I found a instance that I need to find the filename from the absolute path that was not a local path. In this case I found I can use "Split" resolve the filename.

##Example:

$strName = "D:\Microsoft SQL Server\MSSQL.1\MSSQL\ABC_DBA.mdf"

$filename = $strName.split("\")[(($strName.split("\").count)-1)]

##To break this down and explain...(but note only 2 lines are needed to get the outcome)

$strName = "D:\Microsoft SQL Server\MSSQL.1\MSSQL\ABC_DBA.mdf"

##get the count of splits (This returns "5")

$strName.split("\").count

##this would be the manual way to return the exact part of the array that gives us the filename

$strName.split("\")[4]

##We will now insert the count(5) and subtract 1 in place of the 4 (because the array begins with 0, not 1)

$strName.split("\")[(($strName.split("\").count)-1)]

##lastly i assign the above line into a variable called filename

$filename = $strName.split("\")[(($strName.split("\").count)-1)]

You can eliminate the current dir from the path by calling split-path -parent twice.

Example:

$ScriptDir = Split-Path -Parent $MyInvocation.MyCommand.Path

$ScriptParentDir = Split-Path -Parent $ScriptDir

$MyInvocation.MyCommand.Path returns the path to the script file.

If you just need the parent directory you can shorten it to the following:

$ScriptParentDir = Split-Path -Parent ( Split-Path -Parent $MyInvocation.MyCommand.Path )

Nice article for a newbie like me.

Although when I tried this using a UNC path their is a problem. $pwd doesnt just return the current UNC path but instead returns

Microsoft.PowerShell.Core\FileSystem::\\ServerName\ShareName

However the FullName property returns just

\\ServerName\ShareName\FileName

As such the $pwd.path.length is incorrect when executing

$_.FullName.SubString($pwd.path.length)

As this also will count the length of

Microsoft.PowerShell.Core\FileSystem::

The next command will give you all available aliases:
