sui

Execute a Sui subcommand

$ sui [subcommand]

$ sui move [subcommand]

$ sui client [subcommand]

$ sui start

$ cargo install --locked --git https://github.com/MystenLabs/sui.git --branch testnet sui

As sui is not a standard command in modern Linux, a direct synopsis for sui does not exist. If referring to sudo, a concise synopsis is:
sudo [options] command [arguments...]
or for listing permissions:
sudo [-lLAnvV]

-u user
    Run the command as the specified user instead of the default target user (usually root).

-i
    Run the shell specified by the target user's password database entry as a login shell. This simulates a full login session.

-s
    Run the shell specified by the SHELL environment variable of the calling user. Often used for running a sub-shell with elevated privileges.

-l
    List the commands allowed for the current user on the current host. Can be combined with -U to check another user's permissions.

-k
    Revoke the user's cached credentials. The next sudo command will require a password.

-b
    Run the command in the background. The user's password may be required before the command is run.

-H
    Set the HOME environment variable to the target user's home directory instead of leaving it as the invoking user's HOME.

command
    The command to be executed with elevated or specified user privileges.

arguments...
    Any arguments that are passed to the command being executed.

The command sui is not a standard or widely recognized utility in modern Linux distributions. Its appearance in contexts often points to a typographical error, most commonly for sudo. sudo (superuser do) is a crucial command that allows a permitted user to execute a command as the superuser or another user, as specified by the system's security policy. It provides a more granular and secure method for privilege elevation compared to directly using su or logging in as root, by enforcing accountability and logging of privileged operations. While sui has been historically linked to obscure "Start Up Interface" utilities in very old Unix systems (like System V Release 4), this usage is obsolete and irrelevant to contemporary Linux. For the purpose of this analysis, the information provided below pertains to sudo, which is the likely intended command when sui is encountered.

The command sui is not a standard Linux utility. Attempting to use it will likely result in a "command not found" error. All information provided in this analysis regarding functionality, synopsis, and parameters refers to the `sudo` command, which is often mistakenly typed as `sui`. Proper configuration of `sudo` through the `/etc/sudoers` file (using `visudo`) is critical for security and system stability; incorrect entries can lead to serious security vulnerabilities or prevent legitimate users from performing necessary tasks.

The behavior of `sudo` is controlled by the `/etc/sudoers` file. This file specifies which users or groups can execute which commands, from which terminals, and under what conditions (e.g., without a password). It is strongly recommended to edit this file using the `visudo` command, which provides syntax checking and prevents common errors that could lock out privileged users.

`sudo` enhances security by allowing administrators to grant specific users only the necessary privileges for specific tasks, rather than giving them full `root` access. It also logs all commands executed via `sudo`, providing an audit trail of privileged operations, which is crucial for accountability and security monitoring.

As sui is not a standard command, it has no direct development history within modern Linux. The `sudo` command, which `sui` often refers to due to typo, was originally written by Robert Coggeshall and Cliff Spencer in 1980 at the Department of Computer Science at SUNY Buffalo. It was significantly rewritten by Todd C. Miller starting in 1993, evolving into the ubiquitous tool it is today. Its development has focused on providing granular control over privileged access, extensive logging, and robust security features, making it an indispensable part of Unix-like operating systems for secure administration.
