Change date to uppercase
Hello,

I'm trying to take a 3 character date and change it to uppercase, does anyone know how to do that?

Currently, all commands that I know of for changing strings/variables to uppercase change the command itself to uppercase, not the output.

Here is what I've tried:

date="date +%b"
echo $date
Aug

echo $date | tr "a-z" "A-Z"
DATE +%B
echo "$date" | tr '[a-z]' '[A-Z]'
DATE +%B

OR:
DATE=`echo $date|awk '{print toupper($0)}'`
$DATE
ksh: DATE: not found

OR:
print $date|sed 'y/[a-z]/[A-Z]'
sed: Function y/[a-z]/[A-Z] cannot be parsed.

Does anyone know how to get that date to all CAPS? (as you see above, it currently reads "Aug"...)

LEARN ABOUT OSX

setfile

SETFILE(1)						    BSD General Commands Manual 						SETFILE(1)

NAME

     /usr/bin/SetFile -- set attributes of files and directories

SYNOPSIS

     /usr/bin/SetFile [-P] [-a attributes] [-c creator] [-d date] [-m date] [-t type] file ...

DESCRIPTION

     /usr/bin/SetFile is a tool to set the file attributes on files in an HFS+ directory. 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.

     Flags:

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

     -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)

		    Z | z    Busy (allowed on folders)

     -c creator     Specifies the file's creator, where creator can be a string of four MacRoman characters, an empty string ('') designating a
		    null creator, or a binary, decimal, octal, or hexadecimal number in standard notation (e.g. 0x52486368).

     -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. The date must be in the Unix epoch, that is, between 1/1/1970 and 1/18/2038. If the
		    year is provided as a two-digit year, it is assumed to be in the 21st century and must be from 00 (2000) through 38 (2038).

     -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 can be a string of four MacRoman characters, an empty string ('') designating a null type, or a
		    binary, decimal, octal, or hexadecimal number in standard notation (e.g. 0x55455955).

RETURN VALUES

     0	      attributes set
     1	      syntax error
     2	      any other error

SEE ALSO

     GetFileInfo(1)

EXAMPLES

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

     SetFile -m "8/4/2001 16:13" myFile
