+> Rename multiple files.

+- Rename files using simple substitutions (substitute 'foo' with 'bar' wherever found):
+
+`rename {{foo}} {{bar}} {{*}}`
+
+- Dry-run - display which renames would occur without performing them:
+
+`rename -vn {{foo}} {{bar}} {{*}}`
+
+- Do not overwrite existing files:
+
+`rename -o {{foo}} {{bar}} {{*}}`
+
+- Change file extensions:
+
+`rename {{.ext}} {{.bak}} {{*.ext}}`
+
+- Prepend "foo" to all filenames in the current directory:
+
+`rename {{''}} {{'foo'}} {{*}}`
+
+- Rename a group of increasingly numbered files zero-padding the numbers up to 3 digits:
+
+`rename {{foo}} {{foo00}} {{foo?}} && rename {{foo}} {{foo0}} {{foo??}}`
