- You can configure your shell by editing the file~/.bashrc for instance to change the value of$ PS1 and $PAth permenatrly true or false"Add a new built-in path command that allows users to show the current pathname list, append one pathname, or remove one pathname. In your shell implementation, you may keep a data structure to deal with the pathname list. If you do not use execle() or execve() that allows you to execute with your own environment variables, you will need to add it to the “real” PATH environment variable for executables in the path to work correctly. The initial value of path within your shell shall be the pathname list contained in the PATH environment variable. Implement the path command as follows: • path (without arguments) displays the pathnames currently set. It should show pathnames separated by colons. For example, "/bin:/user/bin". • path + ./bin appends the pathname to the path variable. You may assume that only one pathname is added at a time. • path - ./bin removes the pathname to the path variable. You may assume that only one pathname is removed at a time. You may assume that there are no…Create a command quick reference card that can be used as a reference when working from the Linux command line. Then add the commands listed in this chapter to the card, as well as the most common options associated with these commands.

Ensure that you include how permissions are changed using the standard chmod commands, along with numeric representations and instructions for configuring special permissions.
- The Development team of InstantStay wants to ensure that all email data of the users are lowercase. Otherwise, their login system could have problems finding the users.
