+# File Explorer: Copy(cp), Move(mv) and Remove(rm) (Concepts)
+
+* cp, mv and rm can act on either files, or directories
+  ```shell
+	  cp file1 file2
+	  mv file1 file2
+	  
+	  cp -R dir1 new/location
+	  mv dir1 new/location
+	  
+	  cp file1 file2 ... some/existing/dir
+	  mv file1 file2 ... some/existing/dir
+	  
+	  rm file1 ...
+	  rm -R dir
+	  rm -Rf dir # Danger!
+  ```
+  
+* Effectiveness of these commands greatly improved by file patterns
+  - *, ., [0-9],[ABC], {}, etc

+# File Explorer: Effective Command Line Editing (Concepts)
+
+* Moving using arrow keys is tedious
+
+* Retyping commands that contain a typo is even more tedious
+
+* *Readline* facility of the bash shell offers quicker navigation
+  - Move by a word left and right using `Ctrl`+`Left`, or `Right`
+  - Move to a beginning, or the end of the line using `Ctrl`+`A` and `Ctrl`+`E`
+  - Delete an entire word using `Alt`+`D`
+  - Paste a deleted word with `Ctrl`+`Y`
+
+* Reuse previous commands!
+  - The shell remembers what you type
+  - Move to a previous line in history using `Up` and `Down` arrows

+# File Explorer: Basics (Concepts)
+
+* While interacting with a shell, we are always in a given *working directory*
+* Data is organised into directories and files, like on other systems.
+* Location of a file in respect to the current directory is given by a (*relative*) file path
+  - some/dir/with/a/file
+
+* New commands:
+  - `pwd` : outputs the current working directory
+  - `ls [-lhd ... file1 file2 file3 ...]` : lists files 
+  - `cd path/to/existing/dir` : change current directory to a new directory
+  - `mkdir [-p] path/to/new/dir` : creates a new directory
+  - `touch file1 [file2 file3  ...]` : creates an empty file.
+  - `history` : view the list of commands executed so far

+# File Explorer: Basics
+```console
+$ pwd    # Displays the absolute path to the current dirrectory.
+$ ls     # List contents of the current directory.
+$ mkdir linux-practical-01    # Create a new directory.
+$ cd linux-practical-01    # Switch to a different directory.
