No need to write a script, just use last command.

Yes , you are right.
But want to generate an email with information which has been written in the last command. Please see the script below this emails be when user login in. Code:
#!/bin/bash
l=`last -n 5 | awk "NR==1" | awk -F " " '{print $1, $3, $4, $5, $6, $7}'`
ip=`last -n 5 | awk "NR==1" | awk -F " " '{print $3}'`
h=`echo $HOSTNAME`
/usr/local/bin/sendEmail -t example@example.com -f example@example.com -s smtp.example.com -m $l -u Login to $h by $ip

Dear lim,
Code:
#!/bin/bash
l=`last -n 5 | awk "NR==1" | awk -F " " '{print $1, $3, $4, $5, $6, $7}'`
ip=`last -n 5 | awk "NR==1" | awk -F " " '{print $3}'`
h=`echo $HOSTNAME`
/usr/local/bin/sendEmail -t example@example.com -f example@example.com -s smtp.example.com -m $l -u Login to $h by $ip
When a user logged in session will be recorded like this Code:
root pts/1 xxx.xxx.xxx.xxx Tue Jun 9 02:00 still logged in When a user logged out the last shows output like this: Code:
root pts/2 xxx.xxx.xxx.xxx Tue May 19 04:36 - 05:29 (00:52) awk "NR==1" | awk -F " " '{print $1, $3, $4, $5, $6, $7, $8, $9, $10}' is also fail, this will only print the very first line. So i want a command/script which search in last command and print the output of certain session. Any help please
