UNIX for Dummies Questions & Answers

Hi,

I am writing script to take last logon user id detials by using finger command.

But I am getting below output.

wer34 Feb 10:23

I NEED to display

wer34 Feb 10 2013 10:23, Is there any way to get like this.

As with ls -l, login time in finger output is month, day, and time if the login time is within six months of the current time; otherwise it is month, day, and year. So, if the year or time field contains a colon, you can figure out if the month and day shown are in the current year or the previous year an add it as needed. But, if the login time was more than 6 months ago, there is no way to get the login time unless your version of finger provides an option that allows you to override the default login time output format.

Thanks Don.

I want to write report for last logon user detials.

Code:

The below user id wre34 is not an active user from Sep 2013. his last logon Aug 7 2013
 
Directory: /export/home/wre34           Shell: /bin/ksh
Last login Wed Aug  7, 2013 on pts/111
No unread mail
No Plan.
 
The other user id ivv41 las logon was Sep 21 2013
 
Directory: /export/home/ivv41           Shell: /bin/ksh
Last login Mon Sep 23 17:28 on pts/47 from remb02mkiwsf25
Mail last read Sat Sep 21 15:13:31 2013
No Plan
 
current usr id
 
Directory: /export/home/por12           Shell: /bin/ksh
On since Feb 17 15:26:40 on pts/75 
Mail last read Sat Feb  1 15:25:28 2014
No Plan.

If I use finger userid |grep On Since

I would get month date time and year but login time was more than 6 months ago will not display.

Moderator's Comments:

Please use CODE tags to mark sample input, sample output, and sample code. I have added CODE and ICODE tags to this post, but I am not at all sure that I put the CODE tags in the right spots. (I don't know if there should be one sample output or three sample outputs.

If you use finger userid |grep On Since you're likely to get a diagnostic message like:

Code:

grep: Since: No such file or directory

And since your output shows that the output from the lines you're trying to match doesn't have Since capitalized, even if you had quoted it correctly you still wouldn't get any output. Perhaps you meant:

Code:

finger <userid> | grep 'On since'

which could give you several lines of output for the specified user.

If someone's last login time was more than six months ago, why does it matter what time of day it was for a report like this?

For someone still logged in, unless you are keeping systems up for more than a year and a half without rebooting, the year should be obvious as long as the date the report was generated is included in the report.

But I have requirment like the active user list last logon detials report, at lease need date,month and year

So what have you tried to do to convert the time stamp into a year for login times that occur in the last six months?

To get year thought of using

Code:

Last

command but it is taking from /wtmp directory. Also this folder get created every month on 1st date. So If I run last command it shows from Feb 1st 2014.

But I want all active user last logon detials with year


Example - If user logged on Dec 12 2013. If I run report today I wanna get O/P like
