c) ls /*/ -d

d) ls /* -d

e) ls * -d

Answer 1

The ls command in general is used to list out the contents of a particular directory in which we are correctly working in. Using -d will just list out the directory and their contents with them.

a) ls /.* - this will list out all the files which have a / as a last letter with any type of extension and it will thus actually look for sub files in the different directory present in the current directory.

b) ls .*/ - this will list out all the files in the present directory and will look into the directories as well for files.

c) this will go 2 level deep into the directory and list out all the files present their and thus not going any further.

d) this will go 1 level deep into the directory and list out all the files present their and thus not going any further.

e) work similar to the ls command.
