Generally only used by tab-completion. compare Compare packages between conda environments. config Modify configuration values in .condarc. content-trust Signing and verification tools for Conda create Create a new conda environment from a list of specified packages. deactivate Deactivate the current active conda environment. doctor Display a health report for your environment. export Export a given environment info Display information about current conda install. init Initialize conda for shell interaction. install Install a list of packages into a specified conda environment. list List installed packages in a conda environment. notices Retrieve latest channel notifications. package Create low-level conda packages. (EXPERIMENTAL) remove (uninstall) Remove a list of packages from a specified conda environment. rename Rename an existing environment. repoquery Advanced search for repodata. run Run an executable in a conda environment. search Search for packages and display associated information using the MatchSpec format. tos A subcommand for viewing, accepting, rejecting, and otherwise interacting with a channels Terms of Service (ToS). This plugin periodically checks for updated Terms of Service for the active/selected channels. Channels with a Terms of Service will need to be accepted or rejected prior to use. Conda will only allow package installation from channels without a Terms of Service or with an accepted Terms of Service. Attempting to use a channel with a rejected Terms of Service will result in an error.
