try on your machine
This command is using the "rename" command to rename files. Here is a breakdown of each part of the command:
-
"${-ext}" - This is a variable value that represents the file extension of the file(s) you want to rename.
-
"${-bak}" - This is another variable value that represents the desired new file extension you want to replace the original extension with.
-
"${*-ext}" - This variable value represents the filename without the original file extension.
In summary, this command is designed to rename a file by replacing its existing file extension (${ext}) with a new file extension (${bak}). The "${*-ext}" part is used to get the filename without the original extension.
