This I did not. The post was about Git Bash as a command-line shell for Windows and everything it entailed, I understood that and that's why I wrote the paragraph that followed.
I was limiting the scope of my comment to the author's familiarity on Bash versus CMD or PowerShell because I considered that the cornerstone argument of the entire post. Everything else that the author mentions is expected by default in a *sh-type shell on a Unix-like OS; there's nothing special there. People wouldn't blog about being able to use `grep`, `ls`, etc on Linux; it's just everyday business.
