Bash stands for "Bourne again shell". There are a number of different shells that can run Unix commands, and on the Mac Bash is the one used by Terminal. If you want to make the window bigger, click on the bottom right corner and drag it outwards.
Master the command line: Copying and moving files on the Mac
The quickest way to get to know Terminal and understand how it works is to start using it. To run a command, you just type it at the cursor and hit Return to execute. Every command is made up of three elements: the command itself, an argument which tells the command what resource it should operate on, and an option that modifies the output. You should now see a list of all the files in your Documents folder — ls is the command for listing files. To see a list of all the commands available in Terminal, hold down the Escape key and then press y when you see a question asking if you want to see all the possibilities.
To see more commands, press Return. Unix has its own built-in manual. So, to learn more about a command type man [name of command] , where "command" is the name of the command you want find out more about. Firstly, every character matters, including spaces.
If you want to re-run a command, tap the up arrow key until you reach it, then press Return. Commands are always executed in the current location. Use the cd command, followed by a directory path, like in Step 1 above, to specify the folder where you want a command to run. There is another way to specify a location: go to the Finder, navigate to the file or folder you want and drag it onto the Terminal window, with the cursor at the point where you would have typed the path. Now save it to the TerminalTest folder in your Documents folder.

Now type ls and you should see "TerminalTestFile" listed. That will change the name of the file to "TerminalTestFile2". You can, of course, use any name you like. The mv command means "move" and you can also use it to move files from one directory to another. Terminal can be used for all sorts of different tasks. Some of them can be performed in the Finder, but are quicker in Terminal.
Here are a few examples. In a Terminal window, type d itto [folder 1] [folder 1] where "folder 1" is the folder that hosts the files and "folder 2" is the folder you want to move them to. To see the files being copied in the Terminal window, type -v after the command. The command used to delete, or remove, files in Terminal is rm. So, for example, if you wanted to remove a file in your Documents folder named "oldfile. Thanks in advance!
You need the -J option with xargs. Excellent solution, just what I was after!

In my search for other solutions prior to posting this questions, several had the head command with -5 and not -n5. Wasn't sure if that was acceptable shorthand, or syntax error. I guess i'm still not sure.
As you mentioned to me in a comment to my answer, your solution does not handle filenames with spaces, it there a way to achieve it modifying your command slightly? With BSD head both are the same. Your solution will definitely be slower but it will handle filenames with spaces in them.
My solution will not in its current form. Would not mind you showing me or even editing my answer, thanks. Featured on Meta. Congratulations to our 29 oldest beta sites - They're now no longer beta!
