1 00:00:00,430 --> 00:00:02,070 Okay, so let's go and have a look at how 2 00:00:02,070 --> 00:00:07,340 we remove remote background jobs. Okay, so 3 00:00:07,340 --> 00:00:08,690 what we looked at last time was the 4 00:00:08,690 --> 00:00:11,020 creation of the jobs, but what about if we 5 00:00:11,020 --> 00:00:15,240 wanted to remove a specific job? Well, 6 00:00:15,240 --> 00:00:17,630 first off, we know that Get‑Job is going 7 00:00:17,630 --> 00:00:20,610 to retrieve any jobs, and we also know 8 00:00:20,610 --> 00:00:24,050 that if I say Remove‑Job, and pass in the 9 00:00:24,050 --> 00:00:27,110 Id, that that will clear those jobs down. 10 00:00:27,110 --> 00:00:30,640 And that's a local job. But what about a 11 00:00:30,640 --> 00:00:33,460 remote job? So let me go back into my 12 00:00:33,460 --> 00:00:35,190 session, and you can see I still have my 13 00:00:35,190 --> 00:00:40,380 existing session created. So how do I get 14 00:00:40,380 --> 00:00:45,370 those jobs from that remote machine? So 15 00:00:45,370 --> 00:00:48,890 what we can do here is I could say. let me 16 00:00:48,890 --> 00:00:52,180 just clear this, I could say $job, which 17 00:00:52,180 --> 00:00:53,400 is going to be the job that I want to get 18 00:00:53,400 --> 00:01:00,720 back. I could say Invoke‑Command, and I'm 19 00:01:00,720 --> 00:01:04,220 going to pass it into the session, so this 20 00:01:04,220 --> 00:01:07,030 session to the remote machine, and then 21 00:01:07,030 --> 00:01:09,750 I'm going to say ScriptBlock. And then of 22 00:01:09,750 --> 00:01:12,320 course we pass in some various options, 23 00:01:12,320 --> 00:01:15,460 and I'm going to say Get‑Job. So let's 24 00:01:15,460 --> 00:01:18,140 just execute that. Now what does that look 25 00:01:18,140 --> 00:01:20,560 like? Well, there we go. It brings back 26 00:01:20,560 --> 00:01:24,040 the job from the remote machine. So I 27 00:01:24,040 --> 00:01:27,110 basically invoke a command to use Get‑Job. 28 00:01:27,110 --> 00:01:29,480 So how do I remove that job because now 29 00:01:29,480 --> 00:01:32,260 I've got that one. What I can actually do 30 00:01:32,260 --> 00:01:39,200 is I can say $job, and if I say Get‑Job, 31 00:01:39,200 --> 00:01:40,970 and notice what happens, it says the 32 00:01:40,970 --> 00:01:43,470 command cannot find a job with the job ID 33 00:01:43,470 --> 00:01:46,160 1. That's because remember, where does job 34 00:01:46,160 --> 00:01:49,120 1 exist, not locally, and the standard 35 00:01:49,120 --> 00:01:52,400 Get‑Job command is tied to this local 36 00:01:52,400 --> 00:01:55,900 machine here. So how do we get rid of that 37 00:01:55,900 --> 00:01:59,000 specific one? Well, let's try doing job, 38 00:01:59,000 --> 00:02:02,180 and we'll do that. And then we'll say 39 00:02:02,180 --> 00:02:05,210 Remove‑Job, and we'll do that. Oh, wait, 40 00:02:05,210 --> 00:02:08,770 same issue. It comes back as a failure. So 41 00:02:08,770 --> 00:02:11,520 how do we clear the jobs down? Well, let's 42 00:02:11,520 --> 00:02:14,250 think about this. It's going to be where 43 00:02:14,250 --> 00:02:20,520 we can actually say Invoke‑Command, push 44 00:02:20,520 --> 00:02:23,200 it into the existing session on the remote 45 00:02:23,200 --> 00:02:27,510 one, say ScriptBlock, and then I'm going 46 00:02:27,510 --> 00:02:32,950 to say Remove‑Job ‑Id 1 because I already 47 00:02:32,950 --> 00:02:35,670 know that. Okay, so I initiated a 48 00:02:35,670 --> 00:02:39,840 connection, and I told it to remove. Now I 49 00:02:39,840 --> 00:02:42,310 have a connection here. So how do we get 50 00:02:42,310 --> 00:02:45,130 the jobs back for that? Well think of what 51 00:02:45,130 --> 00:02:47,460 we just did, we just did remove. We know 52 00:02:47,460 --> 00:02:51,810 that the Get‑Job command will return jobs, 53 00:02:51,810 --> 00:02:53,800 and sure enough, it's been deleted. So we 54 00:02:53,800 --> 00:02:56,790 can remove jobs utilizing the same 55 00:02:56,790 --> 00:02:59,450 mechanism that we did for creating of jobs 56 00:02:59,450 --> 00:03:02,140 and getting jobs from the remote machines. 57 00:03:02,140 --> 00:03:05,110 So when we execute the job on, you know, 58 00:03:05,110 --> 00:03:08,610 multiple computers, to retrieve or remove 59 00:03:08,610 --> 00:03:11,290 that, we need to go back into the existing 60 00:03:11,290 --> 00:03:16,000 session, so that we can then execute the commands using an invoke command.
