To get hidden files and folders using PowerShell, we need to use the Get-ChildItem command with the - Hidden or -Force parameter.The difference between the two mentioned parameters is Hidden parameter only retrieves the hidden files and folders while the Force parameter retrieves all the files and folders including Hidden, read-only and normal files and folder.For example, We have one folder named Data inside folder C:\temp and we need to retrieve it.PS C:\> Get-ChildItem C:\Temp\ -Hidden Directory: C:\Temp Mode LastWriteTime Length Name ---- ------------- ------ ---- d--h- ...

In this article, we have a pagefile set on E: (System managed) and we need to remove the pagefile from E: So in the below image once we remove it, the pagefile should be “No Paging File”.To do so using PowerShell, we need to filter the pagefile on a specific drive and need to run the below code.$pagefileset = Gwmi win32_pagefilesetting | where{$_.caption -like 'E:*'} $pagefileset.Delete()You may want to reboot the server after removing pagefile.To change the above settings on the remote computer, use -ComputerName parameter in the GetWMIObject class.
To change the pagefile settings to system managed, we need to set InitialSize and MaximumSize parameters to 0. In the below example, we have E: has custom pagefile, not system managed and we need to convert it to the system managed.$pagefileset = Gwmi win32_pagefilesetting | where{$_.caption -like 'E:*'} $pagefileset.InitialSize = 0 $pagefileset.MaximumSize = 0 $pagefileset.Put() | Out-NullNow when you check the pagefile setting on E: it should be System managed.To change the settings on the remote computer use -ComputerName parameter in the Get-WmiObject method.
To change the pagefile settings, we will divide this into multiple sections. First, when Pagefile is automatically managed, we can’t modify the settings so we need to remove that box. In GUI that box can be unchecked in Virtual memory settings.Code to uncheck the above box.$pagefile = Get-WmiObject Win32_ComputerSystem -EnableAllPrivileges $pagefile.AutomaticManagedPagefile = $false $pagefile.put() | Out-NullSo once the above code is executed, other fields will be enabled. We now need to Customize the size of the pagefile in the below image by providing Initial and Maximum size using PowerShell.Here we have already the pagefile on the C: while on the ... Read More
Suppose we have a number n, and p and q. Now suppose we are standing in a line of n people. We do not know which position we are in, but we know there are at least p people in front of us and at most q people behind us. We have to find the number of possible positions we could be in.So, if the input is like n = 10, p = 3, q = 4, then the output will be 5, as there are 10 people and at least 3 are in front and at most 4 are ...

Suppose we have a lowercase alphabet string s, we have to find a string with all the vowels of s in sorted sequence followed by all consonants of s in sorted sequence.So, if the input is like "helloworld", then the output will be "eoodhlllrw", as vowels are "eo" And consonants are in sorted order "dhlllrw"To solve this, we will follow these steps −k := blank string, t := blank stringfor each character c in s, doif c is a vowel, thenk := k concatenate cotherwise, t := t concatenate creturn (k after sort and concatenate t after sorting)Let us see ...

Suppose we have a lowercase alphabet string text, and have another string called key. We have to find a new string where every letter in text[i] is moved to the right side with offset key[i]. Here the offset represented by key[i]'s position in the alphabet (A=0, B=1 etc.) If the letter overflows, it gets wrapped around the other side.So, if the input is like text = "code", key = "team", then the output will be "vsdq"To solve this, we will follow these steps −cip := a new liststart := ASCII of 'a'for each l from text and k from key, ...

Suppose we have a string s and a number n, we have to rearrange s into n rows so that s can be selected vertically (top to down, left to right).So, if the input is like s = "ilovepythonprogramming" n = 5, then the output will be ['ipnrn', 'lypag', 'otrm', 'vhom', 'eogi']To solve this, we will follow these steps −L := empty listfor i in range 0 to n - 1:insert a string by taking each nth character starting from i, and insert into Lreturn LLet us see the following implementation to get better understanding −Example Live Democlass Solution: def ...

Suppose we have a Unix path, in a list of strings, we have to find its resolved version. As we know in Unix, ".." denotes the previous directory and "." denotes stay on the current directory. Here resolving indicates evaluation of the two symbols so that we get the final directory we're currently in.So, if the input is like path = ["usr", "..", "usr", ".", "local", "etc", "foo"], then the output will be ['usr', 'local', 'etc', 'foo'], as the part represents "/usr/../usr/./local/etc" which resolves to "/usr/local/etc/foo"To solve this, we will follow these steps −s := a new listfor each element ...

Suppose we have a list of sorted numbers called nums we have to find the number of unique elements in the list.So, if the input is like nums = [3, 3, 3, 4, 5, 7, 7], then the output will be 4, as The unique numbers are [3, 4, 5, 7]To solve this, we will follow these steps −s:= a new setcnt:= 0for each i in nums, doif i is not in s, theninsert i into scnt := cnt + 1return cntLet us see the following implementation to get better understanding −Example Live Democlass Solution: def solve(self, nums): ...
