Question Linux Pro's and Noobs! A Challenge, Please take a crack at this! (TIME SENSATIVE,)

Do it like this is your situation, your server, and the dir that are mentioned below, act like they are yours! im just looking for an accurate answer!
(student of O'Rielly School of Tech)

whenever you log in, your shell executes commands that it finds in your dotfiles, specifically .bash_login. In your .bash_login, add a series of commands that will first create a directory named ~/sysadmin1/my_peeps/$DATE, where $DATE is today's date in the format mmddyy. This command should succeed whether or not the directory ~/sysadmin1/my_peeps already exists. Then, it will redirect the output of the w command (which lists the currently logged in users on the system) to a file inside this newly created directory called users.$TIME, where $TIME is the current time in the format hhmmss (use 24 hour time).

In order to do this, you must use a new concept: assignment of a variable from the output of a command. For example, in order to set the variable EXAMPLEDATE using the unformatted output of the date command, you would do the following:


The characters surrounding the date command are called "backticks." They are usually located on the same key as ~. They are not single quotation marks. This is actually another kind of expansion called "Command Substitution" (you can learn more in bash's manpage).

For this project, you can use the date command to get both the date and the current time, however, you will have to consult date's manpage to find out how to change the formatting.
