NEWROLE(1)								NSA								NEWROLE(1)

newrole - run a shell with a new SELinux role
newrole [-r|--role] ROLE [-t|--type] TYPE [-l|--level] LEVEL [-- [ARGS]...]
Run a new shell in a new context. The new context is derived from the old context in which newrole is originally executed. If the -r or --role option is specified, then the new context will have the role specified by ROLE. If the -t or --type option is specified, then the new context will have the type (domain) specified by TYPE. If a role is specified, but no type is specified, the default type is derived from the specified role. If the -l or --level option is specified, then the new context will have the sensitivity level specified by LEVEL. If LEVEL is a range, the new context will have the sensitivity level and clearance specified by that range. Additional arguments ARGS may be provided after a -- option, in which case they are supplied to the new shell. In particular, an argument of -- -c will cause the next argument to be treated as a command by most command interpreters. If a command argument is specified to newrole and the command name is found in /etc/selinux/newrole_pam.conf, then the pam service name listed in that file for the command will be used rather than the normal newrole pam configuration. This allows for per-command pam config- uration when invoked via newrole, e.g. to skip the interactive re-authentication phase. The new shell will be the shell specified in the user's entry in the /etc/passwd file. The -V or --version shows the current version of newrole
