Is there a similar utility to grep available from the Windows Command Prompt, or is there a third party tool for it?
I realize its an old question but I came across this post seeking an answer. And I have found one so adding it here for the collective internet memory
Powershell: Select-String Module: Microsoft.PowerShell.Utility
https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/select-string
and an informative blog post with advanced examnples: "How to “grep” in PowerShell" https://antjanus.com/blog/web-development-tutorials/how-to-grep-in-powershell/
A simple example from that blog post: cat package.json | Select-String -Pattern webpack ls ./src/components/ | Select-String -Pattern View
C:> cat post.md | Select-String -Pattern "^\w*:"
