man bash and search for command substitution.

Quote:

Command Substitution
Command substitution allows the output of a command to be substituted in place of the command name itself. Command substitution occurs when the command is enclosed as follows:
$(command)
or (“backquoted” version):
`command`
.

.

It's been around in sh already, so it MUST be there. What shell and version do you use?

drop_text_search_template

DROP TEXT SEARCH 
TEMPLATE(7)				  PostgreSQL 9.2.7 Documentation			      DROP TEXT SEARCH TEMPLATE(7)

NAME

       DROP_TEXT_SEARCH_TEMPLATE - remove a text search template

SYNOPSIS

       DROP TEXT SEARCH TEMPLATE [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TEXT SEARCH TEMPLATE drops an existing text search template. You must be a superuser to use this command.

PARAMETERS

       IF EXISTS
	   Do not throw an error if the text search template does not exist. A notice is issued in this case.

       name
	   The name (optionally schema-qualified) of an existing text search template.

       CASCADE
	   Automatically drop objects that depend on the text search template.

       RESTRICT
	   Refuse to drop the text search template if any objects depend on it. This is the default.

EXAMPLES

       Remove the text search template thesaurus:

	   DROP TEXT SEARCH TEMPLATE thesaurus;

       This command will not succeed if there are any existing text search dictionaries that use the template. Add CASCADE to drop such
       dictionaries along with the template.

COMPATIBILITY

       There is no DROP TEXT SEARCH TEMPLATE statement in the SQL standard.
