Writing try catch finally in shell

Question

Is there a linux bash command like the java try catch finally? Or does the linux shell always go on?

try {
   `executeCommandWhichCanFail`
   mv output
} catch {         


        

Answer 1

mv takes two parameters, so may be you really wanted to cat the output file's contents:

echo `{ execCommand && cat output ; } || cat log`
rm -f tmp
