Programs like login, shutdown, uptime and others want to read from and write to the /var/run/utmp /var/log/btmp and /var/log/wtmp. These files contain information about who is currently logged in. It also contains information on when the computer was last booted and shutdown and a record of the bad login attempts. Create these files with their proper permissions by running the following commands: touch /var/run/utmp /var/log/wtmp \     /var/log/btmp /var/log/lastlog && chmod 644 /var/run/utmp /var/log/wtmp \    /var/log/btmp /var/log/lastlog
