texdoc [-l] [-s] [-I] [options] query

texdoc finds and opens documentation for TeX and LaTeX packages installed in the TeX Live distribution. Given a package name, it locates the corresponding PDF manual or documentation file and opens it in the default viewer.
The -l flag lists all matching documentation files when multiple exist for a package. Interactive mode (-I) presents a numbered list for selection. Search mode (-s) performs a broader search across the documentation tree, finding documents that mention the query term even if they don't match the package name directly. The -f flag shows file paths without opening them.
