[NOTE] Unix Command Book

Basic concepts in ML/AI algorithms, and some simple algorithms implementations. There are so many operators and variants of them; this post only covers the most basic ones.

Environment Setups

• Module loading system

# Modules loc: /usr/share/Modules/modulefiles
module avai

Process and Sessions

• Terminate a process with PID

kill -9 <pid> 
pkill -u <uid> -f "<process_name>"

• Terminal Multiplexer
  • Zellij: an alternative to tmux and screen. An amazing feature is that you can use SCROLL MOUSE directly in a session.

bash <(curl -L zellij.dev/launch)

Disk Management

• Show volume per folder (depth=1)

$ du -h -d 1 /scratch/users/sx233/
404M    /scratch/users/sx233/6980-sp23
4.5G    /scratch/users/sx233/conda

• Show mounting FS of target folder and FS capcity

>> df -h --block-size=GB /scratch/users/
Filesystem               1GB-blocks   Used Available Use% Mounted on
