As we know:
There is no
gotostatement support in bash.
gotois useful for certain situations, especially for debugging.
So, is there any alternative mechanisms to goto in bash?
Robert Copeland gave an interesting hacking to this problem: http://bobcopeland.com/blog/2012/10/goto-in-bash/
The idea is like the self-modifying code. But the difference is to generate a piece of the script and
eval (run) it. This is not exactly the
goto statement, but achieve the very close results.
