Debug Mode in Bash

Unknown — Thu, 06 Mar 2025 00:00:00 +0000

Debug mode in Bash is a useful feature that allows you to trace the execution of a script, helping you identify errors, understand the flow, and troubleshoot issues. When debug mode is enabled, Bash prints each command before executing it, along with the expanded values of variables and expressions.</p>

Debug Using Trap</h2>
The magic line to add after shebang so that the script can be debugged in steps:</p>
`#!/usr/bin/env bash trap 'echo "[DEBUG]# $BASH_COMMAND";read' DEBUG </code></pre> Debug Process</h3> Run the script, before each command is executed the output of what will be executed, then the interpreter begins to wait for the ENTER</kbd> key to be pressed.</p> Если понимаем, что что-то пошло не так, нажимаем Ctrl</kbd>+C</kbd> и выходим из отладки.</p>`Recipe</h3> The trap</code> command, which can intercept various signals, and in our case, it intercepts the DEBUG</code> signal sent before executing a command.</li> The read</code> command, which can wait for input from the keyboard (in this case, we only need either ENTER</kbd> or Ctrl</kbd>+C</kbd>).</li> The environment variable $BASH_COMMAND</code>, which is valid inside the trap</code> command handler.</li> </ul> Links</h2> How to Debug Bash-Scripts Step-By-Step or Possibly the Shortest Programming/Debugging Article on Habr Site in Russian</a></li> Simple bash debugger using trap DEBUG on Just another IT blog Site In English</a></li> </ul> Option -x</code></h2> The -x</code> argument allows you to step through each line of the script in debugging mode:</p> bash -x script.sh </code></pre> Example</h3> Here’s a good example (cat hello.sh</code>):</p> #!/usr/bin/env bash echo "Hello World\n" adding_string_to_number="s" v=$(expr 5 + $adding_string_to_number) </code></pre> Here is the output of the running program (./hello.sh</code>):</p> Hello World expr: non-integer argument </code></pre> This output is not enough. However, using the debug mode (bash -x hello.sh</code>), you can get more details:</p> + echo Hello World\n Hello World + adding_string_to_number=s + expr 5 + s expr: non-integer argument + v= </code></pre>

How to Rename Multiple Files in Linux
Unknown — Thu, 06 Mar 2025 00:00:00 +0000
Use the following scripts.</p>
Rename by pattern in current directory:</p>
for f in <pattern: *.md>; do mv "$f" "$(echo "$f" | sed s/OLDNAME/NEWNAME/)"; done
</code></pre>
Rename by search pattern recursively:</p>
find . -name '<pattern: *.md>' -exec bash -c 'echo mv $0 ${0/OLDNAME/NEWNAME}' {} \;
</code></pre>

Git Patch
Unknown — Wed, 05 Mar 2025 00:00:00 +0000
Git patches are text files that contain code and Git commit metadata.</p>
Generate a Git Patch For a Specific Commit</h2>
Generate a patch for the HEAD commit:</p>
git format-patch -1 HEAD
</code></pre>
Generate a patch for the HEAD commit with specified file name:</p>
git format-patch -1 HEAD --output=head.patch
</code></pre>
Generate a patch for HEAD - n</code> commits:</p>
git format-patch -<n> HEAD
</code></pre>
Apply the patch with verbose:</p>
git apply --verbose *.patch
</code></pre>


Shebang
Unknown — Mon, 03 Mar 2025 00:00:00 +0000
To execute a script file using an executable found in the PATH</code> environment variable using the env</code> executable, you must specify the absolute path to the env executable with the required interpreter argument on the first line of the script file:</p>
#!/usr/bin/env bash
</code></pre>
#!/usr/bin/env python3
</code></pre>
#!/usr/bin/env python2
</code></pre>
#!/usr/bin/env perl
</code></pre>

Important: the way to create shebang described here is portable. You can also use #!/bin/bash</code>, but it may unfortunately not be available in some distributions.</p>
