Failing in batch powershell












4














I have a powershell command that runs fine.



$(Get-Item c:1.txt).lastwritetime=$(Get-Date "01/22/2002 11:11 am")


I'd like to use it multiple time. Using a batch file. Before the batch file I used this:



Set-ExecutionPolicy Unrestricted


The batch contains commands like this one:



powershell -Command "$(Get-Item c:1.txt).lastwritetime=$(Get-Date "01/22/2003 11:11 am")"


The batch file fails, I got two error messages per command:



Get-Date : A positional parameter cannot be found that accepts argument '11:11'.

At line:1 char:49

+ $(Get-Item c:1.txt).lastwritetime=$(Get-Date <<<<  01/22/2003 11:11 am)

    + CategoryInfo          : InvalidArgument: (:) [Get-Date], ParameterBindingException

    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.GetDateCommand



Exception setting "LastWriteTime": "Cannot convert null to type "System.DateTime"."

At line:1 char:25

+ $(Get-Item c:1.txt). <<<< lastwritetime=$(Get-Date 01/22/2003 11:11 am)

    + CategoryInfo          : InvalidOperation: (:) , RuntimeException

    + FullyQualifiedErrorId : PropertyAssignmentException


Unfortunately I don't know what is wrong. Can some help me out?

You need to either escape the inner double quotes with a backslash (because cmd would see the date time unquoted)



powershell -Command "(Get-Item .1.txt).lastwritetime=(Get-Date "01/22/2003 11:11 am")"


or exchange the inner double with single quotes (as DavidPostill suggested).



powershell -Command "(Get-Item .1.txt).lastwritetime=(Get-Date '01/22/2003 11:11 am')"


Also the $ are only neccessary when forcing the expression inside a string.

Probability when a professor distributes a quiz and homework assignment to a class of n students.

Image
0 0 $begingroup$ Need help with this problem. Suppose our lazy professor collects a quiz and a homework assignment from a class of n students one day, then distributes both the quizzes and the homework assignments back to the class in a random fashion for grading. Each student receives one quiz and one homework assignment to grade. (a) What is the probability that every student receives someone else's quiz to grade, and someone else's homework to grade? (b) What is the probability that no student receives both their own quiz and their own homework assignment to grade? In this case, some students may receive their own quiz, and others may receive their own homework assignment. (c) Compute the limiting probability as n approaches infinity in each case. ...
