I'm embarrassed! I went back and discovered I tested only against the line with PORT and not the whole file. Grrr!!

The awk itkamaraj posted is much cleaner, but it can be done in sed:

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

by combining 2 commands it's giving the output :
tnsping abc | sed 's/.*\(PORT =\)/\1/; s/).*//' | nawk -F"=" '/PORT/ {print $2}'


this the value of port ( and this is what I want)

is there way to combine these two ?

Does this not work by itself?

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

I noticed you had my old, and very wrong, original post. This is the one that I believe should do the trick.

I also see that itkamaraj's awk works only on the output of my bad command, not on the output of your command. Didn't catch that before.

And if that sed doesn't work (I have a version of sed that doesn't like that syntax), here's an awk that should work in every environment:

tnsping abc | awk '/PORT =/ { gsub( ".*PORT =", "" ); gsub( ").*", "" ); print; }'

awk '/PORT =/ { gsub( ".*PORT =", "" ); gsub( ").*", "" ); print; }'

this is not working on Solaris . Is this because of gsub ?

Yes. Use nawk or /usr/xpg4/bin/awk on Solaris.
