This script can help you find and remove unused AWS snapshots and volumes.

There is hardcoded list of regions that it searches, adjust the value to suit your needs.

Use snapshot.py snapshot-report to generate report.csv containing information about all snapshots.

snapshot.py snapshot-cleanup lets you interactively delete snapshot if it finds it is referencing unexisting resources.

# Please note, the commands below will create unreadable files and should be 
# used for testing file size only. If you're looking for something that has
# lines in it, use /dev/urandom instead of /dev/zero. You'll then be able to
# read the number of lines in that file using `wc -l large-file.1mb.txt`

# Create a 1MB file
dd if=/dev/zero of=large-file-1mb.txt count=1024 bs=1024

# Create a 10MB file
dd if=/dev/zero of=large-file-10mb.txt count=1024 bs=10240

# Update 2023-07-20:
# I've recently switched to installing `zsh` via `conda` which is a lot less hassle.
# I added it to start automatically in `tmux` with
# `set-option -g default-shell "~/miniconda3/envs/default/bin/zsh"`
#
# # Install Zsh on Sherlock
# Installs Zsh with Oh-My-Zsh without root privileges 
# on Stanford's Sherlock (https://sherlock.stanford.edu) for use in tmux
