erl

TLDR

Compile and run sequential Erlang program as a common script and then exit

$ erlc [files] && erl -noshell '[mymodule:myfunction(arguments)], init:stop().'

Connect to a running Erlang node

$ erl -remsh [nodename]@[hostname] -sname [custom_shortname] -hidden -setcookie [cookie_of_remote_node]

Tell the Erlang shell to load modules from a directory

$ erl -pa [directory_with_beam_files]
