+# Schedule an update of the Microsoft Defender for Endpoint (Linux)
+
+To run an update on Microsoft Defender for Endpoint for Linux, see [Deploy updates for Microsoft Defender for Endpoint for Linux](https://docs.microsoft.com/windows/security/threat-protection/microsoft-defender-atp/linux-updates).
+
+Linux (and Unix) have a tool called **crontab** (similar to Task Scheduler) to be able to run scheduled tasks.
+
+## Pre-requisite
+
+> [!NOTE]
+> To get a list of all the time zones, run the following command:
+> `timedatectl list-timezones`<br>
+> Examples for timezones: <br>
+> - `America/Los_Angeles`
+> - `America/New_York`
+> - `America/Chicago`
+> - `America/Denver`
+
+## To set the Cron job
+Use the following commands:
+
+**To backup crontab entries**
+
+`sudo crontab -l > /var/tmp/cron_backup_201118.dat`
+
+> [!NOTE]
+> Where 201118 == YYMMDD
+
+> [!TIP]
+> Do this before you edit or remove. <br>
+
+To edit the crontab, and add a new job as a root user: <br>
+`sudo crontab -e`
+
+> [!NOTE]
+> The default editor is VIM.
+
+You might see:
+
+0****/etc/opt/microsoft/mdatp/logrorate.sh
+
+And
+
+02**sat /bin/mdatp scan quick>~/mdatp_cron_job.log
+
+See [Schedule scans with Microsoft Defender for Endpoint (Linux)](linux-schedule-scan-atp.md)
+
+Press “Insert”
+
+Add the following entries:
+
+CRON_TZ=America/Los_Angeles
+
+> #!RHEL and variants (CentOS and Oracle Linux)
+
+`06**sun[$(date +\%d) -le 15] sudo yum update mdatp>>~/mdatp_cron_job.log`
+
+> #!SLES and variants
+
+`06**sun[$(date +\%d) -le 15] sudo zypper update mdatp>>~/mdatp_cron_job.log`
+
+> #!Ubuntu and Debian systems
+
+`06**sun [$(date +\%d) -le 15] sudo apt-get install --only-upgrade mdatp>>~/mdatp_cron_job.log`
+
+> [!NOTE]
+> In the examples above, we are setting it to 00 minutes, 6 a.m.(hour in 24 hour format), any day of the month, any month, on Sundays.[$(date +\%d) -le 15] == Won’t run unless it’s equal or less than the 15th day (3rd week). Meaning it will run every 3rd Sundays(7) of the month at 6:00 a.m. Pacific (UTC -8).
+
+Press “Esc”
+
+Type “:wq” w/o the double quotes.
+
+> [!NOTE]
+> w == write, q == quit
+
+To view your cron jobs, type `sudo crontab -l`
+
+:::image type="content" source="images/update-MDE-linux-4634577.jpg" alt-text="update MDE linux":::
+
+To inspect cron job runs:
+`sudo grep mdatp /var/log/cron`
+
+To inspect the mdatp_cron_job.log
+`sudo nano mdatp_cron_job.log`
+
+## For those who use Ansible, Chef, or Puppet
+
+Use the following commands:
+### To set cron jobs in Ansible
+
