fuelup has a TOML settings file at .fuelup/settings.toml. The schema for this file is not part of the public interface for fuelup - the fuelup CLI should be used to query and set settings.

Generate Shell Completions

Enable tab completion for Bash, Fish, Zsh, or PowerShell. The script prints output on stdout, allowing one to re-direct the output to the file of their choosing. Where you place the file will depend on which shell, and which operating system you are using. Your particular configuration may also determine where these scripts need to be placed.

Here are some common set ups for the supported shells under Unix and similar operating systems (such as GNU/Linux). For these settings to take effect, you may have to log out and log back into your shell session.


Completion files are commonly stored in /etc/bash_completion.d/ for system-wide commands, but can be stored in ~/.local/share/bash-completion/completions for user-specific commands.

mkdir -p ~/.local/share/bash-completion/completions
fuelup completions --shell=bash >> ~/.local/share/bash-completion/completions/fuelup

BASH (macOS/Homebrew)

Homebrew stores bash completion files within the Homebrew directory. With the bash-completion brew formula installed.

mkdir -p $(brew --prefix)/etc/bash_completion.d
fuelup completions --shell=bash > $(brew --prefix)/etc/bash_completion.d/fuelup.bash-completion


Fish completion files are commonly stored in $HOME/.config/fish/completions.

mkdir -p ~/.config/fish/completions
fuelup completions --shell=fish > ~/.config/fish/completions/


ZSH completions are commonly stored in any directory listed in your $fpath variable. To use these completions, you must either add the generated script to one of those directories, or add your own to this list.

Adding a custom directory is often the safest bet if you are unsure of which directory to use. First create the directory; for this example we'll create a hidden directory inside our $HOME directory:

mkdir ~/.zfunc

Then add the following lines to your .zshrc just before compinit:


Now you can install the completions script using the following command:

fuelup completions --shell=zsh > ~/.zfunc/_fuelup


The powershell completion scripts require PowerShell v5.0+ (which comes with Windows 10, but can be downloaded separately for windows 7 or 8.1).

First, check if a profile has already been set

Test-Path $profile

If the above command returns False run the following

New-Item -path $profile -type file -force

Now open the file provided by $profile (if you used the New-Item command it will be ${env:USERPROFILE}\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1).

Next, we either save the completions file into our profile, or into a separate file and source it inside our profile. To save the completions into our profile simply use

fuelup completions --shell=powershell >> ${env:USERPROFILE}\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1


Elvish completions are commonly stored in epm-managed directories.

fuelup completions --shell=elvish > ~/.local/share/elvish/lib/fuelup.elv

Then in rc.elv, add the following line to activate the generated completions.

use fuelup
