I want to type only the filename of a gcc source that has ".syn" as an extension and copy it, changing the extension to ".c" so it can be compiled.
I do it as follows:
This works fine, but if I want to repeat the compilation by recovering the previous call using history, the full filename plus the extension ".syn" appears and I have to delete the ".syn" to use my script.
Because so many programs give one an option of typing a filename with or without an ext, there must be a simple way to do this. How is it done?

drop_extension
DROP EXTENSION(7) PostgreSQL 9.2.7 Documentation DROP EXTENSION(7)NAME
DROP_EXTENSION - remove an extension
SYNOPSIS
DROP EXTENSION [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP EXTENSION removes extensions from the database. Dropping an extension causes its component objects to be dropped as well.
You must own the extension to use DROP EXTENSION.
PARAMETERS
IF EXISTS
Do not throw an error if the extension does not exist. A notice is issued in this case.
name
The name of an installed extension.
CASCADE
Automatically drop objects that depend on the extension.
RESTRICT
Refuse to drop the extension if any objects depend on it (other than its own member objects and other extensions listed in the same
DROP command). This is the default.
EXAMPLES
To remove the extension hstore from the current database:
DROP EXTENSION hstore;
This command will fail if any of hstore's objects are in use in the database, for example if any tables have columns of the hstore type.
Add the CASCADE option to forcibly remove those dependent objects as well.
COMPATIBILITY
DROP EXTENSION is a PostgreSQL extension.
