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.
