setcap - set file capabilities
setcap [-q] [-n <rootid>] [-v] {capabilities|-|-r} filename
[ ... capabilitiesN fileN ]
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.
The setcap program will exit with a 0 exit code if successful. On
failure, the exit code is 1.
