Explanation for some commands

Hello

I am new to poewrcli and will work with her over the next while. Can someone explain the following for me please? If someone could put beside each line comments to explain the syntax in its entirety, it would be great. This isn't just a script, it is a mixture of different lines that I don't understand

  • Plugin Check gives poor results for some Mac

    On a Mac under OS X 10.6.8 (Snow Leopard) or versions earlier, Plugin check mark indicates the Applet Java plug-in and QuickTime plug-ins are obsolete.

    Steps to reproduce:
    Tools-> Add-ons-> Plugins-> check to see if your plugins are up to date

    The results show:
    Java Applet plugin update now
    QuickTime plugin 7.6.6 update now

    Explanation:
    1. before Apple OS X 10.7 (Mountain Lion) provided Java. Apple did not provide an update. [thejava.com siteupdate requires Mac OS X (10.7.3 version and above)]
    2. There is no update QuickTime plugin 7.6.6 for some Mac; It is a more recent OS x 10.6.3 via 10.6.8.

    Plugin Check can be fixed?

  • RemoteScan is not for some users

    I recently installed RemoteScan on a new machine and got all this work in one programs installed on the RDS Server. In the other program requiring analysis, RemoteScan appears only for some users. I tried to recreate the user profile. I tried to copy it to the file remote.ini of a profile that works. I tried to reinstall RemoteScan on the workstation, but so far nothing has solved the problem. I have no idea what could be the cause and was hoping that someone could have encountered the same problem. Any help would be greatly appreciated.

    RemoteScan files must be in the user homepath. These files should be as follows:

    TWAIN_32 (folder... RemoteScan internal folder)
    TWAIN_32.dll 44KO
    Twunk_32.exe

    All these RemoteScan files should be in the folder windows homepath from the user. To confirm the homepath from the user, you need to connect to the server as the user and then display a command prompt. Type set home.

    If you have questions contact RemoteScan to 406-721-0276.

    (1) you have a third-party security software installed?
    This could be due to that... What are the analyses of different viruses that you already have... It may be a product of firewall or security of third parties that interfere the windows firewall, disable one by one your security scanners and try for windows firewall

    (2)if you do not have these installed firewall products, this could be due to malicious software or some other problem...

    If you have an antivirus up to date solution its definitions and do a full scan of the system...

  • See load test: ways to script for applications commands?

    Hello

    I'm designing a simple tool for an environment of view and so far its goes pretty well load test.  With the help of command line arguments and some Powershell, I am capable of recursion through a list of users and connect multiple sessions on a display server and open office and a few RDS App sessions.  My question is: is there a built-in way to pass a script in the command line arguments run certain commands on this computer to office or RDS App session?  Nothing crazy, just type in Notepad, open a few programs, save a doc or two--the usual stuff to generate regular workloads.

    I know that VMware and third party companies have tools for this, but they don't specifically meet my needs without extensive configuration and a lot of hooks in our systems.  I'm trying to keep the footprint of this test as small as possible, so a simple Powershell script is how I want to move forward.  I guess that Powershell has a method to do this, but I'm not guru script nor it is a PS forum, so I was hoping there was something that already exists when I call the view connection that I could use.

    Any help is appreciated, thanks in advance!

    I can not completely solve your problem, but it can be a little simpler.

    Q. for the "is there a built-in way to pass a script in the command line arguments run certain commands on this computer to office or RDS App session?

    A. No, but you can use strategies Group (GPO) that can be activated when his connection to run a script.

    BTW, for others who read this blog, "VMware View Planner" is the internal tool that can be used by customers too much for some areas of load test: VMware View Planner | United States

    I found that if it becomes necessary to use time machine to return to an earlier existence to reinstall the iphoto library, if for some reason, you lose lose, then when you try to synchronize your ipad is not recognized by the computer.  So when you try to synchronize the pictures, they are all removed from the ipad and trying to reinstall everything again.

    This may or may not work immediately.  In my case, only half the photos have been installed, and then the error message came that the rest of 9000 can be installed.

    I contacted Apple support team who has made various suggestions.  Subsequently clicking on a photo list in iTunes were all going again and pictures of 9000 then installed.  When I asked the support team what could happen I was told that it was a "glitch".  I don't like seeds they mean that there could be an error in coding somewhere.

  • The numbers "could not open file for some reason any."

    Suddenly some of my documents of numbers prompt response "numbers" could not open file for some reason any ' "the document is unavailable. Other documents numbers remain accessible. My backup versions invites the same response when I try to open them. Is there a solution?

    Hello Fred,.

    Thanks for this info and choosing the communities Support from Apple. I know how important is able to open all your files in numbers is for you!

    If I understand correctly, you cannot open some files of numbers even from backups, but others continue to work. To limit this problem, I would suggest starting with the following steps:

    1. first of all, run disk utility and check for questions on your hard drive, as hard drive problems can lead to situations like yours.

    Disk utility (Yosemite): a disc repair

    2. then, you can test this in a new user, to refine, if it's a question broad system or specific to your username.
