Those of you who are used to Windows systems will appreciate the fact that you get “do you wish to overwrite?” warnings whenever you try and copy/move/rename a file, but the file already exists at the new location.
However, mv, by default, will not show any warning and will silently overwrite files. To prevent mv from overwriting files, use the
-n option like so:
Even better, you can also add the verbose flag (
-v), and mv will tell you what files were moved and which weren’t.
Excluding Directories Using Bash Extensions
In most bash shells, you can exclude certain directories/files from the move command using
!(exclude_pattern) syntax. This is really useful to quickly move all files/directories in the current working directory into a new sub-directory, while excluding the new sub-directory from the move:
Please note that

shopt built-in. Bash will expand
