Setting up Command auto completion for AWS CLI

Once you have installed the AWS CLI, it has the feature to auto complete the commands for you at the press of a TaB key. I am using a MAC & the commands here are pertaining to the Mac OS & the zsh shell is used.

To enable this, execute the foll. commands

  1. Check the location of aws_completer
    which aws_completer

  2. Check the shell using command echo $SHELL

  3. Find the profile script of shell
    ls -a ~/

In my case its the zsh & this shell does not have a profile script .zshrc created by default even if you are using the shell

  1. Create the file using command:
    Touch ~/.zshrc

  2. Add the path of the aws_completer to this:

export PATH

Add the below command to the .zshrc file so that the command completion works every time you open the shell

autoload bashcompinit && bashcompinit
autoload -Uz compinit && compinit

  1. To enable command completion run the below command
    complete -C '/usr/local/bin/aws_completer' aws

  2. Execute the command below to reproduce the above changes in current shell
    source ~/.zshrc

Verify the command completion using the

aws i(TAB key press)

For other OS's , please refer to the below documentation by AWS
