RASH - Really a SHell is project of Mihail Stoykov for his Clinux class
It is not finished, it is not really working at all :) but there is enough code to make Nikola Vladov rip his hair off (hopefully not enough to rip mine as ewell):D
Here is what is supposed to be working;
- it should be able to read basic shell script from a file
* it is prefered to have ';' on the end of command and that there is no space before it :) and etc.
* hopefully it will skip #
* hopefully it will escape any character that have '\' before it
* hopefully it will get "as it is" any character that is in "'" or '"' braces
* it will find the executable file it should execute even if it's a symlink
* it mostprobably will execute every command with kind of file descriptor manipulation and some pthreads
* hopefully it will not segfault or use all of your memory and cpu time
- what doesn't work (hopefully for now :))
* the interactive shell is not working :) i'm sure it is in path_misc->nextChar or path_misc->nextArgument but I'm not sure;
* pretty much everything that wasn't ment to work is not working this includes:
@ I don't sent proper enveronment // could be fixed probably in an hour or two
@ I don't parse much of the things that should be parsed like pipes, filedescriptor manipulations, variable expansion and etc
@ I don't have any inner commands which will have to be done in path_misc and then execution or in just one of them :)
@ and etc and etc
It can be tested with rash.test and rash.test2 both of them should work correctly.
I'm really sorry that I couldn't atleast finish the interactive shell. I hope I will continue working in the next few days and so finish at least that or some of the other parts but I have other exams and I already stumbled on all kind of problems connected to anything from pointers through file descriptors to segfaults in an unusual places :).
