The last command executed in the function or script determines the exit status. Within a script, an. command may be used to deliver an nnn exit status to the shell (nnn must be an integer in the 0 - 255 range). When a script ends with an exit that has no parameter, the exit status of the script is the exit status of the last command executed in the script (previous to the exit).
