My Shell or Mini Shell

This is a shell implimentation written initially by Vijaykumar B. It was send to mailing list of Embedded Linux Meetup group chennai. Following are the features planned to add on top of this code.

• I/O redirection command to redirect command output to a file.
• Pipeline implimentation.
• Setting environment and that can be used by a command.

Compiling the code

$ cd glowing-c/trunk
$ make mshell

Runing mshell

• Run the compiled mshell

$ ./mshell
/home/user/project/glowing-c/trunk$ h
c: Change Directory
f: Execute Command
x: Exit
i: I/O redirection
h: Help
/home/user/project/glowing-c/trunk$ f
cmd: ps

5734 pts/4    00:00:00 mshell
5736 pts/4    00:00:00 ps
/home/user/project/glowing-c/trunk$

Testing I/O redirection with mshell

/home/user/project/glowing-c/trunk$ i
cmd: ls
filename: new.txt
/home/user/project/glowing-c/trunk$ f
cmd: cat new.txt
mshell
mshell.c
new.txt
singley.c
test.c

String copy with out using strcpy

Instead of using standard string function, copying string from one buffer to other in a one line logic.

$ cd glowing-c/trunk
$ make string-copy
$ ./string-copy
Enter the string: welcome
input buffer welcome

Destination Buffer welcome
