select-string

问题 I am complete new in writting powershell scripts. So far I was using plain batch for my purpose as this is the requirement by my company. Inside this batch I am using nested foor loops to make a comparison of two .txt files, in detail I wantdo do the following: File 1 contains lots of strings. Each string is in one seperate line with a preceded number and semicolon like so: 658;RMS File 2 is some long text. The aim is to count the amount of occurences of each string from File 1 in File 2, e.g

问题 I am trying to parse through a text file with regex finding percentages as strings and replacing the findings with the percentage multiplied by a user supplied integer. If the user inputs 400, then the code should return "120 x 8, 180 x 6, etc" Tried doing a replace but it replaces all findings with the same string. $body = "30% x 8, 45% x 6, 55% x 4, 60% x 2, 65% x 1, 70% x 1, 75% x 1, 80% x 1, 72.5% x 4, 70% x 4, 67.5% x 4, 65% x 4" $regex1 = "(\d+(\.\d+)?%)" $regex2 = "(\d+(\.\d+)?)"

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

问题 Thanks to @mklement0 for the help with getting this far with answer given in Powershell search directory for code files with text matching input a txt file. The below Powershell works well for finding the occurrences of a long list of database field names in a source code folder. $inputFile = 'C:\DataColumnsNames.txt' $outputFile = 'C:\DataColumnsUsages.txt' Get-ChildItem C:\ProjectFolder -Filter *.cs -Recurse -Force -ea SilentlyContinue | Select-String -Pattern (Get-Content $inputFile) |

问题 I am trying to extract each line starting with "%%" in all files in a folder and then copy those lines to a separate text file. Currently using this code in PowerShell code, but I am not getting any results. $files = Get-ChildItem "folder" -Filter *.txt foreach ($file in $files) { if ($_ -like "*%%*") { Set-Content "Output.txt" } } 回答1: I think that mklement0's suggestion to use Select-String is the way to go. Adding to his answer, you can pipe the output of Get-ChildItem into the Select

问题 I need return a line preceeding a match on a multi-line string variable. It seems when using a string variable for the input Select-String considers the entire string as having matched. As such the Context properties are "outside" either end of the string and are null. Consider the below example: $teststring = @" line1 line2 line3 line4 line5 "@ Write-Host "Line Count:" ($teststring | Measure-Object -Line).Lines #verify PowerShell does regard input as a multi-line string (it does) Select
