user on

ladytwo · #1 (**permalink**) 10-03-2007

I am writing a script and i want to see if this user is on and when they log off. i have some of what i want but not sure if it is right. i think it is just pulling a name from file.

while true
do
if who | grep someone "file"
then break
done

what am I doing wrong?
Please help!

You want the last command"

Code:

last -1 jmcnama
jmcnama  pts/7        Wed Oct  3 08:24   still logged in

You will see "still logged in" if the user (in this case: jmcnama) is still logged on
the -1 is a dash <character 1>

No i want to know if a person has logged in and when they log out.

That is what the last command is meant for. It reads the /var/adm/wmtp (or wtmps) file.

If you explain exactly what you want - like an alarm or something - maybe we can help.

maybe:

Code:

#!/bin/ksh
while true
do
	last -1 <username> | read record
	echo "$record" | grep -q 'still logged'
	if [[ $? -eq 0 ]]; then
	   print " <username> is still logged in "
	else   
	   print $record
	   break
	fi
	sleep 5
done
