Enable AWS CLI Autocomplete for Snap package

I installed the aws-cli via snap using

sudo snap install aws-cli --classic

If you’ve also installed AWS CLI using Snap on Ubuntu or other Linux distributions, you may have stumbled upon the same issue that the aws_completer is not placed in the usual /usr/local/bin/aws_completer

🔗 Locate the AWS completer

Lets try to locate the path of aws_completer

which aws_completer return is empty. As no path is shown, locating it using find:

$ find / -name aws_completer 2>/dev/null

/snap/aws-cli/1441/aws/dist/aws_completer
/snap/aws-cli/1441/bin/aws_completer
/snap/aws-cli/1443/aws/dist/aws_completer
/snap/aws-cli/1443/bin/aws_completer

Snap packages use internal versioned folders (e.g. 1441, 1443) that change on update, making hard-coded paths impractical. This makes configuring autocomplete tricky.

However, Snap maintains a /snap/aws-cli/current symlink to the active version. Link this to a location in your $PATH instead.

🛠️ 1. Create a stable symlink in your PATH

Use the snap's current alias to avoid version-specific paths.

This ensures autocomplete continues working even after AWS CLI updates.

sudo ln -sf /snap/aws-cli/current/bin/aws_completer /usr/local/bin/aws_completer

✍️ Step 2: Add completion setup to your shell

For Bash (`~/.bashrc`):

complete -C '/usr/local/bin/aws_completer' aws

For Zsh (`~/.zshrc`):

autoload bashcompinit && bashcompinit
autoload -Uz compinit && compinit
complete -C '/usr/local/bin/aws_completer' aws

🔄 Step 3: Reload your shell

Apply changes:

source ~/.bashrc  # or source ~/.zshrc

Press Tab after typing a partial aws command:

aws s3 <TAB><TAB>

🤖 Step 4 (Optional): Activate AWS CLI v2 Auto‑Prompt

Beyond tab completion, AWS CLI v2 offers an interactive auto‑prompt that guides your input after pressing Enter

nable it permanently (default profile):

aws configure set cli_auto_prompt on-partial

Or for just your session:

bashCopyEdiexport AWS_CLI_AUTO_PROMPT=on-partial

This mode is especially helpful when you're exploring less familiar commands
