Any seasoned admin will agree that command line is the faster as compare to GUI under Windows and UNIX.
As a part of my job some time I am forced to work in a Windows only environment and I do miss my bash shell very badly 🙁
Recently Microsoft announced Windows PowerShell. This new shell and scripting language helps IT Professionals achieve greater productivity. Using a new admin-focused scripting language, more than 130 standard command line tools, and consistent syntax and utilities, Windows PowerShell allows IT Professionals to more easily control system administration and accelerate automation 🙂
