Unix commands compatible with Windows?
I'm planning to write a PHP script that makes use of various Unix commands such as `rcs`. I know that Windows has DOS built in which can run some commands such as `cd`, `ls`, etc. I was just wondering what commands are supported under Windows and would be compatible with both systems. Is there a list of supported commands under Windows? I know the vast majority of Unix commands are not compatible with Windows, but I just want to check.
Thanks. |

This doesn't answer your question completely, but maybe it's a starting place for you. XP actually has two command processors, one for backward compatibility with 16-bit systems. This is the 32-bit set. You will find that 'ls' is not common between the two systems. Better not to jump to any conclusions.

Windows doesnt have a "ls" command. Instead it has a "dir" command. There are very few that have the same name on both. Google search came up with this seemingly decent comparison chart:

Thanks, I didn't realize the two were so different.

If you don't pursue compatibility, the customers and regulatory bodies will eventually shoot you. If you do, you get sued for stealing "look and feel". There's also the ol' "not invented here" syndrome.

Whether this will be useful to you depends on the context, but if you want to add some Unix utilities (like ls, grep, and several other stalwarts) to a Win32 system, you can; do a google for "unix utilities win32" and you should find some useful results. Of course, if you're not in a position to install extra software on the Windows machines in question, this will not help you.
If you are forced to use DOS commands and rework your systems to parse their output, be warned that the name is not the only difference between the likes of DIR and ls; pipes have never really worked well in the DOS shell and there are all kinds of other weird issues. Remember to check out the command-line arguments to the DOS commands; the output from DIR /B is a lot more like ls, which could help you with adaptation of any existing code. Personally I'd just stick with Unix-like systems. It seems you have very little experience of Win32 systems, and I strongly suspect you're not going to enjoy the culture shock. It's hard to move from a platform where things can be expected to work in a predictable fashion and behave as described in the documentation to a flaky toaster like Windows. My employer operates a Win32 only environment, so I've had to move from Unix development to Win32 (in VB of all languages) and it's quite a come down, stepping off the solid bedrock of C, PHP, Perl, BSD Sockets and the Bourne Shell into the shifting sands land of Win32 and .NET. Aside from the fact that my employer will not pay me to develop on Linux, I can honestly say I see no advantage in this gaudy proprietary closed-source antistandard dungpile of an operating environment.

Here is a link to the the win32 GPL'ed unxutils
http://unxutils.sourceforge.net/ They work great for me, but to get the zip + the update zip. The first zip has path info, the update does not. If you need more unix on win32 you may want to check out cygwin. Mark |

A fuller alternative to unxutils is Windows Services for UNIX but it may be overkill.
