# US - User {Switcher,Shell}
|
|
|
|
|
|
|
|
|
|
Opens a shell as a different user without needing to authenticate as that user.
|
|
|
|
|
This is similar to the behavior of `su` but it allows to execute privileged
|
|
|
|
|
and/or commands as any other user without needing their password.

|
It doesn't use PAM, instead relies on shadow files and the passwd database
|
|
|
|
|
to check if the given password is correct. Support for different methods of
|
|
|
|
|
authentication is planned.

## Installing
|
|
|
|
|
|
|
|
|
|
To install use `make install` and to uninstall use `make uninstall`, all
|
|
|
|
|
other documentation is provided as man pages, `man us` will give general
|
|
|
|
|
information about the utility and how to use it and `man us.conf` contains
|
|
|
|
|
info about the config file format.
|
|
|
|
|
|
|
|
|
|
## Supported platforms
|
|
|
|
|
|
|
|
|
|
All platforms that store the encrypted password in `/etc/passwd` should be
|
|
|
|
|
supported, which to this day are none. Linux is supported through `shadow(3)`
|
|
|
|
|
and OpenBSD through its API. Support for more systems is planned.
|
|
|
|
|
This program is libc-agnostic as (apart from authentication) it is POSIX
|
|
|
|
|
compliant code.
