This command opens a list of selected files in an external editor.
|
||
|
|
After you edit and save the file, it will generate a shell script
|
||
|
|
which does bulk renaming according to the changes you did in the file.
|
||
|
|
|
||
|
|
This shell script is opened in an editor for you to review.
|
||
|
|
After you close it, it will be executed.
