This example shows two bash loops that batch-convert files between formats. The first loop processes all GIF files in a folder, using ImageMagick's `convert` to split each animation into numbered frames and then append them vertically into a single image. The second loop transforms every HTML file into a PDF via `wkhtmltopdf`. Both loops rely on shell parameter substitution and `sed` to derive output filenames, echoing each file as it is processed.

Pandoc bash conversion

This visualization demonstrates a user’s workflow of converting and renaming files across directories using shell commands. It shows three distinct bash operations: deleting HTML files in a specific folder, converting sociology files to DOCX via Pandoc, and renaming XML files to HTML using the `rename` utility. The code relies on standard shell scripting constructs and the Pandoc command-line tool, with no graphical or interactive rendering libraries like D3 or Three.js. The data source is the local file system paths referenced in each command, and the rendering approach is purely textual—showing the raw bash scripts rather than any visual output.

Image Magick Cheat Sheet - Fun and easy picture editing in Linux command lIne

This example is a cheat sheet for using ImageMagick from the Linux command line, presented as a Jupyter notebook. It demonstrates two common image-processing tasks: resizing an image while preserving its aspect ratio via the `convert` command with the `-resize` flag, and creating an animated GIF from a sequence of PNG files using `-delay` and `-loop` options. The code relies on the ImageMagick `convert` utility and includes links to external tutorials for reference.

Bash script to process frames and convert then to a video format with ffmpeg

This example demonstrates how to assemble a sequence of numbered JPEG frames into a single video file. It relies on the Bash script to orchestrate the conversion, calling ffmpeg with a specified framerate of 30 frames per second. The command uses the libx264 codec with high profile settings, a constant rate factor of 18, and the yuv420p pixel format to ensure broad compatibility. The input pattern `path_to_file_%04d.jpeg` indicates that frames are named with four-digit zero-padded numbers, which ffmpeg then reads sequentially to produce the final `output.mp4`.

Creating Thumbnails with GraphicsMagick

This example demonstrates a batch image processing workflow using GraphicsMagick’s `gm convert` command. It shows how to automatically generate uniform thumbnails from a folder of PNG images, first cropping each source to a 1920x1000 region offset by (312, 510) pixels, then resizing the crop to 230x120 pixels. The shell script iterates over all PNG files in the `source` directory, processes each one, and saves the results to a `target` folder. The approach relies on Bash array expansion and the `gm` command-line tool’s `-crop` and `-resize` operators.

Bash one-liners

Two Bash one-liners demonstrate how to process files from the command line. The first uses `find` and `xargs` to locate all `*.aln` files, then pipes each filename into a `sh -c` command that runs `cut` to extract the first column, saving the output as a new file with a `.cut` extension. The second one-liner pipes the output of `file` into a redirect, capturing the file type information for every `*.stderr` file into a text file named `file_types`. The examples use standard Unix tools—`find`, `xargs`, `sh -c`, `cut`, `file`, and shell redirection—to perform file discovery and simple text transformation.

Screen Recording to GIF

This example demonstrates a command-line workflow for converting a QuickTime screen recording into an optimized GIF. It first uses ffmpeg to extract frames at 24 fps, then ImageMagick’s `convert` to build a palette from the first frame, remap all frames with `-remap` for color reduction, and finally gifsicle with `--optimize=3` to compress the output. A resize option via gifsicle shows how to scale the final image, while the code notes alternative tools like LICEcap and the trade-offs of uploading MOV files to Twitter.

Screen Recording to GIF

This example shows how to convert a screen recording into an animated GIF using command-line tools. It first generates a color palette from the video with FFmpeg’s `palettegen` filter, then applies that palette with `paletteuse` to produce a high-quality GIF. The workflow also supports optional frame dropping via `fps` and cropping through FFmpeg’s `crop` filter. The code relies solely on FFmpeg and Gifsicle, with QuickTime Player used for the initial recording.

GraphicsMagick Cheat Sheet

This example presents a single-shell cheat sheet for GraphicsMagick, a command-line image processing tool. It demonstrates how to make a non-square image square by adding transparent padding using the `montage` command with `-geometry 1024x1024` and `-background none`. The displayed code shows the exact shell syntax and flags needed to achieve this operation, serving as a quick reference for users. The visualization itself is a static code listing, with the rendering approach being the monospaced text output of the script.
