rshell

rshell imitates the functionality of a terminal. rshell performs the following steps:

1. Print the command prompt userName@hostName $
2. Read in a command on one line. Commands can be separated by connectors. Connectors include &&, ||, and ;.
3. Execute the line of commands
   • If a command is followed by ;, then the next command (if any) is always executed.
   • If a command is followed by &&, then the next command is executed only if the first one succeeds (returning true).
   • If a command is followed by ||, then the next command is executed only if the first one does not succeed (returning false).
   • If a command is empty, it returns false. rshell does not output an error.
   • Anything found after the first found # is considered a comment and will be ignored.

Known Bugs

- Commands with more than 2 but less than 7 flags will not execute.
- `echo` with quotes will include quotes in output.

ls

ls implements a subset of the GNU ls command.

1. It can support the -a, -l, and -R optional flags; and the ability to pass in one or many files optional.
2. It also displays different types of files in different colors that can be combinable
   • directories are blue
   • executables are green
   • hidden files have a gray background

Known Bugs

- Files are listed in alphabetical order from left to right, then top to bottom.
- Columns are all of equal width.	
- Sometimes outputs an unnecessary endl.
