3. <p>If you have an executable, you can type <code>which</code> to find out its full path. For example:</p>
4. <pre><code class="hljs">
5. $ which fdfind
6. /usr/bin/fdfind
7. </code></pre>
8.  
9. <p>then you can do something with that. But if the executable is an alias? E.g. I have set up <code>alias fd='fdfind'</code> and suppose I don't remember that. I have this executable, <code>gbranch</code>, but you can't use <code>which</code> on it:</p>
10. <pre><code class="hljs">
11. $ which fd
12. </code></pre>
13.  
14. <p>It outputs nothing and you get an exit code of 1.</p>
15. <p>Lo and behold, it's so basic, run the <code>alias</code> command on it:</p>
16. <pre><code class="hljs">
17. $ alias fd
18. alias fd='fdfind'
19. &lt;/code&gt;&lt;/pre&gt;</description><pubDate>Mon, 29 Sep 2025 19:04:01 +0000</pubDate><guid>http://www.peterbe.com/plog/find-the-source-of-an-alias-in-bash</guid></item><item><title>From @monaco-editor/react to prism-react-editor</title><link>http://www.peterbe.com/plog/from-monaco-to-prism-react-editor</link><description>Switching from @monaco-editor/react to prism-react-editor means a less powerful in-browser editor but it's much lighter.</description><pubDate>Thu, 25 Sep 2025 21:18:29 +0000</pubDate><guid>http://www.peterbe.com/plog/from-monaco-to-prism-react-editor</guid></item><item><title>How I end-to-end test my Bun CLI app</title><link>http://www.peterbe.com/plog/how-i-end-to-end-test-my-bun-cli-app</link><description>Bun $ Shell makes it easy to write end-to-end tests that tests command line scripts.</description><pubDate>Thu, 18 Sep 2025 18:48:16 +0000</pubDate><guid>http://www.peterbe.com/plog/how-i-end-to-end-test-my-bun-cli-app</guid></item><item><title>How to count the number of non-blank lines with Bash</title><link>http://www.peterbe.com/plog/how-to-count-the-number-of-non-blank-lines-with-bash</link><description>You can use `awk 'NF &gt; 0'` to filter blank lines before piping to `wc` to filter out blank lines.</description><pubDate>Wed, 03 Sep 2025 15:08:07 +0000</pubDate><guid>http://www.peterbe.com/plog/how-to-count-the-number-of-non-blank-lines-with-bash</guid></item><item><title>gg commit with suggested --no-verify</title><link>http://www.peterbe.com/plog/gg-commit-with-suggested-no-verify</link><description>&lt;p&gt;In version &lt;a href="https://github.com/peterbe/gg2/releases/tag/v0.0.11"&gt;0.0.11&lt;/a&gt; of &lt;a href="https://github.com/peterbe/gg2"&gt;gg&lt;/a&gt; you can now type &lt;code&gt;gg commit Bla bla&lt;/code&gt; and it will try to commit but if that fails, it will ask you one more time, if you want to re-attempt to commit but with &lt;code&gt;--no-verify&lt;/code&gt;.&lt;/p&gt;
20. <p>For example:</p>
21. <pre><code class="hljs">
22. $ gg commit This is my commit message
23. ❌ file has formatting problems
24. Commit failed and you did not use --no-verify.
25. ? Try again but with --no-verify? (y/N)
26. </code></pre>
27.  
28. <p>(<em>see screenshots below where color makes these things more intuitive</em>)</p>
29. <p>This is handy when you know that the <code>.git/hooks/pre-commit</code> might be failing for a reason that is actually not a problem <em>after</em> you've committed.</p>
30. <p>In a sample repo I have:</p>
31. <pre><code class="hljs">
32. $ <span class="hljs-built_in">cat</span> .git/hooks/pre-commit
33. <span class="hljs-comment">#!/bin/sh</span>
34.  
35. <span class="hljs-built_in">echo</span> <span class="hljs-string">"❌ Rejecting all commits like an angry troll"</span>
36. <span class="hljs-built_in">exit</span> 1
37. </code></pre>
38.  
39. <p>And when I use <code>gg commit ...</code> this happens:</p>
