Create a module exporting a class which defines a replace method. $ renamer -find '/one/i' -replace 'two' ONE.jpgįor more complex renames, or if you just prefer using code, you can write a replace function.

The case-insensitive pattern /one/i matches the input file ONE.jpg, renaming it to two.jpg. Simple example using a regular expression literal. $ cat files.txt | renamer -find jpeg -replace jpg Same again but with a hand-rolled input of filenames and glob patterns. mtime -20m | renamer -find jpeg -replace jpg This example operates on files modified less than 20 minutes ago. This approach is useful for crafting a specific input list using tools like find. If no filenames or patterns are specified, renamer will look for a newline-separated list of filenames on standard input. $ renamer -find jpeg -replace jpg *Īs above but operates on all files and folders recursively.

This trivial example will replace the text jpeg with jpg in all file and directory names in the current directory.
