### Downloading dio

dio is now available in standard Solaris package format. Use the pkgadd command to install the package. This is the download format I would recommend as the package includes a proper man page as well. The package installs into /usr/local.

If you are having problems downloading from here (using HTTP) then you can download using FTP from Sunfreeware. Also, if would like dio for a version of Solaris that is not available here, then try sunfreeware.com

The C source code (dio.tar.gz) is available under the GPL license which embodies the spirit of invention, trust, developer credit and knowledge sharing that has allowed UNIX, in all it's various forms, to be so successful. The other main reason that I have done this is so that my code can be subjected to the full scrutiny of the UNIX community, which I think can only be a good thing.

Version 1.6 of dio is available here. It includes an option to run dio in the background. Please test and let me know if you have any problems. Only available in source form just now.

Please send me feedback if you download dio.
