PowerShell file paths

I run the command (Get-Location), and it returns the current location of a file.

Example: c:\folder1\folder2\folder3\XXX\folder4\folder5

Firstly, from the above, I want to get the value of XXX and let it equal to a variable. How can I do this?

Secondly, I want to get the value of c:\folder1\folder2\folder3\XXX\folder4\ an开发者_如何学God let it equal to a variable. How can I do this?

I have used the placeholders folder1, folder2, etc. for illustration. These are dynamic.

To answer your second question first: to get the parent to the full path, use Split-Path:

$var = Split-Path -parent "c:\folder1\folder2\folder3\XXX\folder4\folder5"

For your other question, this function will split all the elements of your path and return them into an array:

function Split-Paths($pth)
{
    while($pth)
    {
        Split-Path -leaf $pth
        $pth = Split-Path -parent $pth
    }
}

You can then grab the 5th element like this:

$xxx = (Split-Paths "c:\folder1\folder2\folder3\XXX\folder4\folder5")[-5]

Note that the function returns the elements in "reverse" order, so you use a negative index to index from the end of the array.

Some of these answers are pretty close, but everyone is forgetting their shell-fu.

$FirstAnswer = (Get-Item ..\..).Name
$SecondAnswer = (Get-Item ..).FullName

To get the path into a variable, you can do something like this:

$a = (Get-Location).Path

Then, if you want to set the value of the 'XXX' part of your path to a variable, you can use the split() function:

$x = $a.split('\')[4]

You could do this with a regular expression:

PS> $path = 'c:\folder1\folder2\folder3\XXX\folder4\folder5'
PS> $path -match 'c:\\([^\\]+)\\([^\\]+)\\([^\\]+)\\([^\\]+)'
True
PS> $matches

Name                           Value
----                           -----
4                              XXX
3                              folder3
2                              folder2
1                              folder1
0                              c:\folder1\folder2\folder3\XXX

You can use regular expressions:

$rawtext = "If it interests you, my e-mail address is tobias@powershell.com."

# Simple pattern recognition:
$rawtext -match "your regular expression"
  *True*

# Reading data matching the pattern from raw text:
$matches

$matches returns the result.
