7. VAX DCL TO UNIX SHELL SCRIPT CONVERSIONThis chapter will describe the steps necessary to convert DCL command files into Shell scripts. It is not a one to one conversion and many features found in one operating system are not found in the other. This requires you to write shell scripts that emulate features of the other. This is especially true of VAX and UNIX. The best way to accomplish this is to know exactly what it is that the command file does in VMS and then write the equivalent function in a shell script. There are few features that are the similar and those will be examined. There is really no "best" way to approach this subject. VMS and UNIX are both unique operating systems. Much of the material covered in this course up to this point will be used in the conversion process. We will start with a list of standard UNIX tools and their VMS equivalents. This will give a you a flavor of the kinds of tools each operating system has to offer.
