This command is used to execute an SQL file in psql (PostgreSQL command-line tool) by specifying the database name and the file path.
Here's a breakdown of the command syntax:
-
psql: This is the command to start the psql tool. -
${database}: This is a placeholder for the actual name of the database you want to connect to. It should be replaced with the actual database name. -
-f: This flag is used to specify that an SQL file will be executed. -
${file-sql}: This is a placeholder for the actual file path of the SQL file you want to execute. It should be replaced with the actual file path, including the file name and extension.
By running this command, psql will connect to the specified database and execute the SQL statements in the given file.
