SETFATTR(1)                      File Utilities                      SETFATTR(1)

       setfattr - set extended attributes of filesystem objects

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

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

       -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

       -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.

           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

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

           Print the version of setfattr and exit.

           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.

       Add extended attribute to user namespace:

       $ setfattr -n -v bar file.txt

       To add md5sum of the file as an extended attribute:

       # setfattr -n trusted.md5sum -v d41d8cd98f00b204e00998ecf8427e file.txt
