Windows 10: Deleting Lines in a Text File Given Strings From Another File Using Set-String (Powershell)

Basically what's happening is that I have two files, one with a list of allowed users and another list of users that are actually on the desktop. What I'm trying to do is use a for loop to grab each name in the AllowedUsers.txt file, and use Select-String to find any names that match and delete them from the original Users.txt (with the list of users actually on the desktop). The end goal is to have a list of users that aren't allowed on the desktop left in the Users.txt file, where I can then for loop through once again and simply delete those users through command line.


Unfortunately, I have been unable to get this to work as I don't fully grasp how Select-String or for loops work, but any help writing the script would be greatly appreciated.

ordering strings alphanumerically

You don't loop it, it does via .Sort(IComparer). In my example, it would like like...
Code: List<string> list = new List<string>(); list.Add("2"); list.Add("1"); list.Add("0"); //sort it OffsetLengthPairComparer comparer = new OffsetLengthPairComparer(); list.Sort(comparer);[/quote] Obviously my comparer doesn't work for strings because it is for a custom type but, you get the idea.

 

Searching for documents with a specific text string


Assuming search indexing is working properly: note that File Explorer search should behave as you expect, if settings correct; Cortana search, on the other hand, will ONLY find indexed documents, and there are options to click on to select searching Apps, Documents, Music etc. (see Filters in Cortana's Window, top right)

Note settings that could stop this happening:



- per file



- per file type

 

Strings and Linked lists in C++

How are you telling it to display the separated string?
Could you inadvertantly be just displaying at the first string in the list and they are actaully all there?

Did you get my PM about converting to c-string and tokenizing?
