Command Line Calculator: Windows DOS prompt calculator

From the website:

This is an easy to use calculator that can be run from any Windows DOS prompt. The beauty of this command line calculator is that not only can you do simple calculations while doing other chores, but you have a ticker tape where you can scroll back up and see previous results. Also, running from the command line makes passing the results to other programs or into a file very easy.

Command Line Calculator supports most common mathematical expressions such as sin, cos, tan, log, exp, random number generation, etc.

Clink: Add bash command line editing to Windows cmd.exe

I have always hated the Windows command terminal. This little extension solves some of the headaches.

From the Clink page:

Clink enhances your productivity in Microsoft Windows’ “cmd.exe”.
If you’re familiar with Bash then you will be familiar with the changes that Clink brings to “cmd.exe” (it uses the same ‘Readline’ library that
Bash uses). It is a small utility to enhance “cmd.exe”, adding more powerful command line completion, editing, and history.

  • The same line editing as Bash (from GNU’s Readline library).
  • History persistence between sessions.
  • Scriptable completion with Lua.
  • New keyboard shortcuts;
    • Paste from clipboard (Ctrl-V).
    • Incremental history search (Ctrl-R/Ctrl-S).
    • Powerful completion (TAB).
    • Undo (Ctrl-Z).
    • Automatic “cd ..” (Ctrl-Alt-U).
    • Environment variable expansion (Ctrl-Alt-E).
  • Coloured and scriptable prompt.
  • Context sensitive completion;
    • Executables (and aliases).
    • Directory commands.
    • Environment variables
    • Thirdparty tools; Git, Mercurial, SVN, Go, and P4.
  • Auto-answering of the “Terminate batch job?” prompt.
