The sudo philosophy

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.

Where to find sudo

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

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).

What's new

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
