Bash script to create an isolated environment using namespaces and cgroups

Isolate Script

This script creates an isolated environment using Linux namespaces and cgroups, executes a provided Bash script, and then cleans up the environment. It ensures that any changes made within the isolated environment do not affect the host system.

How It Works

  1. Argument Check: The script checks if a Bash script file is provided as an argument.
  2. File Existence Check: It verifies if the provided file exists.
  3. Cgroup Creation: A cgroup is created to limit the number of processes to 50.
  4. Namespace Creation: The script creates new PID and UTS namespaces using unshare.

Extracting / Exporting custom emoji from Slack

Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.

Follow along...

Dump, compare and check db integrity

Database Backup and comparation

Dump Postgres DB

pg_dump --data-only --inserts -h <DB_URL> -U <DB_USER> -f <FILE_NAME_TO_CREATE.sql> <DB_NAME>

Notes:

  • --data-only will dump only data to be inserted (not tables strcuture and relations)
  • --inserts will force to use INSERT statements and not COPY to avoid driver issues later on
