Question cp, mv destination name change


Hello all, probably a really quick and easy anwser to this, but didn't really know what to search for or how to word it. So my question is ..

When I use the cp or mv command to copy/move files is there a way for me to have the destination file assume the same name of the source file, however add an additional suffix. For example

Code:
#>cp /tmp/testfileReallyReallyLongNameDoNotWantToHaveToType.log /tmp/logs/
this will copy test.log into the /tmp/logs/ directory, resulting in the file create /tmp/logs/test/log

now what if I wanted this...

Code:
#>cp /tmp/testfileReallyReallyLongNameDoNotWantToHaveToType.log /tmp/logs/testfileReallyReallyLongNameDoNotWantToHaveToType.log.bak
Do I have to type the destination file out manually everytime? or is there a quick way for the cp or mv command to assume the source file name and add the .bak

you could read about "-S"/"--suffix" switch on "man cp" or "man mv"

EDIT: nevermind, that switch it's for "backup mode", when you will overwrite files, the command just renames the old files using the specified "--suffix" - Not what you're asking for

How about
Code:
x=testfileReallyReallyLongNameDoNotWantToHaveToType.log
cp /tmp/$x /tmp/logs/$x.bak

Yes that would work and do what I want, however if I don't want to have to type the entire name ever...aka using the tab complete perk. Is there a way to do it that way?

For example if in order to type the following line, I used the TAB key to autocomplete the file name (to prevent having to type it out)some of these files are really really long containg numbers undersscores, etc.
Code:
mv /tmp/testfileReallyReallyLongNameDoNotWantToHaveToType.log /tmp/logs/
Furthermore, is there a way to access the mem space that the mv or cp command is using to automatically output the source filename. Could you call that space like

CODE]
mv /tmp/testfileReallyReallyLongNameDoNotWantToHaveToType.log /tmp/logs/%.bak
[/CODE]

How about
Code:
cd /tmp
x=tes
and then use tab completion to get the full name.

If the path is short as described you could just tab complete twice and the add the path change:
Code:
mv /tmp/test[tab] /tmp/test[tab]
Now change file ending and backtrack to start of second path and alter as needed.
