script check the users in SHELL every 1 minute ?
could you please find a solution for this:
I need to write a shell script which checks after every minute whether a friend has logged in or not.The script should report whether that person has logged in along with the amount of time the person was late in logging in.
I have no idea how to do this bcoz i'm really new to it,and it would be really nice if someone could help

ruptime
ruptime(1) General Commands Manual ruptime(1) NAME
ruptime - show status of local machines SYNOPSIS
DESCRIPTION
outputs a status line for each machine on the local network that is running the daemon. status lines are formed from packets broadcast once every 3 minutes between daemons (see rwhod(1M)) on each host on the network. Each status line has a field for the name of the machine, the status of the machine (up or down), how long the machine has been up or down, the number of users logged into the machine, and the 1-, 5- and 15-minute load averages for the machine when the packet was sent. The status of the machine is reported as ``up'' unless no report has been received from the machine for 11 minutes or more. The length of time that the machine has been up is shown as: Load averages are the average number of jobs in the run queue over the last 1-, 5- and 15-minute intervals when the packet was sent. An example status line output by might be: The above status line would be interpreted as follows: is presently ``up'' and has been up for 1 day, 5 hours and 15 minutes. It currently has 7 users logged in. Over the last 1-minute inter- val, an average of 1.47 jobs were in the run queue. Over the last 5-minute interval, an average of 1.16 jobs were in the run queue. Over the last 15-minute interval, an average of 0.80 jobs were in the run queue. If a user has not used the system for an hour or more, the user is considered idle. Idle users are not shown unless the option is speci- fied. Options If no options are specified, the listing is sorted by host name. Options change sorting order as follows: Sort by load average. Sort by up time. Sort by the number of users. Reverse the sort order. DIAGNOSTICS
No status report files in Ask the system administrator to check whether the daemon is running. AUTHOR
