The zmv -i '${(*)-log}' '${$1-txt}' command is used in the Zsh shell to rename multiple files.

Here's the breakdown of the command:

• zmv: This is the command itself. It is specific to the Zsh shell and is used for file renaming.
• -i: This option stands for "interactive" and prompts for confirmation before renaming each file.
• '${(*)-log}': This is the pattern to match the files to be renamed. The (*) part captures any part of the filename, and the log is the default value if no match is found.
• '${$1-txt}': This is the replacement pattern. The $1 refers to the captured part of the filename from the matching pattern, and txt is the replacement value.

In simple terms, this command renames all files by replacing the ending "log" with "txt". For example, a file named "file1.log" would be renamed to "file1.txt".
