Uninstalling dctlenv

You will need to first remove the line from your shell startup configuration file. This will remove dctlenv from your $PATH.

Then, you just need to remove its root directory:

$ rm -rf `dctlenv root`

Completion scripts

Completion scripts are available to use inside the completions folder.

Bash

# Linux:
$ sudo cp completions/dctlenv.bash /etc/bash_completion.d/dctlenv

# MacOS:
$ sudo cp completions/dctlenv.bash /usr/local/etc/bash_completion.d/dctlenv

Remember to open a new shell to test the functionality.

Zsh

If shell completion is not already enabled in your environment, you will need to enable it. You can execute the following once:

$ echo "autoload -U compinit; compinit" >> ~/.zshrc

Then, place the completion script in your completion folder listed in your fpath if it already exists. Otherwise, you can create a directory, add it to your fpath and copy the file in it:

$ cp completions/dctlenv.zsh > fpath/completion_folder/_dctlenv

Oh-My-Zsh

$ mkdir -p ~/.oh-my-zsh/completions
$ cp completions/dctlenv.zsh ~/.oh-my-zsh/completions/_dctlenv

You will need to start a new shell for this setup to take effect.

Fish

$ cp completions/dctlenv.fish ~/.config/fish/completions/dctlenv.fish

Remember to create the directory if it's not already there mkdir -p ~/.config/fish/completions/.

Remember to open a new shell to test the functionality.
