NAME

6       runuser - run a shell with substitute user and group IDs
7

SYNOPSIS

9       runuser [OPTION]... [-] [USER [ARG]...]
10

DESCRIPTION

12       Change  the  effective user id and group id to that of USER.  Only ses‐
13       sion PAM hooks are run, and there is no password prompt.  This  command
14       is  useful  only  when run as the root user.  If run as a non-root user
15       without privilege to set user ID, the command will fail as  the  binary
16       is  not  setuid.  As runuser doesn't run auth and account PAM hooks, it
17       runs with lower overhead than su.

34              pass a single COMMAND to the shell with -c and do not  create  a
35              new session
36
37       -f, --fast
