       The file name is optional. If you do not specify a filename, it is saved in the same file that you opened. If a file name different from the one you opened is specified, the text is saved with the new name, but you continue editing the file that you opened. The next time you save it without specifying a name, it gets saved with the name of the file that you initially opened.

        While you are typing in a file, it is in-convenient to keep moving your fingers from the standard position for typing to the arrow keys. Vim, therefore, provides alternate keys for moving in the document. Note again that, you should be in the command mode, when issuing any commands to vim.

        The visual mode is a special mode that is not present in the original vi editor. It allows us to highlight text and perform actions on it. All the movement commands that have been discussed till now work in the visual mode also. The editing commands that will be discussed in the future work on the visual blocks selected, too.

        The editing commands usually take the movements as arguments. A movement is equivalent to a selection in the visual mode. The cursor is assumed to have moved over the text in between the initial and the final points of the movement. The motion or the visual block that's been highlighted can be passed as arguments to the editing commands.

       What would you do, if you want bash to execute a particular command each time you start it up? For instance, say you want the current directory to be your Desktop instead of your home folder, each time bash starts up. How would you achieve this? Bash reads and executes commands in a whole bunch of files called start-up files, when it starts up.

         When an external command is executed, a new subshell is created. Any built-in commands of bash are executed with int the same shell, and no new subshell is started. When an external command is run, the bash shell copies itself (along with it's environment) creating a subshell and the process is changed to the external command executed. The subshell is a child process of this shell.
