tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

start new:

tmux

start new with session name:

tmux new -s myname

Start the worker:

celery -A tasks worker --loglevel=info -c 2 --pidfile=celery.pid

In another terminal send 6 tasks:

python script.py

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
