How can I execute a sql file for Oracle from a terminal?

I'm planning to run a SQL file which I expect would run for several hours, so I would like it to run in terminal on my dev server with tmux.  I suppose there should be some way sqlplus can accept a sql file as one of the predicates and execute the sql file.  Is my assumption correct?  If so, could you please provide me with the appropriate syntax?  Thanks.

navigate to the directory containing the sqlscript.sql

sqlplus user/password@database @sqlscript

if it runs for several hours, then i assume tuning is still possible

there is a few docs on how to use sqlplus

hit contents in the top left to learn all there is to know about sqlplus
you could run

>sqlplus username@DatabaseName

from command line tool and then enter a password when prompted, provided that Databasename is the entry that exists in tnsnames.ora file

then from SQL propmt run your file as:

SQL> start C:\Test\myfile.sql
