PDF Part Two: Editing The Universal Document
Before we get too into talking about how to edit PDF files, I need to talk about two more ways to create PDF files. A post by PCLinuxOS forum member dm+ showed me a "new" (to me, anyway) way to create a PDF file, which then reminded me of yet another way to create a PDF file that I had tried several years ago, but couldn't satisfactorily nor reliably get it to create a PDF file.
Granted, when I first tried the "second" way alluded to above (and couldn't get it to work), I was a pretty green Linux noob. So, I abandoned it and pretty much forgot about it until I read dm+'s forum post. This time, with considerably more Linux "experience" under my belt, the "second" method worked, and works easily and reliably. So, it's quite likely (as in, highly probable) that I didn't have the command line parameters set appropriately when I made my first attempt.
Both of these "new" methods of creating a PDF file are linked to using LibreOffice. If you have LibreOffice installed, then both of these methods are available for you to use.
In the first method, dm+ points out that you can create a PDF file by running the following LibreOffice command at a command prompt to convert any file "understood" by LO to a PDF file.
First, however, you will need to know which version of LO you have installed. To do that, open a terminal window, type "libre" (without the quotes) at a command line prompt, and hit the "Tab" key. Note the version of "libreoffice" that shows up. In his example, he uses "libreoffice7.3" as his version of LO. On my home laptop, I'm still using LO 6.0, as indicated by the "libreoffice6.0" that shows up on the command line. On my "travel" laptop, I have "libreoffice6.1" installed. Don't judge ... I just don't have a need to "update" LO very often. I feel safe (enough) in the "if-it-ain't-broke-don't-fix-it" approach. So, just replace "libreofficeX.X" in the command below with the version of LO that is installed on your computer. Also, keep in mind that whenever you DO update LO, you will have to slightly alter the command to reflect the newer version of LO that you have installed.

Create a Local Git Repository on Linux with the Help of SSH - The New Stack
Have you ever found yourself in a situation where you need to deploy a quick Git repository on a machine within your LAN? If you’re a developer, chances are pretty good this task has fallen into your lap on several occasions.
Fortunately, you don’t really need to depend on a bunch of overly complicated software packages or third-party tools to make this happen. Sure, if you want a sweet GUI to make the lives of all those who will contribute to your development project considerably easier, you might turn to a platform like Gitea. But if you prefer the simplicity and ease of deployment that comes along with the command line, you’re going to want to give this method a go. It might not have all the bells and whistles of the web-based options but it does the job reliably and quickly.
And so, how do you deploy this magical repository? With the help of git and SSH. Both of these tools are freely available to all Linux distributions, so you don’t have to worry about searching out or paying for the tools.
Sound like a winner? I thought so. Let’s make it happen.
