1. Process related command

• top - real time view of all process running
• ps -aus - snapshot of all process running
• kill -9 PID - kill a process with PID as process id.
• nohup cmd > logs.out & - Run a process in background and deattach from terminal.
• screen - Start a screen terminal (-r restore, -ls view, Ctrl-A + d deattach screen)

2. Filesystem related

• ls -la - list all files in current directory
• **wc -l ** - Count number of lines in a file

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
