- Start a REPL (interactive shell):

`julia`

- Execute a Julia program and exit:

`julia {{program.jl}}`

- Execute a Julia program that takes arguments:

`julia {{program.jl}} {{arguments}}`

- Evaluate a string containing Julia code:

`julia {{[-e|--eval]}} '{{julia_code}}'`

- Evaluate a string of Julia code, passing arguments to it:

`julia {{[-e|--eval]}} '{{for x in ARGS; println(x); end}}' {{arguments}}`

- Evaluate an expression and print the result:

`julia {{[-E|--print]}} '{{(1 - cos(pi/4))/2}}'`

- Start Julia in multithreaded mode, using `n` threads:

`julia {{[-t|--threads]}} {{n}}`
