问题 I want to decode the password from a System.Security.SecureString to a readable password. $password = convertto-securestring "TestPassword" -asplaintext -force $credentials = New-Object System.Net.NetworkCredential("TestUsername", $password, "TestDomain") This code part works fine, I can use the $credentials object.

问题 I'm trying to run a program from PowerShell, wait for the exit, then get access to the ExitCode, but I am not having much luck.

问题 DIR or GCI is slow in Powershell, but fast in CMD. Is there any way to speed this up? In CMD.exe, after a sub-second delay, this responds as fast as the CMD window can keep up dir \\remote-server.domain.com\share\folder\file*.* In Powershell (v2), after a 40+ second delay, this responds with a noticable slowness (maybe 3-4 lines per second) gci \\remote-server.domain.com\share\folder\file*.* I'm trying to scan logs on a remote server, so maybe there's a faster approach. get-childitem \\$s

问题 I am trying to replicate the functionality of the cat command in Unix. I would like to avoid solutions where I explicitly read both files into variables, concatenate the variables together, and then write out the concatenated variable. 回答1: You can simply use cat example1.txt, example2.txt | sc examples.txt . You can surely concatenate more than two files with this style, too. Plus, if the files are named similarly, you can use: cat example*.txt | sc allexamples.txt The cat is an alias for

问题 I would like to monkeypatch a PowerShell 2.0 environment where the upgrade to 3.0 is not possible at this time.

问题 I have a requirement to exclude files based on year, country name and last modified date from that particular year and rest files from that particular year and the country moved to an archive folder for an example SS_MM_Master_finland_2018.xlsx last modified date 27/06/2018 19:00.
