HOW TO:

---

Recommended To 1st Install the AWS CLI version 2 on Linux

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install -i /usr/local/aws-cli -b /usr/local/bin

aws --version

which aws # OUTPUT /usr/local/bin/aws

configure aws-cl

Mini script to help start, stop and check the status/public ip address for your aws ec2 via aws-cli

1. Add the ec2run.sh file to Bash terminal or zsh:

 # create a dot script directory/folder to house all scripts
mkdir ~/home/$USER/.scripts
cd ~/home/$USER/.scripts 

2. download script file into ~/home/$USER/.scripts and Edit

2.1 download

wget  https://gist.githubusercontent.com/AllieUbisse/01f1f137a838b3898ddedc000cee1942\
/raw/f22f9b40ec0ad46be93bfc871b1427f7f3ebbd3c/ec2run.sh
 
# make script executable
chmod +x ec2run.sh

2.2 # Add the Instance ID to script, replacing INSTANCE_ID=i-XXXXXXXXXXXXXXXXX.

Vim hotkeys: press I to insert/edit then when done hit Esc to exit editing mode --> now hit Shift + : then wq + ENTER

# I use vim for scripting
vim ~/home/$USER/.scripts/ec2run.sh

3. Append alias to ~/.bashrc or/& ~/.zshrc

echo "#####################AWS ALIAS START###################" >> ~/.bashrc 
echo `alias ec2run=/home/$USER/.scripts/ec2run.sh`  >>~/.bashrc 
echo "#####################AWS ALIAS END###################" >>~/.bashrc 

# update changes to the terminal
source ~/.bashrc 

4. Lets use the script

4.1 start EC2 instance

ec2run start

4.2 check status / get public IP for EC2 instance

ec2run status

4.3 Stop the EC2 instance

ec2run stop
