If you want to assing values to variables (better: to elements of an array), you can do like that (in GNUlinux/bash):
Code:
$ FILES=( $(find /var/tmp -maxdepth 1 -type f -name "server_[0-9]*" -printf %f" ") )
$ declare -A NAMES    ###this opens an associative array
$ for SERVER in "${FILES[@]}"; do NAMES[$SERVER]=$(grep ssp "$SERVER"); done

If you want to print to screen the servers names, then:
Code:
$ for SERVER in "${FILES[@]}"; do echo -e "${SERVER} names are:\n${NAMES[$SERVER]}"; done

CREATE 
SERVER(7) PostgreSQL 9.2.7 Documentation CREATE SERVER(7) NAME
CREATE_SERVER - define a new foreign server SYNOPSIS
CREATE SERVER server_name [ TYPE 'server_type' ] [ VERSION 'server_version' ] FOREIGN DATA WRAPPER fdw_name [ OPTIONS ( option 'value' [, ... ] ) ] DESCRIPTION
CREATE SERVER defines a new foreign server. The user who defines the server becomes its owner. A foreign server typically encapsulates connection information that a foreign-data wrapper uses to access an external data resource. Additional user-specific connection information may be specified by means of user mappings. The server name must be unique within the database. Creating a server requires USAGE privilege on the foreign-data wrapper being used. PARAMETERS
server_name The name of the foreign server to be created. server_type Optional server type. server_version Optional server version. fdw_name The name of the foreign-data wrapper that manages the server. OPTIONS ( option 'value' [, ... ] ) This clause specifies the options for the server. The options typically define the connection details of the server, but the actual names and values are dependent on the server's foreign-data wrapper. NOTES
When using the dblink module (see dblink), the foreign server name can be used as an argument of the dblink_connect(3) function to indicate the connection parameters. See also there for more examples. It is necessary to have the USAGE privilege on the foreign server to be able to use it in this way. EXAMPLES
Create a server foo that uses the built-in foreign-data wrapper default: CREATE SERVER foo FOREIGN DATA WRAPPER "default"; Create a server myserver that uses the foreign-data wrapper pgsql: CREATE SERVER myserver FOREIGN DATA WRAPPER pgsql OPTIONS (host 'foo', dbname 'foodb', port '5432'); COMPATIBILITY
CREATE SERVER conforms to ISO/IEC 9075-9 (SQL/MED). SEE ALSO
ALTER SERVER (ALTER_SERVER(7)), DROP SERVER (DROP_SERVER(7)), CREATE FOREIGN DATA WRAPPER (CREATE_FOREIGN_DATA_WRAPPER(7)), CREATE USER MAPPING (CREATE_USER_MAPPING(7)) PostgreSQL 9.2.7 2014-02-17 CREATE SERVER(7)
