| Dears,
Greetings to Unix/solaris Users..
I want one script to kill the login more than 60minities idle.
Example :
# who -u
gatepass pts/22 Oct 19 11:39 . 22216 (192.9.200.31)
root console Oct 9 18:47 0:25 639 (:0)
stores pts/4 Oct 19 08:43 2:02 19567 (192.9.200.31)
fas pts/2 Oct 19 10:11 0:04 20451 (192.9.200.21)
sis pts/5 Oct 19 08:24 . 19495 (192.9.200.12)
sis pts/25 Oct 19 11:47 0:37 22550 (192.9.200.16)
sis pts/7 Oct 19 08:36 0:08 19556 (192.9.200.11)
stores pts/8 Oct 19 08:44 0:03 19581 (192.9.200.31)
stores pts/11 Oct 19 08:44 2:00 19595 (192.9.200.31)
gatepass pts/12 Oct 19 08:44 1:33 19611 (192.9.200.31)
pur pts/13 Oct 19 08:58 1:33 19643 (192.9.200.31)
ccc pts/14 Oct 19 09:16 1:39 19774 (192.9.200.122)
stores pts/15 Oct 19 08:58 1:03 19668 (192.9.200.33)
sis pts/21 Oct 19 10:32 1:45 20927 (192.9.200.12)
ccc pts/28 Oct 19 11:50 . 22592 (192.9.200.81)
sis pts/20 Oct 19 09:28 3:00 19874 (192.9.200.11)
mms pts/18 Oct 19 11:07 1:51 21569 (192.9.200.64)
stores pts/27 Oct 19 10:18 2:52 20643 (192.9.200.33)
aps pts/32 Oct 19 12:25 . 23172 (192.9.200.24)

root pts/6 Oct 19 11:44 0:25 22495 (:0.0)
#
in the above example i want more than one hour idle..such as...
gatepass pts/12 Oct 19 08:44 1:33 19611 (192.9.200.31)
pur pts/13 Oct 19 08:58 1:33 19643 (192.9.200.31)
ccc pts/14 Oct 19 09:16 1:39 19774 (192.9.200.122)
stores pts/15 Oct 19 08:58 1:03 19668 (192.9.200.33)
sis pts/21 Oct 19 10:32 1:45 20927 (192.9.200.12)
stores pts/27 Oct 19 10:18 2:52 20643 (192.9.200.33)
Please give the script to me..

Alternately you could look at idled

First, you are executing it with sh; that's a Bourne shell, I believe, on
Solaris. Don't use "sh ksh93", use:
../ksh93
Whatever sh is, it doesn't recognize '--' as meaning an end to
options. There's no point to it, anyway, as UNAME is a constant
not a variable. It would be a good idea (though it's not the cause
of your problem) to change the name to something that doesn't
collide with an executable in your path.
Second, the versions of ksh93 I have (Version M 1993-12-28 {m+,n})
do not recognize ">=" as an operator:
ksh: line 3: 00 \>= 1 : arithmetic syntax error
Use -ge instead.
Third, why not use a syntax that will work in all Bourne-type
shells as well as in ksh:
[ ${IDLE%%:*} -ge 1 ] && kill ${PID}
Fourth, I don't have a Solaris box here to check (and the output
of "who -u" differs from one OS to another), but are you sure that
${IDLE%%:*} will return a valid number?
Fifth, you will save yourself a lot of grief by using a case
statement; then it doesn't matter if $IDLE is not a number:
who -u | while read UNAME TTYNUM MON DOM TIME IDLE PID ADDR
do
case $IDLE in
[0-9][0-9]:*) echo $PID ;; ## check it first ## kill ${PID} ;;
esac
done

Unclear what you mean by UNAME is a constant not a variable. If UNAME
is
set as a read-only variable on your system, then it is specific to
your
system and is non-standard.

Thats odd, I am running the ATT binary version "Version M 1993-12-28
p" and it is recognized. I also tested it with the IBM implementation
of ksh93 "Version M-12/28/93e" and it works correctly. Regardless the
"-ge" operator is obsolete and should not be used.

Because the point of me participating in this newsgroup is to provide

I based the solution on the data provided by the OP, if the OP
provided valid data, it should provide a valid number.

That will certainly work, however the pattern you suggested will not,
The pattern needs to change to match any single or double digit number
equal to or greater than 1.
So I'll throw the ball back to you, in Korn/Bourne shell syntax,
represent a single or double digit number equal to or greater than 1.
Recognize that the pattern will need to recognize the numbers 0 and
10, and distinguish between them.

I think I figured out the problem there, the statement was:
(( ${IDLE%%:*} >= 1 )) && kill ${PID}
The "who -u" as represented by the OP will display a dot "." for the
current logins instead of the idle time. In the latest versions of
ksh93, a math statement will accept a dot "." on the left side of the
equation, earlier versions will not. So the statement should change
as follows:
(( ${IDLE//@(.|:*)/.0} >= 1 )) && kill ${PID}
This will substitute a dot or everything after the colon with a ".0"
and the math comparison should work correctly. The problem was not
the ">=" operator, rather it was the dot on the left side of the
comparison.

I believe Chris is talking about the difference between these:
read UNAME
read "$varname"
In the first case, it's immediately obvious that there's no danger of
the variable name being interpreted as an option, so there's no need
to protect it with --.

In this case, it's easy to make the solution work in other shells as
well, without losing anything.

Asssuming there will not be leading zeros:
case $num in
[2-9]|[1-9][0-9]*) echo greater than 1;;
*) echo not greater than 1 - possibly non-numeric;;
esac
