Let me add some more details to this ,
by command A)"finger $LOGNAME" I can get all session for the user as shown below
by command B)" a=`tty | sed 's_/dev/__'` ; finger $LOGNAME | grep $a " I can get my logged in terminal ,
but dont know how to extrat the next line "from <localhost>"

A)command prompt-> finger $LOGNAME
Login name: <loginname> In real life: <name>
Site Info: <sit info>
Directory: <homedir> Shell: /bin/ksh
On since Jan 27 01:37:28 on pts/0
from <localhost>
On since Jan 27 04:02:39 on pts/1, 4 minutes 19 seconds Idle Time
from <localhost>
No Plan.

B)command prompt-> a=`tty | sed 's_/dev/__'` ; finger $LOGNAME | grep $a
On since Jan 27 01:37:28 on pts/0

Moderator's Comments:

Please use next time code tags for your code and data

Code:

finger $LOGNAME | grep $a | awk '{print $(NF-1), $NF}'

this gets tty how we will get "from <machinename> which is on next line??

Please post the output of
finger $LOGNAME | grep $a. As there's no "next line" when I run this on my system.

When we run command "finger $LOGNAME" we get below details

Code:

command ->finger $LOGNAME
output -> Login name: abc In real life: lal
             Site Info: details
             Directory: <homedire-> Shell: <echo shell>
             On since Jan 27 06:36:07 on pts/0, 2 minutes 33 seconds Idle Time
             from <machine a>
             On since Jan 27 06:51:44 on pts/2
             from <machine b>
               On since Jan 27 06:45:19 on pts/7, 10 minutes Idle Time
               from <machine c>

we get 3 machines used to connect but to filter the current session I am using below stuff

Code:

Command -> a=`tty | sed 's_/dev/__'` ; finger $LOGNAME | grep $a
output -> On since Jan 27 06:36:07 on pts/0

But as you can see I need to extract "from <machine a>" from 1st command whcih is matching tty , how tthis can be done???
