Tmux & Server Cheat Sheet

Everything I need to run and manage servers on my Hack Club Nest.

Starting a Server in Tmux

1. tmux new -s mysite — create a new tmux session named "mysite"
2. cd ~/mysite — go to the site folder
3. python3 -m http.server 8000 — start the server on port 8000
4. Press Ctrl + B, release, then press D — detach (server keeps running)

Managing Tmux Sessions

• tmux ls — list all running sessions
• tmux attach -t mysite — re-enter the session
• tmux a — attach to the only session (shortcut)
• tmux kill-session -t mysite — kill a specific session
• tmux kill-server — kill ALL tmux sessions

Inside a Tmux Session

• Ctrl + C — stop the running server (but keep tmux open)
• Ctrl + B, then D — detach (leave it running in background)
• Ctrl + D or type exit — close the session entirely

Killing Stray Servers

• lsof -i :8000 — see what's running on port 8000
• fuser -k 8000/tcp — kill whatever's on port 8000
• pkill -f "http.server" — kill all python http.server processes
• kill -9 <PID> — force kill a specific process

Clean Slate Reset

1. fuser -k 8000/tcp
2. pkill -f "http.server"
3. tmux kill-server
4. lsof -i :8000 (should return nothing)

Folder Navigation

• cd ~ — go to home directory
• cd ~/mysite — go to main site folder
• ls — list files in current folder
• pwd — print current directory
• mkdir foldername — make a new folder
