E.g. +t,a+r,g-w,+rwx,o=r\n\nOCTALMODE Mode specifed in 3 or 4 digits. If 4 digits, the first may\nbe 1 or 0 to turn the sticky bit on or off, respectively. Unlike shell command, it is not possible to specify only part of the mode\n\tE.g. 754 is same as u=rwx,g=rx,o=r\n\n\tIf none of \'augo\' is specified, \'a\' is assumed and unlike\n\tshell command, no umask is applied."

Modifier and Type	Constant Field	Value

The names are case\n\tsensitive.\n\n\tWARNING: Avoid using \'.\' to separate user name and group though\n\tLinux allows it. If user names have dots in them and you are\n\tusing local file system, you might see surprising results since\n\tshell command \'chown\' is used for local files."
