Last command does not show year in HP-UX

[Bharat Walunj]

Hi,

Please let me know if their is any script to generate the year with last command.
$ last oracle|more
oracle pts/1 Mon Aug 27 15:49 - 17:55 (02:06)


For solaris we have as

last | nawk 'BEGIN {y='`date +%Y`'}$5 == "Dec" && last != "Dec" { y-- }{ print y,$0 ; last = $5 }' |more

But nawk does not work in HP.

Hi Bharat,

last command will not display year. But you can use fwtmp to extract out the year.

To read the contents of the wtmp file, cat the file to fwtmp, as follows:

#cat /var/adm/wtmp | /usr/sbin/acct/fwtmp

WK

please assign points

Shalom,

You let users remain logged on the system constantly from year to year?

As the thread shows, the information certainly does exist, however the reason HP didn't include it may be the basic assumption that everybody knows what year it is.

Even 24/7 systems should be brought down twice a year for critical bi-annual and security patches, making the need to display the year, somewhat superflous?

Good Luck,

Hi In HP nawk is not working you have to try with awk only

>For Solaris we have as ...

Ah, I didn't look at the script. I thought of writing something like this for the other thread but using fwtmp seemed better.

Your awk script has several flaws. You need to look at $4 and sometimes $5 (if you rebooted in Dec). Also `` doesn't work within '', so you need to use -v:
last | awk -v y=$(date +%Y) '
{
if ($2 == "system" && $3 == "boot") month = $5
else month = $4
if (month == "Dec" && last != "Dec") y--
print y,$0
last = month
}'

Hi,

besides the correct approach to use 'fwtmp', I see no problem in this awk-statement regarding backticks:
awk 'BEGIN {y='`date +%Y`'} ...'

Having spliced in the `..` into two parts of single quoted strings AND `date +%Y` not producing any spaces in output, the finally string the shell leaves as commands for the awk is only one argument and so perfectly OK.

Ah, you are correct but nobody in their right mind should use that. The whole awk script should be single quoted, not pieced together like Humpty-Dumpty. Also, this wouldn't work for awk -f.

Here is another thread about awk -v:
