differences in linux and unix shell

hi all,
can any one plz tell me that what is the difference between linux shell scripting and unix shell scripting.
is there any difference at all?? if yes that what are the differences and how could it be combatted
thanks in advance

The differences are usually not between Linux and Unix, but the type of shell you are going to use. On Linux you usually use bash, on different Unix'es it can be ksh or others. So it is a question of which shell you are going to use. It could also be the case, that some type of shell might not be available on the derivate you are going to use.
