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???

PTS_QUIT(1)						       AFS Command Reference						       PTS_QUIT(1)

NAME
pts_quit - Exit from pts interactive mode SYNOPSIS
pts quit [-cell] <cell name> [-noauth] [-localauth] [-force] pts q [-c] <cell name> [-n] [-l] [-f] DESCRIPTION
The pts quit command exits from pts interactive mode. The command can be run from the command line or interactively, but on the command line it does nothing and is therefore of questionable utility. CAUTIONS
Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts quit command was only available on Unix or Linux and when OpenAFS was compiled with the supergroups option (disabled by default). As of OpenAFS 1.4.5 and 1.5.23, it is always available. OPTIONS
Although they have no effect, pts quit takes the following standard pts options: -cell <cell name> Names the cell in which to run the command. For more details, see pts(1). -force Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the first error. -help Prints the online help for this command. All other valid options are ignored. -localauth Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or -noauth options. For more details, see pts(1). -noauth Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1). OUTPUT
This command produces no output. EXAMPLES
Here is an example of a pts interactive session: % pts interactive pts> quit % SEE ALSO
