SETCAP(8)                   System Manager's Manual                  SETCAP(8)
NAME
       setcap - set file capabilities
SYNOPSIS
       setcap  [-q]  [-n  <rootuid>]  [-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 <rootuid> argument can be used to set the file  capability  for  use
       only in a user namespace with this root user ID 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 <rootuid> 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 capa-
       bilities are read from the standard input. In such cases, the  capabil-
       ity 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 exe-
       cuted with privilege in spite of the fact  that  the  prevailing  ambi-
       ent+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 fail-
       ure, the exit code is 1.
