RUNCON(1) User Commands RUNCON(1) NAME runcon - run command with specified security context SYNOPSIS runcon CONTEXT COMMAND [args] runcon [ -c ] [-u USER] [-r ROLE] [-t TYPE] [-l RANGE] COMMAND [args] DESCRIPTION Run COMMAND with completely-specified CONTEXT, or with current or tran‐ sitioned 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 SELinux security context. With neither CONTEXT nor COMMAND, print the current security context. Mandatory arguments to long options are mandatory for short options too. 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 role -l, --range=RANGE levelrange --help display this help and exit --version output version information and exit Exit status: 125 if the runcon command itself fails 126 if COMMAND is found but cannot be invoked 127 if COMMAND cannot be found - the exit status of COMMAND otherwise AUTHOR Written by Russell Coker.
