Hello, I am (trying) to write a script that will check to see how many users are logged on to my machine, and if that number is more than 60 I need to kill off all the oldest sessions that are over 60. So far I have been able to check how many users are on and now I am at the part where I have to actually kill them off. I have chosen to write the idle times for all the logged on users into a file, but I need to add leading zeroes to them in order to properly sort them. How do I do this? the file is /tmp/uidle. This is my code so far:
Code:
numusers=$(who -q | grep Total | tr -s " " | cut -d" " -f3)
echo Total number of users: ${numusers}
if test $numusers -gt 60; then
diff=$(expr $numusers - 60)
echo "There are $diff too many users, killing the $diff oldest users..."
who -u | sort -k4.2,6 | grep bhb | tr -s " " | cut -d" " -f5 >> /tmp/uidle
else
echo "There are less than 60 users. Exiting"
fi
exit 1
How do I trim the leading zeroes, and (+,-) in the currency field ?

Hi,
I need add leading zeroes to a field in a file based on the character count. The field can be of 1 character to 6 character length. I need to make the field 14bytes.
eg:
8351,20,1
8351,234,6
8351,2,0
8351,1234,2
8351,123456,1

This should become.

rusers
rusers(1) User Commands rusers(1)NAME
rusers - who is logged in on remote machines
SYNOPSIS
rusers [-ahilu] host...
DESCRIPTION
The rusers command produces output similar to who(1), but for remote machines. The listing is in the order that responses are received, but
this order can be changed by specifying one of the options listed below.
The default is to print out the names of the users logged in. When the -l flag is given, additional information is printed for each user:
userid hostname:terminal login_date login_time idle_time login_host
If hostname and login host are the same value, the login_host field is not displayed. Likewise, if hostname is not idle, the idle_time is
not displayed.
A remote host will only respond if it is running the rusersd daemon, which may be started up from inetd(1M) or listen(1M).
In the absence of a name service, such as LDAP or NIS, rusers displays host names as numeric IP addresses.
OPTIONS -a Give a report for a machine even if no users are logged on.
-h Sort alphabetically by host name.
-i Sort by idle time.
-l Give a longer listing in the style of who(1).
-u Sort by number of users.
