3 point if/else statement

bioinformatics_guy · 03-27-2009, 05:22 AM

In bash, the only if/else structure I can find is

if [ ] ; then

else

fi

What if I have three things I want to check, such as:

if [ ] ; then

elsif [ ] ; then

else

fi

Does this structure exist or do I just need to do some large nested if/else loop

    pattern1 )
        statements ;;
    pattern2 )
        statements ;;
    ...
