This is a bit pointless:

1. You can only find out the name of the command, it doesn't tell you what the
actual command does, or if it behaves the way you expect (for example, the
script could be picking up a custom grep that doesn't support the options you
need). Or it could be a function in a sourced file.

2. In some cases, you can only find the command to execute *after* running the
script.

So, no, there's no solution. The most you can do is some static analysis to
find the command names that are not dynamic and to source the files that are
available at this step.
