Every command except completion, version, and help has its own page.

version

nemo version prints the version and exits. It takes no arguments or options. The version string is embedded at compile time from cmd/VERSION.

help

nemo help prints general usage. nemo help <command> prints that command’s description, arguments, and options.

--help or -h does the same on any command, for example nemo hide --help.

Shell completion

nemo completion <shell> prints a completion script for bash, zsh, fish, or powershell. Once loaded, Tab completes commands and flags.

The install script sets this up for you when your shell is zsh. To do it by hand, run this once:

mkdir -p ~/.nemo && nemo completion zsh > ~/.nemo/_nemo && echo '[ -s ~/.nemo/_nemo ] && source ~/.nemo/_nemo' >> ~/.zshrc

Open a new terminal afterwards. The script is saved to a file, so shell startup does not run nemo. Run the first half of the command again after upgrading nemo to refresh it.

nemo must be on your PATH for completion to trigger. The source line has to come after compinit in ~/.zshrc, which is the case when you append it to the end.

For other shells, run nemo completion <shell> --help for the setup steps.
