sql file in sqlplus

hello fellas, today i'm sharing my learning how to run sql file from sqlplus,
create a sql file lets suppose test.sql
and put some code like select query from a pre-defined or custom table from hr schema,

select * from country;

save and close it.
 save it anywhere on hard-drive like i've saved it directly on c drive;

open cmd connect it and enter the cmd like

@/test.sql

 simply put this @/ before the path of the sql file.
and cmd will execute

 

thank you :)
