I'm using invoke-expression in PowerShell to create an archive, but it's not working due to spaces in the exe path. These are my variables:
Set-Variable -name DIRRELEASE -value (Join-Path $env:UserProfile "\Documents\Coding\_Projects\ChickenPing\trunk\Dist\current\")
$srcPath = (Join-Path $DIRRELEASE ("myapp_1.90-src.zip"))
Set-Variable -name WinRarFilter -value "-x*\.svn -x*\.svn\* -x*\nutrition.db3"
Set-Variable -name WinRarOpts -value "-r -s -m5 -inul"
$WinRar = `"C:\Program Files\Winrar\winrar.exe`"
#Then using this to invoke:
Invoke-Expression ($WinRAR + " a " + $srcPath + " " + $WinRARFilter + " * " + $WinRAROpts)
When I run the script I get this error:
The term 'a' is not recognized as the name of a cmdlet, function,
script file, or operable program. Check the spelling of the name, or
if a path was included, verify that the path is correct and try
again. At line:1 char:3
+ a <<<< C:\Users\Echilon\Documents\Coding_Projects\MyApp\trunk\Dist\c

-s - m5 -inul
+ CategoryInfo : ObjectNotFound: (a:String) [], CommandNotFoundEx ception

I just can't find the right combination of quotes and plusses.
You could make this a lot easier to work with by using the call operator &.
& $WinRAR a $srcPath "-x*\.svn" "-x*\.svn\*" "-x*\nutrition.db3" * -r -s -m5 -inul

Im trying to run:

pause
but i fails with error:

and if I run command directly in powershell it works! what am I doing wrong?
Change inside double quotes to single:
powershell.exe -Command " Rename-Item 'HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{%ethguidclean%}' -NewName '11111111-1111-1111-1111-111111111111' "
Can someone please explain the following behaviour to me?

If I had a penny for every minute I've wasted on PowerShell's insistance that backticks, quotes and other meta-characters are just right, I would be the richest man on Earth! Somebody please save me from this madness!
And BTW, what I'm actually trying to do is recurse through a bunch of folders and delete everything that isn't a video file, like so...
Remove-Item -Path $filePath -Recurse -Exclude '*.avi','*.mkv','*.mp4'
...which doesn't work for (presumably) the same reason: not being able to pass a variable to the -Path parameter. And if someone is feeling really generous, they could also help me with this. MTIA! :D
Use -LiteralPath instead of -Path because some of the special characters where interpreted with -Path.
Remove-Item -LiteralPath
Special characters are just so much fun in PS right?
-LiteralPath works exactly like Patrick explained, but they don't allow for wildcards; because they're literal.
Have you tried using single quotes ' instead of double quotes ". This allows you to escape special characters, while still evaluating wildcards. Try the commands below:
New-Item -Path 'C:\Users\username\PSScripts\bracket`[\te$t.txt'
Get-Item -Path 'C:\Users\username\PSScripts\bracket`[\*'
Also, if it helps, I use VSCode for most scripting and, if you use tab completion, it will format this properly for you.
I hope that helps!
The solution to my overall problem ended up being this line of my batch script:
powershell -Command "Get-ChildItem -Recurse -LiteralPath %filePath% | Where-Object Extension -match '^(?!(\.avi|\.mkv|\.mp4)$)' | Remove-Item"
The regex was the hardest to get right, since I haven't used negative lookaheads before, but after ~2 hours of total time spent on this one line of code, it finally works!

My Script contains
$letterArray = "a","b","c","d"
foreach ($letter in $letterArray)

Write-Host $letter
}
Move the script to another(deeper) folder and try again? You can also try
& c:\test.ps1
I am trying to run the below against multilpe servers using Powershell 3.0 but for some reason I am getting back that the path does not exist...even though it does?
Any ideas?
CODE:

In single quotes ' the variable are not expanded but treated as literal as $computer1, the $ for the $admin share must be escaped with a backtick `
The path that can't be found only has one \ on the front of it, a UNC share must begin with two \'s. I can see from your code it looks like you are prefixing the two \'s but it doesn't look like it's being carried over.
I would use double quotes instead of single quotes as already pointed out, if you do that then you should not need to escape the $ character either.
Assuming a file called file.txt exists in the C:\temp folder on the local machine.
This fails:
$computer1 = "localhost"
Test-Path '\\$computer1\c$\temp\file.txt'
This works:
$computer1 = "localhost"
Test-Path "\\$computer1\c$\Temp\file.txt"
I have a script that requires 3 mandatory input parameters that will be used to run the backup command for tdpsql.

Any help will be really appreciated.
You might try Invoke-Expression $cmd instead of & $cmd.
Yes better use Invoke-Expression, but if you still want to use & you can do it in this way.
$cmd = "C:\Windows\System32\notepad.exe"
$params = "C:\temp\file.txt"
& $cmd $params
Using a var for program file ans a var for parameters.
Instead of running a batch command you'd better try Powershell cmdlets as follow
import-module "C:\Program Files\Tivoli\Flashcopymanager\fmmodulemmc.dll"
import-module "C:\Program Files\Tivoli\Flashcopymanager\fmmoduleSQL.dll"
$startTime = get-date
Backup-DpSqlComponent -Name AdventureWorks2012 -BackupDestination TSM -BackupMethod Legacy -Full
$endTime = get-date
$activity = Get-FcmMmcActivity -StartTime $startTime -EndTime $endTime
$activity
