Hi... this all very well and I would love it to work but being the illiterate thing that I am I am having problems.
If I go to finder, type in Terminal, open Terminal, all I get is a box that welcomes me and cannot be changed in any way - what am I doing wrong - how do I open a terminal window - what is a terminal??? (this is the level of understanding I am at!)
Can anyone help??
Terminal is an application that allows you to interact with the underlying OS via command line utilities rather than through the graphical user interface (GUI).
You should have a prompt like the following:
Last login: Thu Nov 15 23:24:04 on console
LittleMac:~ xxx$
typing unix commands and hitting return/enter will execute the commands.
Some common unix commands are as follows (
http://www.indiana.edu/~uitspubs/b017/):
cd - change directory
ls - list files in directory
mkdir - make directory
rmdir - remove directory
mv - move files
rm - remove files (i.e. delete)
You can google unix commands for more information. While they may seem confusing at first, they can be extremely efficient at performing many different types of tasks over using a GUI.
Admiraldennis suggested that you change directory into Desktop (cd Desktop), which is actually a directory in the underlying unix file system. Make a new directory JPEGs (mkdir JPEGs), which will appear as a new folder in the finder on the desktop. And then move all of the files ending in .jpg and .jpeg into the directory JPEGs (mv *.jpg *.jpeg JPEGs/).
At that point your desktop would no longer be cluttered with image files. They should all be located in a new directory/folder called JPEGs.
I would avoid deleting files with rm from the terminal application as they are permanently deleted.
Hope this helps.
P.S. "sudo rm -rf" is extremely dangerous! sudo executes commands as superuser status (i.e. root or admin). rm is remove files. rm -rf is remove all files recursively without prompting regardless of file permissions or status. You could very easily delete every file on your hard drive leaving your computer useless. Fortunately, sudo prompts you for a password before it executes the command, but still do not follow previous suggestion unless you are extremely confident in what you are doing.
