title: Convert Bash Scripts To Shell
body: <p>I have a list of scripts written in Bash, and now i need to convert them to Shell scripts. I know bash is an extended implementation of the Shell specification, and so, i'm looking for some specification of the extension implemented in Bash, namely, what's in Bash that is not part of the Shell specification, so i could go over my scripts and make the appropriate modification.
  Is there such a document?
  Alternatively, any other suggestion on how to do the conversion will be greatly appreciated.</p>
