Set attributes of HFS+ files. It attempts to be similar to the setfile command in MPW. It can apply rules to more than one file with the options applying to all files listed.
Syntax SetFile [-a attributes] [-c creator] [-d date] [-m date] [-t type] file ... Key -a attributes Sets the file attributes bits where attributes is a string of case sensitive letters. Each letter corresponds to a file attribute: an uppercase letter indicates that the attribute bit is set (1), a lowercase letter indicates that it is not (0). Note: attributes not specified remain unchanged. A | a Alias file B | b Has bundle C | c Custom icon (allowed on folders) D | d Located on the desktop (allowed on folders) E | e Extension is hidden (allowed on folders) I | i Inited - Finder is aware of this file and has given it a location in a window. (allowed on folders) L | l Locked M | m Shared (can run multiple times) N | n File has no INIT resource S | s System file (name locked) T | t "Stationery Pad" file V | v Invisible (allowed on folders) -c creator Specifies the file's creator, where creator is a string of exactly four characters. -d date Sets the creation date, where date is a string of the form: "mm/dd/[yy]yy [hh:mm:[:ss] [AM | PM]]" Notes: Enclose the string in quotation marks if it contains spaces. Period '.' represents the current date and time. [yy]yy < 100 assumes 21th century, e.g.20yy. -m date Sets the modification date where date is a string of the form in -d above. (mm/dd/[yy]yy [hh:mm:[:ss] [AM | PM]]) -t type Sets the file type, where type is a string of exactly four characters. SetFile is part of /Developer/Tools/
