NAME

       setcap - set file capabilities

SYNOPSIS

       setcap [-q] [-n <rootid>] [-v] {capabilities|-|-r} filename [ ... capabilitiesN fileN ]

DESCRIPTION

       In  the  absence of the -v (verify) option setcap sets the capabilities of each specified filename to the
       capabilities specified.  The optional -n <rootid> argument can be used to set the file capability for use
       only in a namespace with this rootid  owner.  The  -v  option  is  used  to  verify  that  the  specified
       capabilities  are currently associated with the file. If -v and -n are supplied, the -n <rootid> argument
       is also verified.

       The capabilities are specified in the form described in cap_from_text(3).

       The special capability string, '-', can be used to indicate that capabilities are read from the  standard
       input. In such cases, the capability set is terminated with a blank line.

       The  special  capability  string,  '-r', is used to remove a capability set from a file. Note, setting an
       empty capability set is not the same as removing it. An empty set can be used to guarantee a file is  not
       executed  with privilege inspite of the fact that the prevailing ambient+inheritable sets would otherwise
       bestow capabilities on executed binaries.

       The -q flag is used to make the program less verbose in its output.

EXIT CODE

       The setcap program will exit with a 0 exit code if successful. On failure, the exit code is 1.
