A linux terminal-based shell

Welcome to MyShell!

Introduction to the project:

I have implemented a terminal-based shell using C language.

Date: 27th September, 2018. Place: Room 224, Bakul Nivas, IIIT Hyderabad. Owner: Tanuj Garg

Features:

• All commands working on real terminal are working.
• current directory of shell is made home directory
• Some commands listed below are implemented separately
  • echo
  • ls
  • cd
  • pwd
  • clock (a clock appears)
  • fg
  • bg
  • jobs (shows status of background processes)
  • kjobs (sends a signal to a particular process)
  • overkill (kills all background processes)
  • pinfo (shows info of a particular process)
  • remindme (reminds user about something after sometime)
• Processes are made background processes when used '&'
• Pipes and redirection are handled properly

Running the program:

• Go to the working directory and run make
• Use ./shell to start shell
