file-rename:tldr:3a875

The command you provided is:

rename -f ${'s-foo-bar-'} ${*}

This command uses the rename utility to rename multiple files at once.

Here is the breakdown of the different elements in the command:

• rename: It is the command to rename files.
• -f: It is an option that forces the renaming process without asking for confirmation.
• ${'s-foo-bar-'}: This is the first argument or parameter passed to rename. It specifies the pattern to search for in the filenames to be renamed. In this case, it is 's-foo-bar-', which means that any occurrence of "foo" should be replaced with "bar" in the filenames.
• ${*}: This is the second argument or parameter of the command. It represents all the filenames that should be renamed, typically passed as command-line arguments using wildcards (*). It specifies the files on which the rename pattern should be applied.

By executing this command, the rename utility will search for any occurrences of "foo" in the filenames specified by ${*} and replace them with "bar". The -f option ensures that the renaming happens without asking for confirmation.
