The Perl regex syntax is also used by other languages such as JavaScript, Python, PHP and Ruby. The basic principles are still the same, though, and nearly all regular expressions used with the classic grep tool will work the same in PowerGREP. This regular expression syntax is far more advanced than the syntax used by most grep tools. PowerGREP’s regular expression engine is fully compatible with popular regex flavors such as those used by Perl, Java and the. All this makes it very easy for you to inspect the context of a match. Most files will also be shown with syntax coloring applied. All the matches in that file will also be indicated in the file viewer. You can double-click filenames, line numbers and matches in the results to open the file at the match position in PowerGREP. In addition to the filenames, line numbers and text, you will see the actual regex match highlighted in the results. But the results produced by PowerGREP are much more useful. Like the classic grep utility, PowerGREP can search through files and folders on your computer using regular expressions. The simplest PowerShell equivalent to grep is Select-String. However, it is difficult to use it in PowerShell scripts.

All in all a very useful tool for locating information stored anywhere on your computer, even (or especially) if you don’t really know where to look. Grep, a UNIX command and also a utility available for Windows and other operating systems, is used to search one or more files for a given character string or pattern and, if desired, replace the character string with another one. On the Windows Command Line (CMD), the equivalent to grep is findstr. grep will output the file names and the line numbers or the actual lines that matched the regular expression. That is because Windows executes the ps -e command from within the WSL environment, but then returns the result back to the Windows environment. It can search through files and folders (directories in UNIX) and check which lines in those files match a given regular expression. Note that the output states that the grep command is not recognized. It would then be available to you on any machine.Grep is a tool that originated from the UNIX world during the 1970’s. The default profile location for PowerShell is %USERPROFILE%\Documents\WindowsPowerShell you could technically have this live in OneDrive.

I did a quick search for 'windows explorer search markdown files' which led me to a Super User thread that said I'd have to install a Markdown Preview to do it. No dice - it found no results when I knew there were some. My initial thought, since I'm on Windows, was to use Windows File Explorer's search dialog.
