The only way to make sure that your wrapper is always called instead of the OS supplied utility is to move the OS supplied utility to a different location and install your wrapper in the location where your OS installed cut originally.

Of course, once you have installed this wrapper, your code might or might not work properly (depending on the quality of your wrapper) and no one else on your system will be able to look at the diagnostics produced by scripts that have bugs in the way they specify field and character ranges so they can identify and fix their code.

My personal opinion is that you should spend time fixing your scripts that call cut -c 0...., cut -f 0..., and lots of other possible misuses of 0 that are now correctly diagnosed as errors by the new version of cut instead of debugging code to be sure that it changes all of the appropriate 0 characters in its argument list to 1 characters and doesn't change any 0 characters that are correctly specified and do not reference a character 0 or field 0.
