Linux/Mac users may need to run the above with sudo

Usage

Usage
$ renamer <options> <files>

-f, --find <undefined>     The find string, or regular expression when --regex is set.
                           If not set, the whole filename will be replaced.
-r, --replace <undefined>  The replace string. With --regex set, --replace can reference
                           parenthesised substrings from --find with $1, $2, $3 etc.
                           If omitted, defaults to a blank string. The special token
                           '{{index}}' will insert an incrementing number per file
                           processed.
-e, --regex                When set, --find is intepreted as a regular expression.
-d, --dry-run              Used for test runs. Set this to do everything but rename the file.
-i, --insensitive          Enable case-insensitive finds.
-v, --verbose              Use to print additional information.
-h, --help                 Print usage instructions.

Don't forget to test your rename first using --dry-run!

Recursing

Renamer comes with globbing support built in (provided by node-glob), enabling recursive operations. To recurse, use the ** wildcard where a directory name would appear to apply the meaning "any directory, including this one".

For example, this command operates on all js files in the current directory:

$ renamer --find this --replace that '*.js'

this command operates on all js files, recursively:

$ renamer --find this --replace that '**/*.js'

this command operates on all js files from the lib directory downward:

$ renamer --find this --replace that 'lib/**/*.js'

Bash users without globstar will need to enclose the glob expression in quotes to prevent native file expansion, i.e. '**/*.js'

Examples

Simple replace

$ renamer --find '[bad]' --replace '[good]' *

Before	After
. ├── A poem [bad].txt ├── A story [bad].txt	. ├── A poem [good].txt ├── A story [good].txt

Case insenstive finds

$ renamer --insensitive --find 'mpeg4' --replace 'mp4' *

Before	After
. ├── A video.MPEG4 ├── Another video.Mpeg4	. ├── A video.mp4 ├── Another video.mp4

Strip out unwanted text

$ renamer --find 'Season 1 - ' *

Before	After
. ├── Season 1 - Some crappy episode.mp4 ├── Season 1 - Load of bollocks.mp4	. ├── Some crappy episode.mp4 ├── Load of bollocks.mp4

Simple filename cleanup

. ├── [ag]_Annoying_filename_-_3_[38881CD1].mp4 ├── [ag]_Annoying_filename_-_34_[38881CD1].mp4 ├── [ag]_Annoying_filename_-_53_[38881CD1].mp4	. ├── Video 3.mp4 ├── Video 34.mp4 ├── Video 53.mp4

Give your images a new numbering scheme

$ renamer --replace 'Image{{index}}.jpg' *

do something about all those full stops

$ renamer --regex --find '\.(?!\w+$)' --replace ' ' *

Before	After
. ├── loads.of.full.stops.every.where.jpeg ├── loads.of.full.stops.every.where.mp4	. ├── loads of full stops every where.jpeg ├── loads of full stops every where.mp4

if not already done, add your name to a load of files

$ renamer --regex --find '(data\d)(\.\w+)' --replace '$1 (checked by Lloyd)$2' *
