Check Login in Xubuntu

Add premission to file:

chmod +x check-login.sh

Move file check-login.sh:

mv check-login /usr/local/bin/

Create cron in system:

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
