The 'num-utils' are a set of programs for dealing with numbers from the Unix command line. Much like the other Unix command line utilities like grep, awk, sort, cut, etc. these utilities work on data from both standard in and data from files.

  Gentoo
• num-utils are available on Gentoo. Just run emerge num-utils. You may have to prefix that with ACCEPT_KEYWORDS="~x86" as it is currently masked. Also, they only have version 0.3 there, so you might just want to get the tarball from here anyways.

• num-utils even work under MacOS X. They are part of the Fink distrobution of Unix utilities.

I have created a mailing list for general discussion, development, questions, tips and tricks pertaining to the num-utils. You can subscribe to the mailing list on this page.

Num-utils are currently in development and may be buggy or lacking in some respects. Anyone who is interested, is welcome to contribute in any way they feel they can. Please read the GOALS file and contact me at suso@suso.org. You should also subscribe to the mailing list if you plan to help with development.
