PowerShell files for all versions are .ps1 (or .psm1, .psd1, etc.).

I had a file called `example_file.py`, which I wanted to use from various other files, so I decided to add `example_file.py` to `sys.path` and import this file in another file to use the file. To do so, I ran the following in IPython.

    import sys
    sys.path
    sys.path.append(&#39;/path/to/the/example_file.py&#39;)
    print(sys.path)

I could see the path I had just added, and when I tried to import this file from another directory path like this:

    import example_file

it worked just fine, but once I came out of IPython, entered it again, and checked the `sys.path`, I saw that the path which I had added was not present, so how do I add a path to sys.path permanently in Python?

Note, I do NOT want millis from epoch. I want the number of milliseconds currently on the clock.

So for example, I have this bit of code.

    Date date2 = new Date(); 
    Long time2 = (long) (((((date2.getHours() * 60) + date2.getMinutes())* 60 ) + date2.getSeconds()) * 1000);
		
Is there a way to get milliseconds with date?
Is there another way to do this?

**Note:** `System.currentTimeMillis()` gives me millis from epoch which is not what I&#39;m looking for.

How can I get the count of milliseconds since midnight for the current?

All of us probably know `.bat` for Batch files.

But what is the file extension for **PowerShell 3** scripts?

I found `.ps1` and some other endings but they&#39;re only for version 1.

I need to execute **ssh** from **windows command line** by providing password in a non interactive manner. I could implement the key based authentication and able to execute the ssh commands just like 

    ssh &lt;user&gt;@&lt;host&gt; &lt;command&gt;

Is there any commands like 

    ssh &lt;user&gt;@&lt;host&gt; -P &lt;password&gt; &lt;command&gt;

I want to retrieve the FQDN name of windows server via powershell script. I have found 2 solution so far:

    $server =  Invoke-Command -ScriptBlock {hostname}

Above line will print just the short name of the server

    $sysinfo = Get-WmiObject -Class Win32_ComputerSystem
    $server = “{0}.{1}” -f $sysinfo.Name, $sysinfo.Domain

Above two line will get me the FQDN but this looks really nasty code to retrieve just the hostname :(

So, My question is, is there an easier way to get the FQDN in powershell. I am a bash/perl coder and recently picked up powershell.. so finding it difficult.

Thanks.

I&#39;ve been writing some batch files, and I ran into [this user guide](http://www.tacktech.com/display.cfm?ttid=307), which has been quite informative. One thing it showed me was that lines can be commented not just with `REM`, but also with `::`. It says:

&gt; Comments in batch code can be made by using a double-colon, this is better than using the REM command because labels are processed before redirection symbols. `::&lt;remark&gt;` causes no problems but `rem &lt;remark&gt;` produces errors. 

Why then, do most guides and examples I see use the `REM` command? Does `::` work on all versions of Windows?

Which comment style should I use in batch files?

I have to write a function in bash. The function will take about 7 arguments. I know that I can call a function like this:

To call a function with parameters:

    function_name $arg1 $arg2

And I can refer my parameters like this inside the function:

    function_name () {
       echo &quot;Parameter #1 is $1&quot;
    }

My question is, is there a better way refer to the parameters inside the function? Can I avoid the $1, $2, $3, .... thing and simply use the $arg1, $arg2, ...?

Is there a proper method for this or do I need to re-assign these parameters to some other variables inside the function? E.g.:

    function_name () {
       $ARG1=$1
       echo &quot;Parameter #1 is $ARG1&quot;
    }

Any example would be much appreciated.

How can I test if a command outputs an empty string?

Test if a command outputs an empty string

What&#39;s wrong with the following code?

    name=&#39;$filename | cut -f1 -d&#39;.&#39;&#39;

As is, I get the literal string `$filename | cut -f1 -d&#39;.&#39;`, but if I remove the quotes I don&#39;t get anything. Meanwhile, typing

    &quot;test.exe&quot; | cut -f1 -d&#39;.&#39;

in a shell gives me the output I want, `test`. I already know `$filename` has been assigned the right value. What I want to do is assign to a variable the filename without the extension.

How can I remove the extension of a filename in a shell script?

I want to remove **test.extra** from all of my file names in current directory 
 
    for filename in *.fasta;do

    done

but it complains about not founding file.echo is to be sure it list correctly.

I have this one-liner:

    get-WmiObject win32_logicaldisk -Computername remotecomputer

and the output is this:

    DeviceID     : A:
    DriveType    : 2
    ProviderName :
    FreeSpace    :
    Size         :
    VolumeName   :

    DeviceID     : C:
    DriveType    : 3

    DriveType    : 5
    ProviderName :
    FreeSpace    :
    Size         :

How do I get `Freespace` and `Size` of `DeviceID` `C:`? I need to extract just these two values with no other informations. I have tried it with `Select` cmdlet, but with no effect.

**Edit:** 
I need to extract the numerical values only and store them in variables.

I have a series of strings which are full paths to files.  I&#39;d like to save just the filename, without the file extension and the leading path.  So from this:

    c:\temp\myfile.txt

to

    myfile

I&#39;m not actually iterating through a directory, in which case something like PowerShell&#39;s `basename` property could be used, but rather I&#39;m dealing with strings alone.

I need to set a global variable from a function and am not quite sure how to do it.

    # Set variables
    $global:var1
    $global:var2
    $global:var3

    function foo ($a, $b, $c)
    {
        # Add $a and $b and set the requested global variable to equal to it
        $c = $a + $b
    }

Call the function:

    foo 1 2 $global:var3

End result:

$global:var3 is set to 3

Or if I called the function like this:

    foo 1 2 $global:var2

End result:

$global:var2 is set to 3

I hope this example makes sense. The third variable passed to the function is the name of the variable it is to set.

In Windows 7, you could go into a programs compatibility settings and check off to always run as an Administrator. Is there a similar option in Windows 8? 

I&#39;ve always disabled UAC on my machines, and did the same after my Windows 8 upgrade, or so I thought. It turns out there is no `off` option, only turning off the notifications. 

This means nothing is run as an Administrator despite being in the Administrator group. I need to keep closing and reopening my consoles\Visual Studio when I try to debug (attach to process, not &lt;kbd&gt;F5&lt;/kbd&gt;), which is very frustrating. 

It&#39;s really annoying that I need to either remember to take extra steps to open it as an Administrator or tell it to close and re-open when I go to debug for the first time.

Can you force Visual Studio to always run as an Administrator in Windows 8?

I am trying to create a new ZIP package from code with one entry and save the ZIP package to a file. I am trying to achive this with the **System.IO.Compression.ZipArchive** class. I am creating the ZIP package with the following code:

    using (MemoryStream zipStream = new MemoryStream())
    {
        using (ZipArchive zip = new ZipArchive(zipStream, ZipArchiveMode.Create))
        {
            var entry = zip.CreateEntry(&quot;test.txt&quot;);
            using (StreamWriter sw = new StreamWriter(entry.Open()))
            {
                sw.WriteLine(
                    &quot;Etiam eros nunc, hendrerit nec malesuada vitae, pretium at ligula.&quot;);
            }
Then I save the ZIP to a file either in WinRT:

            var file = await Windows.Storage.ApplicationData.Current.LocalFolder.CreateFileAsync(&quot;test.zip&quot;, CreationCollisionOption.ReplaceExisting);
            zipStream.Position = 0;
            using (Stream s = await file.OpenStreamForWriteAsync())
            {
                zipStream.CopyTo(s);
            }
Or in normal .NET 4.5:

            using (FileStream fs = new FileStream(@&quot;C:\Temp\test.zip&quot;, FileMode.Create))
            {
                zipStream.Position = 0;
                zipStream.CopyTo(fs);
            }
However, I can&#39;t open the produced files neither in Windows Explorer, WinRAR, etc. (I checked that the size of the produced file matches the Length of the zipStream, so the stream itself was saved to the file correctly.)  
Am I doing something wrong or is there a problem with the ZipArchive class?

On microsoft&#39;s site they claim that simple doctype declaration is enough. But even a document as short as this falls back to IE7 mode:

       &lt;title&gt;&lt;/title&gt;

I&#39;m still developing applications for Windows 7 of course, but I&#39;m wondering if there&#39;s a quick and easy way (read: WPF style or Windows Library) to emulate this style.  I&#39;ve done some window chrome styling in the past, but getting it to look and behave just right is really tricky.

Does anyone know if there are existing templates or libraries to add a &quot;Modern UI&quot; look and feel to my WPF applications?
