SuS

Execute the command as another user using su.

What's that?

This is a su-based program for executing commands on behalf of other users. It was created to simplify the use of su -c as a lightweight replacement for sudo. But unlike sudo, it asks for the target user's password instead of the current user's, and does it every time.

How to use?

For example, use:

sus whoami

The root user is used by default (the DEFAULT_USER value in sus.c).

To specify a user, use the -u argument:

sus -u admin whoami

The argument can be specified only at the beginning, otherwise it will be interpreted as part of the command to be executed.

Installation

Any su implementation that has the -c argument must be installed on the system.

Clone the repository:

git clone https://github.com/wioun/sus

Go to the repository directory:

cd sus

Compile with any convenient C compiler:

cc ./sus.c -o ./sus

Install the binary (as root):

install -m 755 ./sus /usr/bin

If you're using bash-completion, install sus_completion.bash to /etc/bash_completion.d/ (as root):

install -m 644 ./sus_completion.bash /etc/bash_completion.d/sus_completion.bash
