In my professional activity, I've been faced with the following requirement: process each line of a CSV file and make a POST API call to upload a document.

One line of the CSV contained information that needed to be communicated to an API service, and each line corresponded to a PDF file. So if there are 1000 lines in the CSV file, I have to make 1000 API calls to upload 1000 PDFs.

I wrote my script in Linux Bash and then it was time to optimise: not just one API call at a time, but as many as possible.

Let's how we can start more than one task at a time using Linux Bash.

If you think writing unit tests in PHP is fun, stay in the room; the rest of you please leave. And then everyone leaves, including the person who asked the question.

Writing “old-fashioned” unit tests with PHPUnit is so boring that almost nobody does it.

And for some time now, https://pestphp.com/ has come along and totally changed the way things are done.

Pest is a wrapper around PhpUnit so, for instance, every command line arguments supported by PhpUnit can be used for Pest.

As you know, VSCode is highly customizable; you can install plethora of addons, change the default theme and use your preferred font.

Just take a look on the JetBrains Mono font. This is a free of charge font, for both commercial and non-commercial purposes.

In addition to the fact that it is particularly legible, making it much clearer to distinguish between an O (the letter) and a 0 (the number), between an I (upper-case I) and an l (lower-case l); JetBrains Mono font comes with nice ligature elements.

In this article, we're going to explore some tips for using Git more easily by customising the ~/.gitconfig file.

We'll create a new git undo command to abandon the last local commit.

We'll see how to share Windows Credentials manager with Linux, to have multiple credentials based on your folders structure, ...

We'll also see how to better works with branches like sorting them by commit date instead of their name, to automatically prune (remove) old branches or to force the creation of a new branch on the remote.

The WinSCP FTP client support scripting as we can read on https://winscp.net/eng/docs/guide_automation.

In a previous life, I was often faced with the need to download a certain type of file, e.g. connect to an FTP server and retrieve PHP files locally for analysis.

Since WinSCP allows automation, it's easy to write a little script to do just that.

As an example, we'll thus download any .php files from a host.

WinSCP is a free, open-source file manager for securely transferring files between your computer and remote servers using protocols like SFTP, FTP, SCP, and WebDAV.

Did you know that you can call WinSCP from ... VBA code?

See https://winscp.net/eng/docs/library_vb#using. There are also several posts in the forum: https://winscp.net/forum/search.php?mode=results

VSCode supports region and endregion tags but not everywhere. These two special tags can be written differently depending on the language you're using but have, always, the same objective: allow you to fold part of the code.

Not everywhere means, for instance, VSCode didn't support code folding by default in Dockerfile. Let's see how to solve this.

When writing Bash scripts, I'm always putting some description block in front of any functions like I do in any language (think to PHP Docblock).

With PHP, there are a few tools like phpDocumentor for extracting these blocks and generate documentation but do such tools exist for Bash? I don't know, I haven't found any.

So I've written a small Bash script to accomplish this i.e. parse any .sh file present in a folder, extract doc blocks and create one markdown document for any retrieved script. Each function's documentation will then be copied in Markdown, then a table of contents will be appended and, finally, a generic readme.md file will display the list of markdown files retrieved.

Still faced with the problem of having to compare two versions of the same script (see the article Linux - Comparing two folders/files in the console), this time we're going to consider that the file we need to compare is a Bash script and that we have two versions of it.

And that we may have made the two files evolve in different ways, i.e. that one or other, or even both, of the files may have been modified.

The aim is therefore to compare the versions and highlight the differences.

In a previous article, we've seen a simple CLI command to display the list of functions present in a script but what about a Bash script that will scan an entire folder; retrieve any .sh scripts and check if functions are sorted in the files?
