Rename files in linux / bash using mv command without typing the full name two times
View mv.sh
# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.

# - imv from renameutils
# - Ctrl-W Ctrl-Y Ctrl-Y (cut last word, paste, paste)
