renamer

renamer

Batch rename files and folders.

Install

Install node then:

$ npm install -g renamer

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

Usage

$ renamer [--regex] [--find <pattern>] [--replace <string>] [--dry-run] <files>

-f, --find        The find string, or regular expression when --regex is set. 
                  If not set, the whole filename will be replaced.
-r, --replace     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. 
-i, --insensitive Enable case-insensitive finds.
-d, --dry-run     Used for test runs. Set this to do everything but rename the file.
-h, --help        Print usage instructions. 

For more information on Regular Expressions, see this useful guide.

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

Globbing

Renamer comes with globbing support built in (provided by node-glob). If you want to override your shell's native expansion behaviour (say, for example it lacks the globstar option), pass the glob expression in single quotes and renamer will expand it. For example, this command operates on all js files, recursively:

$ renamer -f 'this' -r 'that' '**/*.js'

Examples

Simple replace

$ tree -N
.
├── A poem [bad].txt
├── A story [bad].txt

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

$ tree -N
.
├── A poem [good].txt
├── A story [good].txt

Case insenstive finds

$ tree -N
.
├── A video.MPEG4
├── Another video.Mpeg4

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

$ tree -N
.
├── A video.mp4
├── Another video.mp4

Strip out unwanted text:

$ tree -N
.
├── Season 1 - Some crappy episode.mp4
├── Season 1 - Load of bollocks.mp4

$ renamer --find 'Season 1 - ' *

$ tree -N
.
├── Some crappy episode.mp4
├── Load of bollocks.mp4

Simple filename cleanup:

$ tree
.
├── [ag]_Annoying_filename_-_3_[38881CD1].mp4
├── [ag]_Annoying_filename_-_34_[38881CD1].mp4
├── [ag]_Annoying_filename_-_53_[38881CD1].mp4

$ renamer --regex --find '.*_(\d+)_.*' --replace 'Video $1.mp4' *

$ tree
.
├── Video 3.mp4
├── Video 34.mp4
├── Video 53.mp4

Give your images a new numbering scheme:

$ tree
.
├── IMG_5776.JPG
├── IMG_5777.JPG
├── IMG_5778.JPG

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

$ tree
.
├── Image1.jpg
├── Image2.jpg
├── Image3.jpg

do something about all those full stops:

$ tree
.
├── loads.of.full.stops.every.where.jpeg
├── loads.of.full.stops.every.where.mp4

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

$ tree
.
├── 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:

$ tree
.
├── data1.csv
├── data2 (checked by Lloyd).csv
├── data3.xls

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

$ tree
.
├── data1 (checked by Lloyd).csv
├── data2 (checked by Lloyd).csv
├── data3 (checked by Lloyd).xls

rename files and folders, recursively

$ tree
.
├── pic1.jpg
├── pic2.jpg
└── pics
    ├── pic3.jpg
    └── pic4.jpg

$ renamer --find 'pic' --replace 'photo' '**'

$ tree
.
├── photo1.jpg
├── photo2.jpg
└── photos
    ├── photo3.jpg
    └── photo4.jpg

prefix files and folders, recursively

$ tree
.
├── pic1.jpg
├── pic2.jpg
└── pics
    ├── pic3.jpg
    └── pic4.jpg

$ renamer --regex --find '^' --replace 'good-' '**'

$ tree
.
├── good-pic1.jpg
├── good-pic2.jpg
└── good-pics
    ├── good-pic3.jpg
    └── good-pic4.jpg
