Personal use license

Commercial license

Hamilton Laboratories is an independent software vendor (ISV) selling tools to professional software developers since 1988.

We are the developer and publisher of Hamilton C shell, a complete recreation of the Unix C shell and utilities for Windows with numerous enhancements. It comes with all the important utilities including mv, cp, rm, more, grep, fgrep, head, tail, diff, sed, cron, tar, etc.  There’s even a real chown, a real su (super user) and a real sudo and they all work under Windows 7, 8, 10 and 11.

World’s most powerful 64-bit shell for Windows

Hamilton C shell is the fastest, most powerful, highest quality Unix shell for Windows. Period. Since Windows began.

Completely bulletproof.  Will not crash, will not hang.  Ever.  Everything always works.  Or we fix it.  Runs on any 32 or 64-bit version of Windows ever made.  Still the only Unix shell for Windows written from scratch for Windows, not just ported.  Still the only one that’s multithreaded.  Still the only one that understands simple things like drive letters, filenames with spaces and either slash.  Still the fastest.  Still the best.

Now just $89 for personal use

Yes.  Really.  And under our All My Devices license, if it's for personal use, you can buy one license and install it on all your personal devices. Cost is no longer an excuse for suffering with poor quality tools, even if they are free and you get the source so you can fix bugs yourself.
