NAME¶

setfattr - set extended attributes of filesystem objects

SYNOPSIS¶

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

DESCRIPTION¶

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

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.
