Using Ubuntu OS$,$ write and implement ONE $(1)$ bash shell script. Manually copy the $/$etc$/$passwd file into the same folder as your script and use the root account to execute the script. The script needs to execute on the $$passwd$$ file that have been copied to the folder, and NOT on the original $/$etc$/$passwd file. That means some commands cannot be used in your script, such as id$,$ getent, pwck$,$ useradd, etc. The script will be executed with no arguments, and it can be executed in any folder. However, you can assume that your script will not be executed in the $/$etc folder.

The script will prompt the user to enter a filename of a file in the current folder $($the file format is the same as $/$etc$/$passwd file$).$

o It will check whether the file exists in the current folder, if the file does not exist, it will prompt the user to enter the filename again.

o It will keep asking the user to enter the filename again until the user enter a filename of a file that exist in the current folder.

o If the file exists in the current folder, it will proceed to check the content of the file and display ONLY the following information on the screen:

$$ number of user accounts $($you are to assume that the user account is having a shell of $/$bin$/$bash or $/$bin$/$sh$)$

$$ username of the user accounts

$$ the smallest user id $($UID$)$ among all the user accounts

o The script will then display the following information according to the file size.

$$ If the file size is less than $2000$ bytes, change the permission of the file to owner can read, write and execute, group can read and write, and others don$$t have permission.

$$ If the file size is equal or more than $2000$ bytes, display the number of days elapsed since $1$ January $2024.$
