How to configure Terminal to be “Putty-like” when it comes to copy-paste with mouse

Assuming you are using bash: If you activate emacs shortcuts with set -o emacs you can also use Emacs to edit the command line:

• Type Ctrl-XCtrl-E at the prompt to start Emacs
• Paste and edit your clipboard content into the Emacs buffer
• Use Ctrl-XCtrl-C to exit Emacs and automatically run the command(s).

So, does it matter if the file is the same file?

ie: Let say there is a picture google.png

and you want it to copied into the same dir 4 times.

as an in that directory you would have google.png google 2.png google 3.png google 4.png?

If thats what you want:

for i in {1..4}
  do
     cp google.png "google$i.png"
  done

But if you want the "images" files to be different, and they are going to be gibrish files, but 10m in size exactly

you wanna do something like

for i in {1..5}
   do
      dd if=/dev/random of="yourfilename$i.test" bs=12428800 count=1
   done

This will make four files that are 10m in size filled with bunch of random characters.

Comment and let me know what you really want and I can go back and redo this.

It would help if you posted your script that fails so I can see what youre trying to do.

EDIT:

Changed the in device from /dev/zero to /dev/random to generate random file content.
