visudo is a command-line utility that allows editing of the
/etc/sudoers file in a safe fashion. It opens
/etc/sudoers, using the
vi editor's interface by default (although this can be changed by setting the shell's
EDITOR environment variable to a different text editor), prevents multiple simultaneous edits with locks, performs sanity checks and checks for parse errors.
runas command provides similar functionality in Microsoft Windows but cannot pass current directories, environment variables or long command lines to the child. And while it supports running the child as another user, it does not support simple elevation. A true su and sudo for Windows that can pass all of that state information and start the child either elevated or as another user (or both) is included with Hamilton C shell.
There exist several frontends to
sudo for use in a GUI environment, notably
gksudo, and user interfaces not directly built on
sudo but providing similar temporary privilege elevation for administrative purposes, such as User Account Control in Microsoft Windows. and Mac OS X Authorization Services.

Famous quotes containing the words tools and, programs, tools and/or similar:
“At the utmost, the active-minded young man should ask of his teacher only mastery of his tools. The young man himself, the subject of education, is a certain form of energy; the object to be gained is economy of his force; the training is partly the clearing away of obstacles, partly the direct application of effort. Once acquired, the tools and models may be thrown away.”
—Henry Brooks Adams (18381918)
“We attempt to remember our collective American childhood, the way it was, but what we often remember is a combination of real past, pieces reshaped by bitterness and love, and, of course, the video pastthe portrayals of family life on such television programs as Leave it to Beaver and Father Knows Best and all the rest.”
—Richard Louv (20th century)
“In child rearing it would unquestionably be easier if a child were to do something because we say so. The authoritarian method does expedite things, but it does not produce independent functioning. If a child has not mastered the underlying principles of human interactions and merely conforms out of coercion or conditioning, he has no tools to use, no resources to apply in the next situation that confronts him.”
—Elaine Heffner (20th century)
“Custom, then, is the great guide of human life. It is that principle alone, which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past.”
—David Hume (17111776)
