This is a basic, lightweight implementation of a UNIX shell.

To compile and run the shell, first make sure to create ./bin and ./obj directories and then run:

>> make clean
>> make
>> ./bin/yashShell

In addition to typical shell commands, features include:

• When the user presses the “enter” key twice in a row, the shell displays the list of files in the current working directory.
• >> touch hello.c; touch hello2.c; rm -rf hello.c: Reads multiple commands separated by a semicolon character.
• >> history : Prints the previous HIST_LEN number of commands.
• >> time : Prints the current date and time in an human readable form.
• >> cd : Changes the directory.
• >> ps -ef | grep root: Piping.
• >> exit : Exits the yashShell.
