- Execute a Julia program that takes arguments:

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

- Evaluate a string containing Julia code:

`julia -e '{{julia_code}}'`

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

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

- Evaluate an expression and print the result:

`julia -E '{{(1 - cos(pi/4))/2}}'`

- Start Julia in parallel mode, using N worker processes:

`julia -p {{N}}`
