Sudo is a program designed to allow a sysadmin to give limited root privileges to users and log root activity. The basic philosophy is to give as few privileges as possible but still allow people to get their work done.

Before building sudo, make sure you have the current version. The latest sudo may always be gotten via anonymous ftp from ftp.sudo.ws in the directory /pub/sudo/ or from the sudo web site, https://www.sudo.ws/

The distribution is sudo-M.m.tar.gz where M is the major version number and m is the minor version number. Beta versions of sudo may also be available. If you join the sudo-workers mailing list you will get the beta announcements (see the Mailing lists section below).

See the NEWS file for a list of major changes in this release. For a complete list of changes, see the ChangeLog. For a summary of major changes to the current stable release, see https://www.sudo.ws/releases/stable/.

If you are upgrading from an earlier version of Sudo, read docs/UPGRADE.md for information on changes in behavior that may affect you.

For a history of sudo see docs/HISTORY.md. You can find a list of contributors to sudo in docs/CONTRIBUTORS.md.

Read the installation guide, INSTALL.md, before trying to build sudo. Pay special attention to the "OS dependent notes" section.

See docs/CONTRIBUTING.md for information on how you can help contribute to sudo.

Sudo is distributed under an ISC-style license. Refer to LICENSE.md for details.

To subscribe to a list, visit its url (listed above) and enter your email address to subscribe. Digest versions are available but these are fairly low traffic lists so the digest versions are not a significant win.

Mailing list archives are also available. See the mailing list web sites for the appropriate links.

There is a sudo web page at https://www.sudo.ws/ that contains documentation, downloads, a bug tracker, the source repo, the sudo blog, information about beta versions and other useful info.

If you believe you have found a bug, you can either file a bug report in the sudo bug database, https://bugzilla.sudo.ws/, or open a GitHub issue, whichever you find easier. If you would prefer to use email, messages may be sent to the sudo-workers@sudo.ws mailing list (public) or to sudo@sudo.ws (private).

For sudo's security policy and how to report security issues, see docs/SECURITY.md.

Please check docs/TROUBLESHOOTING.md before submitting a bug report. When reporting bugs, be sure to include the version of sudo you are using, the operating system and/or distro that is affected, and, if possible, step-by-step instructions to reproduce the problem.
