_job_name_' + AGENT_NAME_LIST[0]},
      b1: {build 'My_job_name_' + AGENT_NAME_LIST[1]},
      ....
    }
    fastfail: false '
