The rules governing errors can be a little tricky to understand, so I&#8217;ve put together this bite-sized guide to untangle their mystery.<\/p>\n<p>                    <span data-field=\"label\" class=\"article-card-label\">Related<\/span><\/p>\n<h5 class=\"display-card-title \">\n<p>\t\t\t3 good reasons to replace Bash with Zsh<\/p>\n<\/h5>\n<p class=\"display-card-excerpt\">Zsh is more advanced than Bash and has much more potential to boost your terminal throughput.<\/p>\n<p>The initial pattern I learned\u2014and often the first recommended\u2014is the set -e option. It simply makes your script exit when it detects a non-zero exit code. For those unaware, an exit code is a number returned by all programs on Linux, and when it&#8217;s non-zero, it&#8217;s an error. You can see the exit code of the most recently exited process with <strong>echo $?<\/strong>.<\/p>\n<p>Let&#8217;s look at a few examples.<\/p>\n<p>When everything is okay:<\/p>\n<p>#!\/usr\/bin\/env bash<br \/>\nls \/<br \/>\necho Exit code: $?<\/p>\n<p>                                                                                                     &#8230;<br \/>\n<br \/><a href=\"https:\/\/www.howtogeek.com\/bash-error-handling-patterns-i-use-in-every-script\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to use traps and error-handling options in Bash https:\/\/www.howtogeek.com\/bash-error-handling-patterns-i-use-in-every-script\/ Publish Date: 2026-01-31 06:30:00 Source&#8230;<\/p>\n","protected":false},"author":1,"featured_media":208455,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/static0.howtogeekimages.com\/wordpress\/wp-content\/uploads\/2025\/11\/a-terminal-window-displaying-sample-bash-script-outputs-accompanied-by-shell-and-sh-icons.png?w=1600&h=900&fit=crop","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[71],"class_list":["post-208454","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-linux"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/208454"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=208454"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/208454\/revisions"}],"predecessor-version":[{"id":208456,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/208454\/revisions\/208456"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/208455"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=208454"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=208454"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=208454"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
