Getting Started with PowerShell and Rege

1. PowerShell bietet mehrere Sprach­kon­strukte, die eine Verwendung von RegEx zu­lassen. Bei der syntaktischen Umsetzung orien­tierte sich Microsoft - anders als etwa bei Word - weitgehend an Perl, so dass für die meisten RegEx-erfahrenen Anwender der Lernaufwand gering bleibt
2. Regular expression tester with syntax highlighting, explanation, cheat sheet for PHP/PCRE, Python, GO, JavaScript, Java. Features a regex quiz & library
3. On lines three and four, we're testing to see if each variable matches the pattern '^\d{6}$' which is regex speak for start of the line, any digit, and six of them, end of the line. The first one will be true because it's six digits, and the second one will be false. You could also use something like '^\d{4,6}$' to validate that the int is between four and six digits long
4. Comme de nombreux langages, PowerShell est compatible avec les expressions régulières (RegEx) et cela va permettre de vérifier si une chaîne est conforme à un format que l'on définit grâce à une expression régulière. Très puissantes, les expressions régulières ne sont pas forcément faciles à prendre en main..

Speed up information retrieval with these expressions. By Boe Prox ; 06/02/2016; Whether you are parsing logs or validating input, using regular expressions is a great way to accomplish both of these things. The problem is: regular expressions can be hard and that will only grow as more complex regular expressions. A regular expression is a special sequence of characters that helps you match or find other strings or sets of strings, using a specialized syntax held in a pattern. They can be used to search, edit, or manipulate text and data. Here is the table listing down all the regular expression metacharacter syntax available in PowerShell ∠Another way to use regex in PowerShell is within a switch statement. In the below example I'm using regular expression to validate user names in Active Directory.
