### :information_source: Pro Tip!

:point_right: If you have multiple AWS Accounts, you can use bash alias like the following. So you no longer need to pass `--profile` to `aws` tool.

```bash
alias aws-prod="aws --profile work-prod"
alias aws-dev="aws --profile work-dev"
alias aws-self="aws --profile personal"
alias aws="aws --profile work-dev"
```

:point_right: To format `aws` command output into tables, you can pipe output to `column -t`.

```
# aws ec2 describe-instances | jq ...
i-0f112d652ecf13dac c3.x2large fisher.com
i-0b3b5128445a332db t2.nano robinson.com

# aws ec2 describe-instances | jq ... | column -t
