Имя (Name)

setfattr - set extended attributes of filesystem objects

---

Синопсис (Synopsis)

setfattr [-h] -n name [-v value] pathname... setfattr [-h] -x name pathname... setfattr [-h] --restore=file

---

Описание (Description)

The setfattr command associates a new value with an extended attribute name for each specified file.

---

Параметры (Options)

-n name, --name=name
           Specifies the name of the extended attribute to set.

       -v value, --value=value
           Specifies the new value of the extended attribute. There are
           three methods available for encoding the value.  If the given
           string is enclosed in double quotes, the inner string is
           treated as text. In that case, backslashes and double quotes
           have special meanings and need to be escaped by a preceding
           backslash. Any control characters can be encoded as a
           backslash followed by three digits as its ASCII code in
           octal. If the given string begins with 0x or 0X, it expresses
           a hexadecimal number. If the given string begins with 0s or
           0S, base64 encoding is expected.  Also see the --encoding
           option of getfattr(1).

       -x name, --remove=name
           Remove the named extended attribute entirely.

       -h, --no-dereference
           Do not follow symlinks.  If pathname is a symbolic link, it
           is not followed, but is instead itself the inode being
           modified.

       --restore=file
           Restores extended attributes from file.  The file must be in
           the format generated by the getfattr command with the --dump
           option.  If a dash (-) is given as the file name, setfattr
           reads from standard input.

       --raw
           Do not decode the attribute value. Can be used to set values
           obtained with getfattr --only-values.

       --version
           Print the version of setfattr and exit.

       --help
           Print help explaining the command line options.

       --  End of command line options.  All remaining parameters are
           interpreted as file names, even if they start with a dash
           character.

Примеры (Examples)
