问题 For 3commas I tried to generate a HMAC SHA256 signature in Powershell with the example parameters from the documentation: $secret = 'NhqPtmdSJYdKjVHjA7PZj4Mge3R5YNiP1e3UZjInClVN65XAbvqqM6A7H5fATj0j' $message = '/public/api/ver1/accounts/new?type=binance&name=binance_account&api_key=XXXXXX&secret=YYYYYY' $hmacsha = New-Object System.Security.Cryptography.HMACSHA256 $hmacsha.key = [Text.Encoding]::ASCII.GetBytes($secret) $signature = $hmacsha.ComputeHash([Text.Encoding]::ASCII.GetBytes($message

问题 My goal is to write an app that lets you quickly assign aliases to long directory paths and change to them. I wrote an app that manages them in a file in the user's appdata directory, but I can't find a way to change the directory of the shell I run the program in from my app. My goal is to have it work from git bash, cmd.exe, and powershell. I want something like this: cd /c/vsts/some-long-project-name-reports g -a reports Now I have an alias 'reports' for that directory. What I want to do

问题 In such a way that it is not in a sub shell. I need it to be able to prepare the environment...set environment variable.

问题 I know I can set a date to a variable in PowerShell using $a = Get-Date It works great, but when looking through the documentation on formatting the date, there wasn't one for MMDDYY . How do I accomplish this? 回答1: Because $a is effectively a System.DateTime. You can do: $a = Get-Date Write-Host $a.ToString('MMddyy') Full details on custom Date and Time Format Strings are in Custom Date and Time Format Strings . 回答2: You just have to get creative with the -UFormat options. To get exactly

问题 I modified what someone else had on this forum, based on a successful use of powershell Excel to pdf with no success. Any ideas on my failing in the following code? My goal is to be able to convert an entire folder of doc and docx documents to pdf without opening the native applications. Thanks in advance: # Acquire a list of DOC files in a folder $Word = New-Object -ComObject word.application $path = "c:\Users\Desktop\Test" $formats = "Microsoft.Office.Interop.Word.WdFixedFormatType" -as

问题 When using powershell and following this article running the following example throws an error. Example: 1..5 | ForEach-Object -Parallel { "Hello $_"; sleep 1; } -ThrottleLimit 5 Error: ForEach-Object : Parameter set cannot be resolved using the specified named parameters. Removing the body of the loop does not resolve the issue. It is present whenever using the -Parallel keyword. The article is from last year which makes me think the feature must still be present in powershell. Am I missing

问题 The PowerShell Strongly Encouraged Development Guidelines that cmdlets should Implement for the Middle of a Pipeline but I suspect that isn't doable for a parameter as -Last for the Select-Object. Simply because you can't determine the last entry upfront. In other words: you will need to wait for the input stream to finish until you define the last entry. To prove this, I wrote a little script: $Data = 1..5 | ForEach-Object {[pscustomobject]@{Index = "$_"}} $Data | ForEach-Object { Write-Host

问题 I am building another web server "web2", which must have the same configuration as web server "web1" So after installing some software I need to edit the "web.config" on the "web2" server to match the one in the "web1" server I am doing this from my laptop, so I copied both "web.config" files to my laptop running these commands: $w1="web1.server.local" $w2="web2.server.local" $myCred=(Get-Credential -credential "myAD\myUser") $file="C:\path\to\my\web.config" Invoke-Command -ComputerName $w1
