SETFATTR(1)							  File Utilities						       SETFATTR(1)

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. See also 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. --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. AUTHOR

NAME
getfattr - get extended attributes of filesystem objects SYNOPSIS
getfattr [-hRLP] -n name [-e en] pathname... getfattr [-hRLP] -d [-e en] [-m pattern] pathname... DESCRIPTION
For each file, getfattr displays the file name, and the set of extended attribute names (and optionally values) which are associated with that file. The output format of getfattr -d is as follows: 1: # file: somedir/ 2: user.name0="value0" 3: user.name1="value1" 4: user.name2="value2" 5: ... Line 1 identifies the file name for which the following lines are being reported. The remaining lines (lines 2 to 4 above) show the name and value pairs associated with the specified file. OPTIONS -n name, --name=name Dump the value of the named extended attribute extended attribute. -d, --dump Dump the values of all extended attributes associated with pathname. -e en, --encoding=en Encode values after retrieving them. Valid values of en are "text", "hex", and "base64". Values encoded as text strings are enclosed in double quotes ("), while strings encoded as hexidecimal and base64 are prefixed with 0x and 0s, respectively. -h, --no-dereference Do not follow symlinks. If pathname is a symbolic link, the symbolic link itself is examined, rather than the file the link refers to. -m pattern, --match=pattern Only include attributes with names matching the regular expression pattern. The default value for pattern is "^user\.", -m which includes all the attributes in the user namespace. Refer to attr(5) for a more detailed discussion on namespaces. --absolute-names Do not strip leading slash characters ('/'). The default behaviour is to strip leading slash characters. --only-values Dump out the extended attribute value(s) only. -R, --recursive List the attributes of all files and directories recursively. -L, --logical Logical walk, follow symbolic links. The default behaviour is to follow symbolic link arguments, and to skip symbolic links encoun- tered in subdirectories. -P, --physical Physical walk, skip all symbolic links. This also skips symbolic link arguments. --version Print the version of getfattr 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. AUTHOR
