#340 Image/File Renamer
Ever have a bunch of files (like screenshots) that you want to give a standardised, sequential name and possibly generate a markdown link? Here’s a script for that.
Notes
The image-renamer.sh script is a little utility for renaming a bunch of files.
I use this for including screenshots in markdown files.
It is a simple bash script that just takes a couple of options then iterates and renames accordingly. It spits out the resulting filename in a few different formats for different usages.
$ ./image-renamer.sh -h
Usage:
./image-renamer.sh <source_path> [-b base_name] [-p print_style] [-s sort_order]
Example: ./image-renamer.sh ./assets/sample-data -b image- -p md -s time
Options:
<source_path> Path to the source directory containing images.
-b base_name Optional stem name for the renamed files (default: "image-").
-p print_style Optional output style for the renamed files (default: "md").
Supported styles: md, html, plain.
-s sort_order Optional order of files to process (default: "time").
Supported orders: time, name.
-h Show this help message.
Test Data
Before all of the following tests, I create a fresh data set in ./example-data with the make-test-data.sh script:
$ ./make-test-data.sh
Making a fresh copy of ./example-data
Renaming files in a relative folder
$ ./image-renamer.sh "example-data/sample-*.png"
So when I include that output in this markdown file, we see:
HTML Output
$ ./image-renamer.sh "example-data/sample-*.png" -p html
<a href="example-data/image-1.png">image-1</a>
<a href="example-data/image-2.png">image-2</a>
<a href="example-data/image-3.png">image-3</a>
<a href="example-data/image-4.png">image-4</a>
<a href="example-data/image-5.png">image-5</a>
<a href="example-data/image-6.png">image-6</a>
<a href="example-data/image-7.png">image-7</a>
<a href="example-data/image-8.png">image-8</a>
Plain Output
$ ./image-renamer.sh "./example-data/sample*.png" -p text
./example-data/image-1.png
./example-data/image-2.png
./example-data/image-3.png
./example-data/image-4.png
./example-data/image-5.png
./example-data/image-6.png
./example-data/image-7.png
./example-data/image-8.png
Referencing files in the current folder
$ cd example-data/
$ ../image-renamer.sh "sample*.png"
Changing the base name
$ ./image-renamer.sh "./example-data/sample*.png" -b graphics-
