... Feel free to add your own example above to help other Linux-lovers !


Run COMMAND with completely-specified CONTEXT, or with current or transitioned security context modified by one or more of LEVEL, ROLE, TYPE, and USER.

If none of -c, -t, -u, -r, or -l, is specified, the first argument is used as the complete context. Any additional arguments after COMMAND are interpreted as arguments to the command.

Note that only carefully-chosen contexts are likely to successfully run.

Run a program in a different security context. With neither CONTEXT nor COMMAND, print the current security context.

Complete security context

-c, --compute

compute process transition context before modifying

-t, --type=TYPE

type (for same role as parent)

-u, --user=USER

user identity

-r, --role=ROLE


-l, --range=RANGE
