I’m working on lesson 20 of the Linux Up Skill Challenge today. This lesson is titled “Scripting” and I’m hopeful that means I can learn something here. For a large part of my career I have been told “Forget best practices, just get it working. Now!” The lesson begins talking about the needs for writing scripts and automating things. It then mentions you can...
Working on lesson 19 of the Linux Up Skill Challenge. Today’s lesson is titled “Inodes, symlinks and other shortcuts.” The lesson begins speaking about the Linux Virtual Filesystem and the inode or layer between filenames and actual data. The lesson points out that permissions, ownership, and the dates are kept at the inode level and not with the filename. Next the lesson is...
Moving along with lesson 18 of the Linux Up Skill Challenge. This lesson is titled “Log rotation” which will be great to touch on Linux logs as they are not something I have very much experience with. The lesson starts with talking about logrotate and how helpful it can be with managing and automating your logs. That sounds wonderful to me! The lesson has me check the logs on my...
Moving on to lesson 17 of the Linux Up Skill Challenge. Today’s lesson is entitled “Build from the source.” This should be an interesting lesson. Let’s check it out! So we are going to install software directly from the source instead of from a repository package manager like apt. This can quickly get sticky with missing dependencies but as long as you take it slow and...
Time to work through lesson 16 of the Linux Up Skill Challenge. Today’s lesson is called “Archiving and compressing.” I feel like I am already familiar with Tar and GnuZip so this should be a pretty quick one. Let’s dive in! The lesson starts with a discussion on tar and gzip which is a nice refresher to actually think about the different parts of the process. I had no...
Moving on to lesson 15 of the Linux Up Skill Challenge and then I think I’ll call it a day. Day 15’s lesson is titled “Deeper into repositories…” The lesson’s description speaks of going under the covers of apt which should be something new I can learn about. The lesson starts off with an overview of package managers like apt, yum, and dnf. Then it has me view...
Lesson 14 of the Linux Up Skill Challenge is called “Users and groups.” Looks like we’ll be expanding directly upon permissions from lesson 13. We’re setting up another user to fill a help-desk style role that can check disk space and reboot the server. So we start with making a new user. sudo adduser helen. Then we set a password with sudo passwd helen. Now we look at the...
I’m going to work on lesson 13 of the Linux Up Skill Challenge. Today’s lesson is titled “Who has permission?” It has been eons since I’ve worked with Linux permissions but do remember doing this on my gaming servers and when setting up web servers so hopefully it won’t take too long to get back into the swing of it. The lesson starts with an explanation of...
I’m going to work on day 12 of the Linux Up Skill Challenge today. Today’s lesson is called “Transferring files.” It looks like this is going to focus on moving files to and from your server as well as uploading some images for your webpage. The lesson begins by covering some common protocols used to transfer files such as SMB, AFP, WebDAV, FTP, SCP, RSYNC, and SFTP but...
Halfway through the course now and only one lesson behind. Lesson 11 of the Linux Up Skill Challenge is called “Finding things…” So we’ll be looking at searching for files and the text inside them. Sounds great! It looks like we are going to look at locate, find, grep, and which. A handy lesson indeed! We are going to start with looking for a file called access.log. So we...
