Renaming files with mv without typing the name two times

An alternative is:

  mv file.name !#:1.bak
  cp process.log !#:1.old

!#:1 expands to the word with index 1.

And it supports regex replace as well

    $ echo foobar !#:1:s/foo/bar
    echo foobar barbar
    foobar barbar

I didn't know about the Ctrl-Alt-E so that's useful to know when using a new computer or a shared user account. I have `shopt -s histverify` set in my own bashrc. It's a useful sanity check when using history expansion. After typing the command, press Enter to see what it expands to, verify that it's what I intend and hit Enter a second time to confirm the comand.
