Implemented various Linux commands, as follows:
cd <path>
mkdir <path>
rm <path>
pwd
There would be an additional command, for application purpose, which is
session_clear
It will clear all the previous operations and put back the application to starting point, as if application started just now.
Problem will have a command line environment, where testing input would be as command line input.
At start, application would be at ROOT directory ‘/’, Overtime application would be provided with various commands.
Examples:
Following is in ordered way.
$ <Starting your application...>
$ pwd
PATH: /
$ cd /some/random/path/which/doesn’t/exist
ERR: INVALID PATH
$ mkdir dir1
SUCC: CREATED
$ mkdir dir1
ERR: DIRECTORY ALREADY EXISTS
$ mkdir dir2
SUCC: CREATED
$ ls
DIRS: dir1 dir2
$ cd dir1
SUCC: REACHED
$ pwd

$ cd /
SUCC: REACHED
$ rm /dir1
SUCC: DELETED
$ cd /dir1

$ mkdir /dir3

$ cd /dir2
SUCC: REACHED

$ session_clear
SUCC: CLEARED: RESET TO ROOT
