A simple attempt at a shell implemented in the C language. For now the commands are: - help: this one. - quit: quits the shell. - exit: same as above. - environ: display environmental variables for the process. - echo <text>: echos the text back to stdout. - ls [dir]: lists files in a directory, if dir is not specified the current directory is listed. - dir [dir]: same as ls. - clr/clear: clears the screen and puts it in the top left corner, this does not work for all terminals.
