#Overview
This is a simple shell which will get the login name and host and output them together with a dollar sign at the end.
Following this will be an input by the user which will be processed and acted on appropriately.
#How to Install
All you need to do is to just:
1.) clone the repository and type in make,
2.) type bin/rshell to run the program,
#How to Use
You may type and run several types of executable commands and their parameters. They may also be connected by a connector. It will work with any number of commands and parameters and connectors may be placed anywhere in between commands. Some examples include:
* ls -a
* pwd ; ls -a
* ls -a; pwd&&exit
* ls && pwd ;ls -a ||ps
This shell can also run another instance of itself, which can be seen if you use ps.
When connectors are used, the commands are read from left to right and only for the next command.
For example:
ls || pwd ; ps
The ls will run and return true. Since the connector is an ||, pwd will not run,
but the next command, ps, will.
###Whitespace
Inserting whitespace anywhere around your commands will still compile and will only fail if there is a bad input.
###Exit
An input of exit will take you out of the terminal. This will work with any
parameters that come after it. However, if it is passed in as a parameter, it will
not work.
For any bad inputs, the commands will not run and you will be prompted to try again.
###Comments
Comments may be used by inserting a # before your comment. It may be placed anywhere
in the input, but any characters after it will be ignored.
ls -a #;pwd
ls -a will run but since pwd is after the # sign, it will be ignored.
###Special Cases
A valid input followed by either ;, |, or & without any input after that will
still be correct. For example:
ls -a ;
will still work.
