Use bat to start Powershell script
powershell .\test.ps1 arg1 'arg2 with space' arg3
or
powershell .\test.ps1 arg1 """arg2 with space""" arg3
I think you should try to avoid using double quotes as cmd already uses them too and therefore it's a little hard to predict what exactly PowerShell will get. Remember that this gets passed through two shells and therefore two layers of escaping/quoting.
PowerShell itself doesn't make much of a distinction between single and double quotes. At least in this context the difference is irrelevant.

I have a batch file test.bat to start a powershell script:
@pushd "C:\myscripts" powershell .\test.ps1 arg1 "arg2 with space" arg3 @popd
The script test.ps1 (located at C:\myscripts) is a very simple one like:
# just print out the arguments Write-Output ("args count: {0}" -f $args.length) $args
Then I tried to start test.bat. I should get three arguments passed to ps1 but I got the following result:
args count: 5 arg1 arg2 with space arg3
What I expected in the script, args[0] should arg1 and args[1] should be "arg2 with space" and args3[2] be arg3. I cannot understand why the script actually gets 5 arguments.
How can I pass parameters from cmd or batch to powershell as what I expected? Like this:
args count: 3 arg1 arg2 with space arg3
