# Rshell Linux command

## Rshell functionality

Rshell is a c++ shell that is meant to replicate the same one used in UNIX. It only has basic functionalties for now but more will be added onto it later.

* A command prompt
* Recognition of various commands
* Exit functionality
* Clear functionality
* User login recognition
* Comment recognition
* Ability to change directories

## How to use cd

* To change directories, type ``cd <path>``
* Path can be changed for example ``cd home/rshell/bin/rshell``
* ``cd`` will change back to the home directory
* ``cd -`` will change to the previous directory
* the current directory will be printed after the prompt
* ``^C`` will kill the child process without exiting out of my current rshell

## Bugs

* Multiple piping does not work
* piping only works when it is provide with two arguments
* the ``<<<`` will only work by itself, will not work with any other command
* The ``1>, 1>>, 2>, 2>>`` will also only work by itself.
* The only commands that can be combined together is input and output redirection

##Limitations
* Commands has a limit of 50,000 characters
* host have a name character limit of 500 characters
* every command in the piping assignment other than input and output redirection can only be used by itself
* piping can only take in two arguments
* <<< command only works by itself
* file descriptor change to stderr only works when used by itself
* `` cat < existingInputFile | tr A-Z a-z | tee newOutputfile1 | tr a-z A-Z > newOutputFile2`` this does not work
* Make file is not attached to other functions like rm, cp, or ls. Will fix in future so make file and deal with other functionality
