ksh help
Hi,

I have command like this with ooutput :

Code:
unix>tnsping abc

Code:
TNS Ping Utility for IBM/AIX RISC System/6000: Version 10.2.0.4.0 - Production on 17-AUG-2011 17:06:11

Copyright (c) 1997,  2007, Oracle.  All rights reserved.

Used parameter files:
/opt/oracle/network/admin/sqlnet.ora


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = key))) (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = host.domain)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = instance_name) (INSTANCE_NAME = instance_name)))
OK (20 msec)

I want to parse it to get port number ..

e.g. tnsping abc | grep PORT =

any help ...

Thanks

I'd probably use sed.

Code:
command | sed 's/.*PORT =/PORT =/; T del; s/).*//; t; :del d'

Code:
grep -Po '(?<=PORT = )\d+'

Thanks

What was the output that was produced, or the errors generated? Both work for me on Linux.

The output has multiple lines . need just value of port ( in this case 2100) .
Appreciate your help.

Thanks
