They Save You Time<\/h3>\n\n\n\n<p>Remember time? That thing you never have enough of? Cron jobs give it back. You set them, you forget them, and you&#8217;re pretty much never looking at them.<\/p>\n\n\n\n<p>(Well, until they break or you need to change the schedule.)<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. They Maintain Consistency<\/h3>\n\n\n\n<p>Humans are inconsistent. We forget things. We make typos. We get distracted by cat videos. Cron jobs perform the exact task, the exact same way, every single time \u2014 no exceptions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Your Server Never Sleeps<\/h3>\n\n\n\n<p>With cron jobs, essential maintenance happens 24\/7\/365, whether you&#8217;re awake, asleep, or on a beach sipping margaritas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Error Logs &gt; Human Memory<\/h3>\n\n\n\n<p>When you manually perform tasks, can you remember exactly what you did and exactly when you did it? Probably not.<\/p>\n\n\n\n<p>But cron jobs can be configured to log their activity, creating a paper trail of all automated actions for troubleshooting and verification.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. They\u2019re Built for Scalability<\/h3>\n\n\n\n<p>As your infrastructure grows, manually managing everything becomes exponentially more difficult. Cron jobs scale effortlessly.<\/p>\n\n\n\n<p>Meaning, the same job can run across multiple servers without requiring additional time from you.<\/p>\n\n\n\n<div class=\"article-newsletter article-newsletter--gradient\">\n\n\n<h2>Get Content Delivered Straight to Your Inbox<\/h2><p>Subscribe now to receive all the latest updates, delivered directly to your inbox.<\/p><form class=\"nwsl-form\" id=\"newsletter_block_\" novalidate><div class=\"messages\"><\/div><div class=\"form-group\"><label for=\"input_newsletter_block_\"><input type=\"email\"name=\"email\"id=\"input_newsletter_block_\"placeholder=\"Enter your email address\"novalidatedisabled=\"disabled\"\/><\/label><button type=\"submit\"class=\"btn btn--brand\"disabled=\"disabled\"><span>Sign Me Up!<\/span><svg width=\"21\" height=\"14\" viewBox=\"0 0 21 14\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n<path d=\"M13.8523 0.42524L12.9323 1.34521C12.7095 1.56801 12.7132 1.9304 12.9404 2.14865L16.7241 5.7823H0.5625C0.251859 5.7823 0 6.03416 0 6.3448V7.6573C0 7.96794 0.251859 8.2198 0.5625 8.2198H16.7241L12.9405 11.8535C12.7132 12.0717 12.7095 12.4341 12.9323 12.6569L13.8523 13.5769C14.072 13.7965 14.4281 13.7965 14.6478 13.5769L20.8259 7.39879C21.0456 7.17913 21.0456 6.82298 20.8259 6.60327L14.6477 0.42524C14.4281 0.205584 14.0719 0.205584 13.8523 0.42524Z\" fill=\"white\"\/>\n<\/svg>\n<\/button><\/div><\/form><\/div>\n\n\n<h2 id=\"h2_setting-up-cron-jobs-a-step-by-step-guide\" class=\"wp-block-heading\">Setting Up Cron Jobs: A Step-by-Step Guide<\/h2>\n\n\n\n<p>Enough theory!

But this section will take you a step further.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Using Special Strings<\/h3>\n\n\n\n<p>You don&#8217;t always need to write cron jobs with those asterisk signs. There are some special strings that let you set up cron jobs quite easily.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>@yearly or @annually: Run once a year (0 0 1 1 *)<\/li>\n\n\n\n<li>@monthly: Run once a month (0 0 1 * *)<\/li>\n\n\n\n<li>@weekly: Run once a week (0 0 * * 0)<\/li>\n\n\n\n<li>@daily or @midnight: Run once a day (0 0 * * *)<\/li>\n\n\n\n<li>@hourly: Run once an hour (0 * * * *)<\/li>\n\n\n\n<li>@reboot: Run once at startup<\/li>\n<\/ul>\n\n\n\n<p><strong>For example, if you want something to run daily, just write the below command:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>@daily \/path\/to\/daily-backup.sh<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Environment Variables in Crontab<\/h3>\n\n\n\n<p>To avoid repeating a string over and over again in your cron jobs (for example, a specific path, or your admin email), set up <a href=\"https:\/\/www.dreamhost.com\/blog\/environment-variables\/\">environment variables<\/a> at the beginning of your crontab.&nbsp;<\/p>\n\n\n\n<p>You can then reuse the variables as required within your scripts or commands.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>SHELL=\/bin\/bash\nPATH=\/usr\/local\/sbin:\/usr\/local\/bin:\/usr\/sbin:\/usr\/bin:\/sbin:\/bin\nMAILTO=admin@example.com\n\n# This job will send errors to admin@example.com\n0 2 * * * \/path\/to\/mailing_script.sh<\/code><\/pre>\n\n\n\n<p>If we use the environment variable <strong>MAILTO<\/strong> in our <strong>mailing_script.sh<\/strong>, the script will automatically send an email to the correct email address.<\/p>\n\n\n\n<p>With this, changing the admin email will only require changing the value of the MAILTO variable, instead of making changes across all scripts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Running Jobs As Different Users<\/h3>\n\n\n\n<p>If you have <a href=\"https:\/\/www.dreamhost.com\/blog\/wordpress-user-roles\/\">superuser access<\/a>, you can edit another user&#8217;s crontab:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo crontab -u username -e<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Using Anacron for Machines That Aren&#8217;t Always On<\/h3>\n\n\n\n<p>Unlike cron, anacron ensures jobs run even if the computer was off during the scheduled time:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo apt install anacron<\/code><\/pre>\n\n\n\n<p>Edit<strong> \/etc\/anacrontab<\/strong> to add jobs that will run when the system comes back online.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Job Chaining for Complex Workflows<\/h3>\n\n\n\n<p>Run jobs in sequence:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>0 1 * * * \/path\/to\/first-script.sh &amp;&amp; \/path\/to\/second-script.sh<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Monitoring Cron Jobs&nbsp;<\/h3>\n\n\n\n<p>For serious server management, consider tools like <a href=\"https:\/\/cronitor.io\/\">Cronitor<\/a> that provide monitoring and alerts for your cron jobs.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>0 * * * * cronitor exec check-12345 -- \/path\/to\/your\/script.sh<\/code><\/pre>\n\n\n\n<h2 id=\"h2_lets-talk-costs\" class=\"wp-block-heading\">Let\u2019s Talk Costs<\/h2>\n\n\n\n<p>Cron jobs can\u2019t exist in isolation. They need a server and a service running on a server that you need to manage.&nbsp;<\/p>\n\n\n\n<p>Now, if you\u2019re reading this article, it\u2019s highly likely that you have a server for your website or application.&nbsp;<\/p>\n\n\n\n<p>In fact, if you&#8217;re hosting with DreamHost VPS or any <a href=\"https:\/\/www.dreamhost.com\/glossary\/hosting\/linux-hosting\/\">Linux-based hosting provider<\/a>, you&#8217;ve already got everything you need to get started with automating your server management tasks.&nbsp;<\/p>\n\n\n\n<p>If not, a <a href=\"https:\/\/www.dreamhost.com\/hosting\/vps\/\">$10\/month VPS<\/a> is all you\u2019d need, especially when starting out.&nbsp;<\/p>\n\n\n\n<p>For those already running a DreamHost VPS, the process couldn&#8217;t be more straightforward:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>SSH into your server<\/li>\n\n\n\n<li>Run crontab -e to edit your personal cron table<\/li>\n\n\n\n<li>Add your scheduled tasks<\/li>\n\n\n\n<li>Save, and let the automation begin!<\/li>\n<\/ol>\n\n\n\n\n\n<div class=\"glossary-term\">\n\t<a\n\t\tclass=\"glossary-term__above-title\"\n\t\thref=\"\"\n\t\ttarget=\"_blank\"\n\t\trel=\"noopener noreferrer\"\n\t>\n\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 640 512\"><path d=\"M320 32c-8.1 0-16.1 1.4-23.7 4.1L15.8 137.4C6.3 140.9 0 149.9 0 160s6.3 19.1 15.8 22.6l57.9 20.9C57.3 229.3 48 259.8 48 291.9v28.1c0 28.4-10.8 57.7-22.3 80.8c-6.5 13-13.9 25.8-22.5 37.6C0 442.7-.9 448.3 .9 453.4s6 8.9 11.2 10.2l64 16c4.2 1.1 8.7 .3 12.4-2s6.3-6.1 7.1-10.4c8.6-42.8 4.3-81.2-2.1-108.7C90.3 344.3 86 329.8 80 316.5V291.9c0-30.2 10.2-58.7 27.9-81.5c12.9-15.5 29.6-28 49.2-35.7l157-61.7c8.2-3.2 17.5 .8 20.7 9s-.8 17.5-9 20.7l-157 61.7c-12.4 4.9-23.3 12.4-32.2 21.6l159.6 57.6c7.6 2.7 15.6 4.1 23.7 4.1s16.1-1.4 23.7-4.1L624.2 182.6c9.5-3.4 15.8-12.5 15.8-22.6s-6.3-19.1-15.8-22.6L343.7 36.1C336.1 33.4 328.1 32 320 32zM128 408c0 35.3 86 72 192 72s192-36.7 192-72L496.7 262.6 354.5 314c-11.1 4-22.8 6-34.5 6s-23.5-2-34.5-6L143.3 262.6 128 408z\"\/><\/svg>\n\t\t<span><\/span>\n\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 384 512\"><path d=\"M342.6 233.4c12.5 12.5 12.5 32.8 0 45.3l-192 192c-12.5 12.5-32.8 12.5-45.3 0s-12.5-32.8 0-45.3L274.7 256 105.4 86.6c-12.5-12.5-12.5-32.8 0-45.3s32.8-12.5 45.3 0l192 192z\"\/><\/svg>\n\t<\/a>\n    <h3>SSH<\/h3>\n    <p>Secure Shell Protocol (SSH) is a cryptographic network protocol for running services securely through an unsecured network.
