RECOMMENDED USING LINUX In order to run the program, follow these steps:

1. git clone http://github.com/ifuka001/rshell.git
2. cd rshell
3. make
4. bin/rshell for rshell. bin/ls for ls bin/cp for cp

Rshell should be now opened instead of your bash and it will be able to execute most of the commands except few. For example the cd command will not work yet.

updated(11/11/2014): added ls feature and cp feature. these will work like the actualy ls and cp. (ls only has -R -l and -a flags compatible.)

updated(11/19/2014): added i/o redirection and pipe in rshell.

updated(12/3/2014): added cd command and added signal interrupt so Ctrl+C does not close rshell.

• rshell can do most of the commands BASH can excluding few for the moment.
• rshell supports the usage of arguments, such as, ; && ||
• Just like the actual BASH itself, the program will find your login name and host name and will display it along with the $ prompt.
• To terminate the program, you must enter exit in the command line.
• You may use # to make comments in your program.

11/11/2014:

• Added ls and cp. ls has 3 flags -l -a and -R and they can be used in many ways. ( -l, -Ra, -lRa, etc)
• Added cp. if an argument was passed through after the Source and the Destination (it can be anything), it will output 3 different methods and how long each one took to output it to the file.
• Note that the cp cannot take flags in the beginning or between the source file and the destination file.

11/19/2014:

• Added input/output redirection and piping in rshell program. It is able to do simple input "<" and output ">" redirection ( and append ">>")

12/03/2014:

• Added the cd command so user can change directory inside rshell.
• Also added signal interrupt so Ctrl+C does not close rshell instead close the process running at that time.

• rshell cannot use the command 'cd' at this time because it is not implemented.
• rshell does not allow you to combine all the arguments. For example, ls -a; pwd || echo "hi" && mkdir temp ls && pwd || echo "goodbye"
• In rshell the commands ls and/or with flags will work for now, but in the future we will add in the code to make it work better.
• rshell does not support the usage of TAB key to find other commands with a similar letters typed in. It will read it as a user input and just print out an error message.
• It will also not allow you to echo a line of string into a file like BASH does. Instead it will just print out what you wrote after the echo command (excluding the comments made after a #)
• ls if the file name length is longer than 20characters, it might cause issue when outputting the file.
• ls recommended bash size is 80width to show the output neat.
• cp can only take flag parameter at the end of destination or it will not run properly.
• For example: cp only runs by inputting bin/cp "sourcefile" destinationfile" or bin/cp "sourcefile" destinationfile" "flag"
• rshell piping does not support multiple i/o redirection within the pipe itself (for example, cat< Makefile| cat < Makefile >> new1)
• rshell also does not allow multiple input and output redirections. it does not also allow output and append to be on same line of command
• rshell only supports up to 100 pipes. If you call more, it will cause errors.
• rshell will not support cd ~ because ~ is a bash unique character.
• rshell will not print out a new prompt like regular bash when Ctrl+C is clicked to interrupt program. (But it will after you use a command.)
