I think the first line skips over the tnsnames.ora until it finds a pattern 'variable ='. So this will give us the left hand side in $1?
The second line searches for the SERVICE_NAME entry, where the value matches s, which is set on the command line to be 'pri'.
You store this in $1 ....but didn't we keep the left hand side there?
... I do not understand the third line at all.
I forgot that
( is special in ERE, that awk uses. You found it: needs to be escaped. An alternative would be
[(].
Each code line is a
condition { action }.
All three code lines are run for each input line.
If the condition in the 2nd code line is true it performs the action: print variable
a.
This is set in the 3rd code line to field#1, if it does not have a
( at the beginning.

sge_hostnameutils
HOSTNAMEUTILS(1) Sun Grid Engine User Commands HOSTNAMEUTILS(1)
NAME
sge_hostnameutils.1 - SGE Host name utilities
gethostname -
get local hostname.
gethostbyname -
get local host information for specified hostname.
gethostbyaddr -
get hostname via IP address.
getservbyname -
get configured port number of service
SYNTAX
gethostname [-help|-name|-aname|-all]
gethostbyname [-help|-name|-aname|-all] <name>
gethostbyaddr [-help|-name|-aname|-all] <ip>
getservbyname [-help|-number] <service>
DESCRIPTION
gethostname and gethostbyname are used to get the local resolved host name. gethostbyaddr is used to get the hostname of a specified IP
address (dotted decimal notation). getservbyname can be used to get the configured port number of a service (e.g. from /etc/services).
The hostname utils are primarily used by the Sun Grid Engine installation scripts. gethostname , gethostbyname and gethostbyaddr called
without any option will print out the hostname, all specified aliases, and the IP address of the locally resolved hostname. Calling get-
servbyname without any option will print out the full service entry.
OPTIONS
-help
Prints a list of all options.
-name
This option only reports the primary name of the host.
-aname
If this option is set, the Sun Grid Engine host alias file is used for host name resolving. It is necessary to set the environment variable
SGE_ROOT and, if more than one cell is defined, also SGE_CELL.
This option will print out the Sun Grid Engine host name.
-all
By using the -all option all available host information will be printed. This information includes the host name, the Sun Grid Engine host
name, all host aliases, and the IP address of the host.
-number
This option will print out the port number of the specified service name.
<name>
The host name for which the information is requested.
<ip>
The IP address (dotted decimal notation) for which the information is requested.
<service>
The service name for which the information is requested (e.g. ftp, sge_qmaster or sge_execd).
EXAMPLES
The following example shows how to get the port number of the FTP service:
>getservbyname -number ftp
21
The next example shows the output of gethostname -all when the host alias file contains this line:
gridmaster extern_name extern_name.mydomain
The local host resolving must also provide the alias name "gridmaster". Each Sun Grid Engine host that wants to use the cluster must be
able to resolve the host name "gridmaster".
To setup an alias name, edit your /etc/hosts file or modify your NIS setup to provide the alias for the NIS clients.
The host alias file must be readable from each host (use e.g. NFS shared file location).
>gethostname -all
Hostname: extern_name.mydomain
SGE name: gridmaster
Aliases: loghost gridmaster
Host Address(es): 192.168.143.99
ENVIRONMENTAL VARIABLES
SGE_ROOT Specifies the location of the Sun Grid Engine standard configuration files.
SGE_CELL If set, specifies the default Sun Grid Engine cell.
