Move files and folders.
SYNTAX
     mv [options] source_file target_file
     mv [options] source_folder target_folder
OPTIONS
     -n	     Do not overwrite any existing file.
     -i	     Prompt before moving a file that would overwrite an existing file.
	     A response `y' or `Y', will allow the move to proceed
	    (writes to standard error)
     -f	     Always Overwrite destination files
             (Do not prompt for confirmation)
     -v	     Verbose, show filenames.
The -n and -v options are non-standard and their use in scripts is not recommended.
EXAMPLES
Move all files with names ending in ".jpg" from the current folder
to the Documents directory
  mv *.jpg ~/Documents
Move the "Documents" folder to "Documents backup".
  mv Documents "Documents backup"
quotes are needed because of the space in the folder name.
Renaming a bunch of file extensions
e.g. change *.txt into *.htm
  for f in *.txt; do mv ./"$f" "${f%txt}htm"; done
