okay this is really a misunderstand , I did not mean by bash the bash
programming I mean the bash source code which is writen in C
and I saw this exactly code in it "the source code of find" reduced version:
[code]
while ( --argc > 0 && (*++argv)[0] == '-' ) /*to go through arguments*/
while (c = *++argv[0]) /*to go through
strings of the agrs*/
switch (c) {
[/code]
NOTE : the source of this code is the Denis Ritchie book the C programming
language second edition
and I only tried to print this part of code to watch it's behaviour myself
