Powershell escaping a blank space in a variable

The following example script terminates at folder due to the space between name and number. How do I run the full string? 



$path = "C:folder1folder 2"



Invoke-Expression "$pathDB_MigrationMigrate.exe --timeout=300 -a $pathServerApplication.Core.dll -db SqlServer -conn $connectionstring"


$path is actually $PSScriptRoot on a server where I cannot simply rename the folder.



Cheers

  • Have you tried using single quotes e.g. Invoke-Expression "'$pathDB_MigrationMigrate.exe' --timeout=300..."

  • Wouldn't the single quote prevent the variable substitution?

    @Jinx - If you have double-quotes on the 'outside' and single-quotes on the 'inside', substitution still works. Give it a try: $world = 'world'; "'Hello $world'"

  • Tested and you are correct that the single quotes do allow the variable to be parsed (which is good to know - thanks) however they then prevent the parameters being accepted

    why not just use start-process instead of invoke-expression? then you wouldnt have to cramp everything into a single string
