rga: ripgrep, but also search in PDFs, E-Books, Office documents, zip, tar.gz, etc.
rga is a line-oriented search tool that allows you to look for a regex in a multitude of file types. rga wraps the awesome ripgrep and enables it to search in pdf, docx, sqlite, jpg, movie subtitles (mkv, mp4), etc.
For more detail, see this introductory blogpost: https://phiresky.github.io/blog/2019/rga--ripgrep-for-zip-targz-docx-odt-epub-jpg/
rga will recursively descend into archives and match text in every file type it knows.
Here is an example directory with different file types:
demo/
├── greeting.mkv
├── hello.odt
├── hello.sqlite3
└── somearchive.zip
├── dir
│ ├── greeting.docx
│ └── inner.tar.gz
│ └── greeting.pdf
└── greeting.epub
Available Adapters
rga --rga-list-adapters
Adapters:
-
ffmpeg
Uses ffmpeg to extract video metadata/chapters and subtitles
Extensions: .mkv, .mp4, .avi
-
pandoc
Uses pandoc to convert binary/unreadable text documents to plain markdown-like text
Extensions: .epub, .odt, .docx, .fb2, .ipynb
-
poppler
Uses pdftotext (from poppler-utils) to extract plain text from PDF files
Extensions: .pdf
-
zip
Reads a zip file as a stream and recurses down into its contents
Extensions: .zip
-
tar
Reads a tar file as a stream and recurses down into its contents
Extensions: .tar, .tar.gz, .tar.bz2, .tar.xz, .tar.zst
-
sqlite
Uses sqlite bindings to convert sqlite databases into a simple plain text format
Extensions: .db, .db3, .sqlite, .sqlite3
Mime Types: application/x-sqlite3
The following adapters are disabled by default, and can be enabled using --rga-adapters=+pdfpages,tesseract:
-
pdfpages Converts a pdf to it's individual pages as png files. Only useful in combination with tesseract
Extensions: .pdf
-
tesseract Uses tesseract to run OCR on images to make them searchable. May need -j1 to prevent overloading the system. Make sure you have tesseract installed.
Extensions: .jpg, .png
USAGE:
rga [FLAGS] [OPTIONS] PATTERN [PATH ...]
FLAGS:
--rga-accurate
Use more accurate but slower matching by mime type
By default, rga will match files using file extensions. Some programs, such as sqlite3, don't care about the file extension at all, so users sometimes use any or no extension at all. With this flag, rga will try to detect the mime type of input files using the magic bytes (similar to the `file` utility), and use that to choose the adapter. Detection is only done on the first 8KiB of the file, since we can't always seek on the input (in archives).
-h, --help
Prints help information
--rga-list-adapters
List all known adapters
--rga-no-cache
Disable caching of results
By default, rga caches the extracted text to a database in ~/.cache/rga if it is small enough. This way, repeated searches on the same set of files will be much faster. If you pass this flag, all caching will be disabled.
--rg-help
Show help for ripgrep itself
--rg-version
Show version of ripgrep itself
-V, --version
Prints version information
OPTIONS:
--rga-adapters=<adapters>...
Change which adapters to use and in which priority order (descending)
"foo,bar" means use only adapters foo and bar. "-bar,baz" means use all default adapters except for bar and baz. "+bar,baz" means use all default adapters and also bar and baz.
--rga-cache-compression-level=<cache-compression-level>
default: 12
--rga-cache-max-blob-len <cache-max-blob-len>
Max compressed size to cache
Longest byte length (after compression) to store in cache. Longer adapter outputs will not be cached and recomputed every time.
default: 2000000
--rga-max-archive-recursion=<max-archive-recursion>
Maximum nestedness of archives to recurse into [default: 4]
-h shows a concise overview, --help shows more detail and advanced options.
All other options not shown here are passed directly to rg, especially
PATTERNDevelopment
To enable debug logging:
export RUST_LOG=debug
export RUST_BACKTRACE=1
Also rember to disable caching with --rga-no-cache or clear the cache in ~/.cache/rga to debug the adapters.
