file-rename: display which renames would occur without performing them.
$ rename -n ${'s-foo-bar-'} ${*}
try on your machine
The command "rename -n ${'s-foo-bar-'} ${*}" is used to perform a bulk rename operation on files. Let's break down the components:
- "rename" is the command for renaming files.
- "-n" is an option that stands for "dry-run." It allows you to preview the changes that will be made without actually renaming the files.
- "${'s-foo-bar-'}" is a regular expression pattern to match part of the filenames that you want to rename. In this case, it will search for the string "foo" and replace it with "bar".
- "${*}" is a wildcard that represents all the files in the current directory. It will apply the renaming operation to all the files matching the pattern "s-foo-bar-" in their filenames.
So, when you run this command, it will list all the files that will be renamed (without actually renaming them), showing the changes that will occur.

never run a command you are not sure if it is safe.
