getfileinfo

GETFILEINFO(1)						    BSD General Commands Manual 					    GETFILEINFO(1)

NAME

     /usr/bin/GetFileInfo -- get attributes of files and directories

SYNOPSIS

     /usr/bin/GetFileInfo [-P -a[<attribute-letter>] | -c | -d | -m | -t] file ...

DESCRIPTION

     /usr/bin/GetFileInfo is a tool to get the file attributes.

     With no flags, GetFileInfo retrieves all information about the file.  If exactly one option is provided, GetFileInfo retrieves and displays
     just that information; supplying more than one is an error.

     Flags:

     -P  Acts on a symlink file instead of the file the symlink resolves to.

     -a[<attribute-letter>]
		    Gets a file's attribute bits where <attribute-letter> is one of the following:

		    a	     Alias file

		    b	     Has bundle

		    c	     Custom icon (allowed on folders)

		    d	     Located on the desktop (allowed on folders)

		    e	     Extension is hidden (allowed on folders)

		    i	     Inited - Finder is aware of this file and has given it a location in a window. (allowed on folders)

		    l	     Locked

		    m	     Shared (can run multiple times)

		    n	     File has no INIT resource

		    s	     System file (name locked)

		    t	     "Stationery Pad" file

		    v	     Invisible (allowed on folders)

		    z	     Busy (allowed on folders)

		    The value of a single attribute is printed as 0 for off or false, 1 for on or true.  If no attribute letter is specified, the
		    value of all attributes is returned, with lowercase letters representing off or false, and uppercase representing on or true.

     -t 	    Gets the file type, a string of exactly four characters.  If the type is not set, these will display as an empty pair of quo-
		    tation marks.  Directories do not have types, so the type will be skipped if all information is being displayed; specifying -t
		    for a directory is an error.

     -c 	    Gets the file's creator, a string of four characters enclosed in quotation marks.  If the creator is not set, these will dis-
		    play as an empty pair of quotation marks.  Directories do not have creators, so the creator will be skipped if all information
		    is being displayed; specifying -c for a directory is an error.

     -d 	    Gets the creation date, a string of the form "mm/dd/yyyy hh:mm:ss" in 24-hour clock format.

     -m 	    Gets the modification date, a string of the form "mm/dd/yyyy hh:mm:ss" in 24-hour clock format.

RETURN VALUES

     0	      success
     1	      syntax error
     2	      any other error

SEE ALSO

     SetFile(1)

EXAMPLES

     The following command line gets and prints the creator for the "Late Breaking News" file:

     /Developer/Tools/GetFileInfo -c "Late Breaking News"

     This command line prints the modification date of "myFile":

     /Developer/Tools/GetFileInfo -m myFile
