This is useful when you want to pass a file (not the file name, but an object of file type) as a flag to your CLI application.
Use the file name as a flag is straightforward, you can use the flag.String or flag.StringVar function to get the file name and then do the necessary checks to validate if this exist, create it, clean it, etc....</p></div><footer class=entry-footer><span title='2024-04-07 10:17:23 +0200 +0200'>April 7, 2024</span>&nbsp;·&nbsp;6 min&nbsp;·&nbsp;1147 words&nbsp;·&nbsp;Christian González Di Antonio</footer><a class=entry-link aria-label="post link to Using Files as a Flag in the Golang Command Line Interface (CLI)" href=https://slashdevops.com/post/2024/04/07/1/using-files-as-a-flag-in-the-golang-command-line-interface-cli/></a></article><article class=post-entry><figure class=entry-cover><img loading=lazy src=https://slashdevops.com/post/2024/03/31/2/images/cover-image.png alt="Building and Debugging a C Project in Visual Studio Code with a Makefile"></figure><header class=entry-header><h2 class=entry-hint-parent>Building and Debugging a C Project in Visual Studio Code with a Makefile</h2></header><div class=entry-content><p>Introduction I have been using Visual Studio Code (vscode) for my C language projects until I’m re-learning this powerful programming language.

If you are asking What is that? , please read this: https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_cross-account-with-roles.html
Of course, there are many different options to use, but the problem always surrounds us, if you use a plugin then the maintainability and security when talking about Jenkins plugins for sure decrease.
I particularly hate Jenkins, from my point of view this is an obsolete tool trying to survive in the modern world, and if you are concerned about security (and maintainability) sure understand my point....</p></div><footer class=entry-footer><span title='2022-12-03 20:39:29 +0100 +0100'>December 3, 2022</span>&nbsp;·&nbsp;5 min&nbsp;·&nbsp;1048 words&nbsp;·&nbsp;Christian González Di Antonio</footer><a class=entry-link aria-label="post link to Secure and Easy AWS Connection Assuming a Role With Jenkins Shared Library" href=https://slashdevops.com/post/2022/12/03/1/secure-and-easy-aws-connection-assuming-a-role-with-jenkins-shared-library/></a></article><article class=post-entry><header class=entry-header><h2 class=entry-hint-parent>My custom MacBook Pro [m1|m2] Provisioning</h2></header><div class=entry-content><p>Operating System Install Rosetta 1 /usr/sbin/softwareupdate --install-rosetta --agree-to-license Install Xcode 1 xcode-select --install Package Manager Install Homebrew 1 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" Add Homebrew to your PATH -> /Users/&lt;user home>/.zprofile 1 2 echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/$USER/.zprofile eval $(/opt/homebrew/bin/brew shellenv) (OPTIONAL) Update/upgrade Homebrew 1 brew update && brew upgrade Terminal and Mods Install iterm2 1 brew install --cask iterm2 WARNING: After this step close the default term and open iterm2...</p></div><footer class=entry-footer><span title='2022-09-17 21:12:43 +0100 +0100'>September 17, 2022</span>&nbsp;·&nbsp;4 min&nbsp;·&nbsp;691 words&nbsp;·&nbsp;Christian González Di Antonio</footer><a class=entry-link aria-label="post link to My custom MacBook Pro [m1|m2] Provisioning" href=https://slashdevops.com/post/2022/09/17/1/my-custom-macbook-ro-m1-m2-provisioning/></a></article><article class=post-entry><header class=entry-header><h2 class=entry-hint-parent>Managing the Lifecycle of your Elasticsearch Indices</h2></header><div class=entry-content><p>Managing the Lifecycle of your Elasticsearch Indices Just like me, you are probably storing your [Applications | Infrastructure | IoT ] Logs / Traces (as a time series) into Elasticsearch or at least considering doing it.
