CASE statement
Hi,

I am writing a bash shell script. My script has a few user defined parameters. When the script runs the first thing it does is make sure that these parameters are valid. One of the parameters is called YEAR. A valid input for YEAR can be 1997-2000.

One way I have come up with to ensure that YEAR is valid is by using a case statement:

Code:
case $YEAR in 
    1997 | 1998 | 1999 | 2000 )
    echo  '- YEAR is valid'
    ;;
    *) 
    echo; echo; echo 'ERROR: YEAR is not valid (Must be 1997,1998,1999, or 2000)'
    exit 1
    ;;
esac

However, that is a simple case! In reality YEAR is valid for 1997-2008. Instead of listing each valid year in the case statement is there a way that I could just place all the valid years into an array and use that? ie:

Code:
YEAR_ARRAY=(1997 1998 1999 2000)

case $YEAR in 
    ${YEAR_ARRAY[@]} )
    echo  '- YEAR is valid'
    ;;
    *) 
    echo; echo; echo 'ERROR: YEAR is not valid (Must be 1997,1998,1999, or 2000)'
    exit 1
    ;;
esac

I have tried that and it doesn't work. Am I close? Is there a better way? Thanks a lot.

Mike

       The note field is limited to 28 characters if a track number is in use.

       You can force a tag to be v1.1 by using a specifying a non-zero track number, or force a tag to be v1.0 by specifying  a  track	number	of
