установить возможности файла (set file capabilities)
Имя (Name)
setcap - set file capabilities
Синопсис (Synopsis)
setcap [-q] [-n <rootuid>] [-v] {capabilities|-|-r} filename [
... capabilitiesN fileN ]
Описание (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
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 in spite 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.
Статус выхода (Exit)
The setcap program will exit with a 0 exit code if successful. On
failure, the exit code is 1.
