The script …

• Creates new reservations if it’s non-existent with count.
• Update an existing reservation by increasing or decreasing count.
• Delete a reservation if no instances are present or none are running.
• Print a summary at end of the script.

It doesn’t have to be dos2unix but can be any command.

Run it on all files.

find . -type f -exec dos2unix {} +

Run it on all shell files only.

find . -type f -name "*.sh" -exec dos2unix {} +

Back in the day, my cloud bill was anywhere between $10-20 per month because I was hosting a VM.

I converted from WordPress site to Jekyll, a static site generator hosted for free at GitHub.

My photo gallery is hosted in AWS S3. I use node.js programs to generate the galleries.

My total bill this month is $0.13. It will climb a few cents as I upload more photos.

User is asked to match the string. If there’s a match, it continues.

If there’s no match, it will exit.

confirm() {
  CHARNUM=6
  CHARSET='A-Za-z0-9'
  # Generate random string
  RANDOM_STRING=$(LC_ALL=C tr -dc $CHARSET </dev/urandom | head -c $CHARNUM)
  printf "%s\n" "Please confirm Code to continue: $RANDOM_STRING"
  read -r -p "Code: " USER_INPUT
  if [[ "$USER_INPUT" != "$RANDOM_STRING" ]]; then
    echo "❌ Code does not match! Exiting!"
    exit 1
  fi
  echo "✅ Code matched!"
  echo "Shutting down server!"
}

#!/bin/bash

comment=$1
if [[ -z $comment ]]; then
  echo "Usage: $0 'put your comment here'"
  exit
fi

git add .
git commit -am "$comment"
git push

To use the script, simply execute ./gitPush.sh ‘put your git comment here’

The script will add, commit and push it to your remote repository.

I should really set it to a static IP address, but that’s another story.

Doing a git pull and a git push no longer works since the remote URL changed.

To update to a new remote location, simply run the command below.

git remote set-url origin http://192.168.68.105:3000/ulysses/scripts.git

If you use SSH, use the SSH remote link instead of HTTP.
