Synopsis

The purpose of this program is to create and execute a simple command shell, which is called rshell.

Rshell can:

• Execute most of the commands of a normal BASH shell
• Execute commands chained together using connectors
• Exit from rshell to your normal BASH shell using command exit.

As of now, rshell cannot built in BASH commands, like cd.

How to run the file

In order to run this program, you must have the Boost library installed. If you are using a Linux Operating System, run this command to install this library:

$ sudo apt-get install libboost-all-dev

After cloning repository into your local machine

Run these commands from the local repository's root directory (.../rshell/):

$ make

$ bin/rshell

To run cp or ls run these commands after make:

$bin/cp
$bin/ls

Bugs & Fixes

• Typing in more than one connector with no command (i.e, typing just ;; and hitting enter) will only give you the proper error for one connector.
• Programs do not run in the background.
• Typing in $ ls && && && ls will actually run ls twice, as opposed to just returning an error.
• Typing in a command and then a connector like && or || will actually cause the command before the connector to execute, as opposed to waiting till a second command to inputted.
• Typing in ls | echo test does not cause piping as of now.
• Typing in something like ls &&& ls will actually run the commands while still giving an error for an unexpected token, as opposed to just returning an error in a normal BASH shell.
• Quote features do not function as they are suppose to. For example, if you type in echo "hello world" you would receive hello world on a normal BASH shell. On this shell, you will see hello world.
• Formatting feature is still not up to par with the BASH shell's ls
• Some folders do not appear alphabetically when using recursive flag -R
• Bug with reading comments on chained IO redirection with piping.
• String redirection <<< not fully functional as of now. Please avoid using this function.
