How would I tell a bash script to start over from the top?

Question

For example, in the below script startover starts back from the top:

##########################################################################
         


        

Answer 1

You could "recurse" using the following line:

exec bash "$0" "$@"

Since $0 is the path to the current script, this line starts the script without creating a new process, meaning you don't need to worry about too many restarts overflowing the process table on your machine.
