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 you try and build sudo, *please* 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,
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 file. For a
summary of major changes to the current stable release, see the web
If you are upgrading from an earlier version of Sudo, please see
the UPGRADE file in the doc directory.
For a history of sudo please see the HISTORY file in the doc directory.
You can find a list of contributors to sudo in the doc/CONTRIBUTORS file.
To build sudo from the source distribution you need a POSIX-compliant
operating system (any modern version of BSD, Linux or Unix should
work), an ANSI/ISO C compiler that supports variadic marcos (a C99
feature) and the ar, make and ranlib utilities.
If you wish to modify the parser then you will need flex version
2.5.2 or later and either bison or byacc (sudo comes with a pre-flex'd
tokenizer and pre-yacc'd grammar parser). You'll also have to
uncomment a few lines from the Makefile or run configure with the
--with-devel option. You can get flex from http://flex.sourceforge.net/.
You can get GNU bison from ftp://ftp.gnu.org/pub/gnu/bison/ or any

To subscribe to a list, visit its url (as 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 http://www.sudo.ws/ that contains
an overview of sudo, documentation, downloads, information about
beta versions and other useful info.
If you have found what you believe to be a bug, you can file a bug
report in the sudo bug database, on the web at http://www.sudo.ws/bugs/.
Please read over the `TROUBLESHOOTING' file in the doc directory *before*
submitting a bug report. When reporting bugs, please be sure to include
the version of sudo you are using as well as the platform you are running
