Unix script that checks each minute and reports on who logs in and who logs out?
You can create a Unix script that checks for user logins and logouts by monitoring the /var/log/auth.log or /var/log/secure file, depending on your Unix distribution. Use the last command to list users who have logged in, and last -x to include system shutdowns and runlevel changes, which indicate logouts. Schedule the script to run every minute using a cron job with the command * * * * * /path/to/your/script.sh. Ensure the script captures the output and reports the findings, perhaps by appending the results to a log file.
