Echo date variable from data input to a script
Hi, I'm trying to make a script which you type the year, select the month and day and then create the date in the format 2010-12-7.
Code:
#!/bin/bash

dia () {
echo " Seleccione el dia:"
select file in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Salir
do
case $file in
"1") d=1 ; fecha ;;
"2") d=2 ; fecha ;;
"3") d=3 ; fecha ;;
"4") d=4 ; fecha ;;
"5") d=5 ; fecha ;;
"6") d=6 ; fecha ;;
"7") d=7 ; fecha ;;

"27") d=27 ; fecha ;;
"28") d=28 ; fecha ;;
"29") d=29 ; fecha ;;
"30") d=30 ; fecha ;;
"31") d=31 ; fecha ;;
"Salir") exit 1;;
 *)
    echo "ERROR: Seleccione correctamente... "
    dia;;
esac
done
}

mes () {
echo " Seleccione el mes:"
select file in enero febrero marzo abril mayo junio julio agosto septiembre octubre noviembre diciembre Salir
do
case $file in
"enero") m=1 ; dia ;;
"febrero") m=2 ; dia ;;
"marzo") m=3 ; dia  ;;
"abril") m=4 ; dia  ;;
"mayo") m=5 ; dia  ;;
"junio") m=6 ; dia  ;;
"julio") m=7 ; dia  ;;
"agosto") m=8 ; dia  ;;
"septiembre") m=9 ; dia  ;;
"octubre") m=10 ; dia  ;;
"noviembre") m=11 ; dia  ;;
"diciembre") m=12 ; dia  ;;
"Salir") exit 1;;
 *)
    echo "ERROR: Seleccione correctamente... "
    mes;;
esac
done
}

anno () {
echo " Seleccione la anno, insertando las dos ultimas cifras:"
read yshort

if [[ $( echo $yshort | sed 's/^[-+0-9][0-9]*//' | wc -c ) -ne 1 ]]; then echo "ERROR: Introduzca correctamente dos caracteres numericos." && exit 1; fi

if [[ $( expr length $yshort) -ne 2 ]] ; then echo "ERROR: Introduzca SOLO dos caracteres" && exit 1 ;fi
Y=20$yshort
}

fecha () {
fecha=`echo " $Y-$m-$d"`
echo $fecha
exit 0
}

main () {

anno
mes
dia

}

main

The problem? Simple, I want to select the day regarding the month, I mean, to print 30 days if you selected the month of 30 days and so on.

Any help on how to change my script?
Thanks in advance.

DIA(1)								  [FIXME: manual]							    DIA(1)

NAME

       dia - a diagram drawing program

SYNOPSIS

       dia [-c] [--credits] [-e OUTPUT] [--export=OUTPUT] [-L LAYER,LAYER,...] [--show-layers=LAYER,LAYER,...] [-h] [--help] [-n] [--nosplash]
	   [-s WxH] [--size=WxH] [-t FORMAT] [--filter=FORMAT] [-v] [--version] [file ...]

DESCRIPTION

       Dia is used to create diagrams. Dia has a number of basic tools, like lines and boxes but can also dynamically load sheets. A sheet is a
       collection of tools that are used in a certain type of diagram.

       Most diagram objects in Dia have connection points. Lines can be connected to these connection points and this way graph structures can be
       formed. When objects are moved or resized the connections will follow the objects.

       Diagrams drawn in Dia can be exported as PostScript.

OPTIONS

       Dia accepts the following options:

       -c --credits
	   Display credits list and exit.

       -e OUTPUT --export=OUTPUT
	   Export loaded file to OUTPUT and exit.

       -h --help
	   Display a list of all commandline options.

       -n --nosplash
	   Do not show the splash screen.

       -s WxH --size=WxH
	   Export loaded file in decimal given width and/or height. It is allowed to only select width or height. E.g.	--size=520x exports an
	   image that is 520 pixels wide, while --size=x900 exports an image of 900 pixels height.

	       Note
	       This option is currently only implemented for the PNG export filter.

       -L LAYER,LAYER,... --show-layers=LAYER,LAYER,...
	   Only include specified layers when exporting. Layers can be specified either as a layer name, the layer number or a numeric range X-Y
	   of layers. --show-layers=background,2-5 shows the layer named background and layers 2-5, --show-layers=2- shows layers 2 and up.

       -t FORMAT --filter=FORMAT
	   Export loaded file in FORMAT and exit. Format are described below.

       -v --version
	   Display dia version and exit.

EXPORT FORMATS

       The following export formats are supported by dia.

       o   cgm (Computer Graphics Metafile, ISO 8632)

       o   dia (Native dia diagram)

       o   dxf (Drawing Interchange File)

       o   eps or eps-builtin or eps-pango (Encapsulated PostScript)

	   The format specifications eps and eps-pango both use the font renderer of the Pango library, while eps-builtin uses a dia specific font
	   renderer. If you have problems with Pango rendering, e.g. Unicode, try eps-builtin instead.

       o   fig (XFig format)

       o   mp (TeX MetaPost macros)

       o   plt or hpgl (HP Graphics Language)

       o   png (Portable Network Graphics)

       o   shape (Dia Shape File)

       o   svg (Scalable Vector Graphics)

       o   pstricks-tex (TeX PSTricks macros)

       o   pgf-tex (TeX PGF/tikz macros)

       o   wpg (WordPerfect Graphics)

       o   wmf (Windows MetaFile)

FILES

       dia creates a directory .dia in the user's home, which contains different files to store user preferences. To reset dia to it's default
       behaviour, just remove the respective file:

       o   defaults.dia: contains default values for elements (XML format).

       o   diarc: keeps dia preferences (ASCII).

       o   history: keeps the list of last edited diagrams (ASCII).

       o   menurc: contains an automated accelerator map dump (Lisp).

       o   persistence: contains GUI information, e.g. open windows (XML).

       o   pluginrc: the list of loaded plugins (XML).
