Report an inaccuracy

shellmap covers 227 commands and 176 task pages across five shells. Some of those equivalents will have edge cases we missed — flag-renames in a new util-linux release, a PowerShell 7 vs 5.1 divergence we got backwards, a macOS BSD vs GNU mismatch on a coreutils flag.

When you write in, please include:

• The page URL (e.g. /cmd/grep).
• The shell + version where the snippet misbehaves (bash --version, $PSVersionTable).
• The OS / distro (uname -a, sw_vers, winver).
• What the snippet does on your machine vs what the page claims.

Request a task page

If you searched for a shell-task answer and landed on a competitor because shellmap didn't have it, that's the most useful signal we can get. Tell us the search query you typed and the closest existing task page (if any), and it goes on the build list.

Embedding & the embed API

The widget at /embed-demo is documented end-to-end. If you're hitting a CSP rejection, a shadow-DOM styling clash, or you want to embed shellmap inside a larger documentation toolchain (Docusaurus, MkDocs, MDX), email us with the host page URL and the rendered output so we can repro quickly.

Licensing & partnerships

Want to mirror a slice of the catalog inside an internal developer portal, ship a shellmap-flavoured cheatsheet at a conference, or partner on shell-tooling content? The terms of use covers the default boundary; email us for anything beyond it.

What we can't help with

A few things are outside scope — sending them in just adds latency to the things we can answer:

• Free one-on-one scripting help— we don't debug your specific pipeline. Stack Overflow, the shell's tag on Reddit, and the project's own GitHub Discussions are better venues for that.
• Security-emergency advice— if a command on shellmap matches an active incident on your side, call your usual security responder; don't wait on email.
• Generic SEO / link-building outreach— we don't exchange links, and we don't accept sponsored content for the command corpus. Editorial integrity is the whole value prop.
