PowerShell 파일에서 문자열을 추출합니다.
To extract only strings from a file using PowerShell, you can use the Select-String cmdlet.
Here’s an example command to extract strings from a file:
Get-Content path/to/file.txt | Select-String -Pattern '\b\w+\b'이 예에서, path/to/file.txt is the path to the file you want to extract strings from. The Get-Content cmdlet reads the file and outputs its content as an array of strings. The Select-String cmdlet then searches for strings that match the regular expression pattern \b\w+\b, which matches any word character (letters, 숫자, and underscores) surrounded by word boundaries. The output of the Select-String cmdlet is a collection of MatchInfo objects that contain the matching strings.
If you want to output just the matching strings (without the MatchInfo objects), you can pipe the output to the ForEach-Object cmdlet and use the $_.Matches.Value property to extract the matching strings, like this:
Get-Content path/to/file.txt | Select-String -Pattern '\b\w+\b' | ForEach-Object { $_.Matches.Value }This will output only the matching strings from the file.
