Re: Shell-Creation.

[omicron@xxxxxxx]

hi madhu
	i've a very simple, crude, barebones program that does a sort of
create a shell. i remember i used it to escape the command logging by bash
and also the display of commands by w.it's old and uses gets() which u r
not supposed to.
--------start of program------
#include<stdio.h>
void main()
{
	do {
		printf("command:>");
		gets(str);
		if (strcmp(str,"exit")==0)
			exit(0);
		system(str);
	  } while 1;
}
--------end------------
	me thinks it works( it worked long ago) , but i dont know if it
has mistakes. *BUT YOU CANNOT USE ANY INTERNAL COMMANDS !!!!!! *. means
cd also wont work ! hope this gives u the idea ;-)

cheers
cheedu
