rename

Renames multiple files.

• Rename files using a Perl Common Regular Expression (substitute 'foo' with 'bar' wherever found):

rename {{'s/foo/bar/'}} {{\*}}

• Dry-run - display which renames would occur without performing them:

rename -n {{'s/foo/bar/'}} {{\*}}

• Convert filenames to lower case:

rename 'y/A-Z/a-z/' {{\*}}

• Replace whitespace with underscores:

rename 's/\s+/_/g' {{\*}}
