Seems like a weak reason. You can do already anyway. Why doesn’t MS just add those cmds or equivalent to Powershell?
Mint was good for me until they dropped Gnome,...which I need .
Or just implement BASH. A lot of folks use Cygwin for that, or at least have in the past. If you could make BASH calls from the cmd.exe, it would go a long way to making windows actually usable. Support for regular expressions is sorely needed.
