UNIX for Dummies Questions & Answers

Code:

finger $LOGNAME | grep -A1 $a | tail -1

sorry i am not getting how your command will work , its not a complet one

The output of finger $LOGNAME from my system doesn't appear to be in the same format as yours.
This is how I get it, in a single line:

Code:

$ a=`tty | sed 's_/dev/__'`; finger $LOGNAME | grep $a
On since Mon Dec 26 05:47 (GMT) on pts/2 from xxx.xxx.xx.xx

So, please post the exact output from your system

Code:

a=`tty | sed 's_/dev/__'`; finger $LOGNAME | grep -A1 $a | tail -1

And please use code tags.

Please reveal what Operating System and version you have and what Shell you are using.

On your previous threads we never understood how this connection works.
https://www.unix.com/shell-programmin...inal-unix.html

If these connections show as pts connections then the output from the "last" command would be easier to work with than "finger".

Code:

last -R -20 ${LOGNAME} | grep "still logged in"

(The exact syntax of "last" will depend on your Operating System).


If this is connecting to a database engine this sort of information would normally be available to the database engine.

I will give more details on this

Code:

 
finger $LOGNAME

output
--------
Login name: ab67999 In real life: felisaona
Site Info: abc,zxccb,100089
Directory: /home/ab67999 Shell: /bin/ksh
On since Jan 30 02:03:20 on pts/2
from psxjj10067.emea.nsoot.net
On since Jan 30 02:04:31 on pts/3, 13 seconds Idle Time
from psxjj90067.emea.nsoot.net
No Plan.

and output for below stuff

Code:

a=`tty | sed 's_/dev/__'`; finger $LOGNAME | grep $a

output
On since Jan 30 02:03:20 on pts/2

as you can see id ab67999 logged in from 2 different machine psxjj10067.emea.nsoot.net & psxjj90067.emea.nsoot.net and hence by getting pts from second command we conclude that psxjj10067.emea.nsoot.net is the current machine console and I want to extract that ..

I was able to extract using below command , but I feel its too long . Please let me know if there is efficient way that anyone can think of
I have give out put as well for each variable (shell is ksh and uname - a has output as follows "AIX mdddddd01u 1 6 00JKM1223C00")
Note that I am exexuting this query from an application and hence command who,tty cannot be used

Code:

a=`ps | grep "ksh" | tail -1 | cut -f4 -d' '`;b=`finger $LOGNAME | grep $a`;c=`finger $LOGNAME` ;d=`echo $c | awk '{gsub(/On/,"\nOn");print}' | grep "$b" | cut -f9 -d' ' | tail -1`;echo $LOGNAME@$d

output
