Bulk rename of files in directory tree

I needed to remove parts of file-names with broken encoding from directory structure.

Example of the name with bad encoding:

Snímka000.jpg

Requested output example:

000.jpg

I used program find to dump directory tree chained with program rename to do bulk renaming via regular expressions. Here is how it looks like:

find . | rename 's/([^(\/Sn)]*)\/Sn([^0-9]*)([0-9]*\.jpg)$/$1\/$3/'

To check the results before proper execution, you can use flag "-n":

find . | rename -n 's/([^(\/Sn)]*)\/Sn([^0-9]*)([0-9]*\.jpg)$/$1\/$3/'

More info:

man rename
man find

By default, I will not analyze chained command here, but I will answer your questions, if case of need in place.
