4) Verify AWS CLI installation

$ aws

-bash: aws: command not found

$ 

Here in my case executable is not found, so need to add the aws executable to OS's PATH environment variable.

Following is the path.

$ ~/Library/Python/3.6/bin/

__pycache__/           aws_zsh_completer.sh   pyrsa-encrypt-bigfile  rst2html.py            rst2odt_prepstyles.py  rstpep2html.py

aws                    jp.py                  pyrsa-keygen           rst2html5.py           rst2pseudoxml.py       wheel

aws.cmd                pyrsa-decrypt          pyrsa-priv2pub         rst2latex.py           rst2s5.py              

aws_bash_completer     pyrsa-decrypt-bigfile  pyrsa-sign             rst2man.py             rst2xetex.py        

aws_completer          pyrsa-encrypt          pyrsa-verify           rst2odt.py             rst2xml.py             

In this example i am adding the path to my "bash_profile" (~/.bash_profile)

PATH="~/Library/Python/3.6/bin:$PATH"

$ source ~/.bash_profile

Type aws as command to verify.

$ aws

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]

To see help text, you can run:

  aws help

  aws <command> help

  aws <command> <subcommand> help

aws: error: the following arguments are required: command

** AWS CLI is installed successfully **
