ls command to list out the file names,directory(along which file is present), file details(size,date time) at one stretch

Welcome to LQ!

If you read the manual with man ls or look here
https://www.tecmint.com/15-basic-ls-...ples-in-linux/
you can see lots of options with ls. For example, try
ls -l
and then compare
ls -lgGh
Then try
ls -lgGhR

You may find that ll is the same asls -l. That's an example of an alias. You can make your own with a command like
alias ll="ls -lgGhR"
saved in the file .bashrc in your home directory.
