Nuances

• Using / multiple times is as good as using it once.

  

• Root folder is its own parent.

  • So on executing cd .. in the root, you will stay in the root folder itself.

    

ls

• Short and Long form of options

• Interpretation of directory as an argument

• Recursive listing

• Order of options on command line does not matter

• ls -l will display the files & folders in the current directly, in a list

• If we add the name of a folder after ls -l, it will display the files & folders of that folder

ls -l

ls -l level1

• Using ls -ld <folder_name> you can get output for only that folder (<name>) in long file listing format
