erl:tldr:6ac52
This command is used to initiate a remote shell connection to a Erlang node running on a different host (or the same host if desired).
Here is a breakdown of the command and its options:
-
erl
: This is the Erlang runtime command. It is used to start the Erlang system. -
-remsh {nodename}@{hostname}
: This option specifies the remote node with which you want to establish a shell connection.{nodename}
is the name of the remote node, and{hostname}
is the hostname or IP address of the remote machine. -
-sname {custom_shortname}
: This option allows you to specify a custom short name for the local node.{custom_shortname}
is the desired short name for the local node. -
-hidden
: This option makes the local node hidden and does not advertise it to other nodes on the network. -
-setcookie {cookie_of_remote_node}
: This option sets the authentication cookie for the remote node.{cookie_of_remote_node}
is the cookie value of the remote node, which must match for successful communication.
Overall, this command connects to a remote Erlang node using a specified node name and hostname, sets a custom short name for the local node, hides the local node from other nodes, and authenticates with the remote node using a cookie.
