Unixkit commandline tools
While I had been a pure linux user up until medical school, I’ve migrated to WinXP mainly because the media (ppt) used in medical school made it impossible to use anything but M$ and Apple software. My Athlon 700mhz desktop at the time simply was inadequate for virtualization. My current Thinkpad T42 is showing its age, and I have no plans to replace it until absolutely necessary. This left dual booting or Cygwin my only means to tweak scripts via CLI…that is, until I discovered Unixkit. It’s a little publicized compilation of unix executables for Windows that serves as a simple shell replacement without the overhead of Cygwin. Some of the files were obtained from the unixkit sourceforge site.
To install, simply extract the files into the directory of your choosing. Add the directory to your path, and execute the batch file whenever you want to fire up a command prompt, unix-style. I combine this with Launchy to execute batch file, freeing you from the mouse. Voila!
