I have to start an application with my own user rights, but the group must be different. So, instead of:
$ ps -eo "user,group,args" | grep qbittorrent
morfik morfik /usr/bin/qbittorrent
it should be for example:
$ ps -eo "user,group,args" | grep qbittorrent
morfik p2p /usr/bin/qbittorrent
It also has to be done without asking about password. Is there a way to achieve this?
Use sg.
For example, the following command will invoke sleep for group group-name
sg group-name -c 'sleep 100'
From the man page:
NAME
sg - execute command as different group ID
SYNOPSIS
sg [-] [group [-c ] command]
DESCRIPTION
The sg command works similar to newgrp but accepts a command. The
command will be executed with the /bin/sh shell...
sg ask for group password
sudo have option -g that do same by user password.
it require mention group in sudoers
I changed /etc/sudoers by
%wheel All=(ALL) ALL
to
%wheel All=(ALL:ALL) ALL
Sometimes it more convenient
Safe way to edit sudoers is:
sudo sudoedit /etc/sudoers
To avoid the password prompt with sg add yourself as a member of the group
sudo gpasswd -M morfik p2p
You may also need to remove the password and restrict access to only members
sudo gpasswd -r p2p
sudo gpasswd -R p2p
man gpasswd will give you more detail
