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
