Commands

The tool speaks fluent command-line. Below is its full vocabulary, arranged by mood and mission. When in doubt, remember that commands are lower-case, arguments go after a space, and sarcasm is optional but encouraged.

Basic Commands

  • ? / help – Prints the built-in help text. Think of it as the in-app fortune cookie.

  • autosave – Toggles autosave of your last project/database/activity. Perfect for the indecisive.

  • number – When shown a list, type its number to jump straight there. Spatial navigation for impatient humans.

  • l – Re-list the current options when you’ve scrolled past oblivion.

  • n – Next page of options. No swiping required.

  • p / p <page> – Previous page or jump directly to page. Because guessing isn’t fun.

  • h – Shows recent history of selected projects, databases, and activities. Nostalgia mode.

  • wh – Writes that history to a timestamped text file. Scrapbooking, anyone.

  • q / quit – Exit the browser gracefully.

  • cp – Nukes saved preferences (dev tool). Use only if you enjoy rebuilding settings from scratch.

Project Commands

  • lpj – Lists all available projects.

  • backup [directory] – Backup the current project into a .tar.gz. Provide a directory if you insist on tidiness; otherwise the default location is used.

  • restore <archive> [--project NAME] [--overwrite] – Restores a project from an archive. You can rename it on the fly, force overwrites (after confirming you really, really mean it), and the browser will switch to the restored project automatically.

Database Commands

  • ldb – Lists every database in the current project.

  • db <name> – Switches to the specified database instantly.

  • s [needle] – Searches activity names inside the current database. Combine with:

    • -loc {LOCATION} to filter by location.

    • -cat {CAT::SUBCAT::…} to zero in on categories.

    • -rp {REFERENCE PRODUCT} to hunt by reference product.

    • -cas {000000-00-0} for CAS-number sleuthing (biosphere databases only).

Activity Commands

  • a <id> – Jumps straight to an activity by code or integer ID (for BW25).

  • aa [name] – Lists all activities in the current database, optionally sorted by name.

  • lprods [name] – Lists only product-like nodes in the current database (product and process_with_reference_product), optionally sorted by name.

  • i / ii – Shows concise or extended activity info. ii is basically i but more intimate.

  • r – Picks a random activity. Because serendipity 💜.

  • u, up, uu, un – Variations on “show upstream technosphere inputs”, adding pedigree, formulas, or uncertainty details respectively.

  • d – Shows downstream consumers of the current activity.

  • b – Lists biosphere flows for the current activity.

  • pe / pei – Displays production exchanges and their detailed metadata.

  • cfs – Prints characterization factors for the current method/biosphere activity combo.

  • G – Runs an LCIA on the current activity for the selected method(s). If the selected node is a plain process, G now refuses gracefully, lists products from that process’ production exchanges as selectable options, and lets you pick one before running G again. Multiverse-friendly (i.e.: if a full method is selected, and not a specific category and subcategory, it will do the LCIA of all the categories and subcategories of the method).

  • ta / te – After an LCIA, list top activities or top emissions.

  • ca [cutoff] – Prints a recursive contribution analysis, optionally trimming at cutoff.

  • sc [cutoff] – Similar, but for the supply chain view.

  • add – Adds the current activity to the temporary analysis list.

  • lt – Lists everything in that temporary list (a.k.a. list in earlier docs).

  • clear – Empties the temporary list; therapeutic but irreversible.

  • G C – (Typed as GC) Launches multi-activity LCIA for the temporary list plus the fully specified method.

  • GCH – Draws a charming ASCII bar chart from the most recent GC results 🤓.

Method Commands

  • lm – Lists methods (or namespaces) available in the current project.

  • mi – Shows metadata for the fully specified method/category/subcategory.

Parameter Commands

  • lpam [-f] [-g {GROUP}] – Lists all project/database/activity parameters. -f shows every column; -g filters by group.

  • lpamg – Lists parameter groups.

  • ap [-f] – Shows parameters for the current activity (-f for verbose mode).

  • dp [-f] – Displays parameters for the current database.

  • pp [-f] – Prints project-level parameters.

  • fp <name> – Finds a parameter by exact name across scopes.

  • sp <pattern> – Wildcard-friendly parameter.

Misc Commands

  • tsv [filename] – Writes the most recent tabulated results to TSV.

  • wh – Already mentioned above, but worth remembering for logging your wanderings.

  • help – Alias for ?, in case muscle memory from every other CLI kicks in.

With this lexicon, you’re ready to charm the tool into revealing every LCA secret it knows. Happy exploring!
