Hey connections! 🌟 I’m excited to share Day 3 | Linux Advanced | Part-2 of my DevOps learning journey! Today, we delved into some powerful Linux commands and essential tasks for managing storage. Here’s a quick overview: 🔍 Text Processing Commands: • grep: Search for specific patterns in files. Example: grep 'ERROR' logfile.txt finds all occurrences of "ERROR" in a log file. • find: Locate files and directories based on criteria. Example: find /home/user -name "report.txt" searches for a file named "report.txt". • awk: Process and analyze text data. Example: awk '{print $1}' data.txt extracts and prints the first column from a file. • sed: Edit and transform text. Example: sed 's/old/new/' file.txt replaces "old" with "new" in a file. 💻 Mounting EBS Volumes: • Attach EBS Volume: Attach a volume via AWS Management Console to your instance. • Connect and Identify: SSH into your instance and use lsblk to list available disks. • Create Filesystem: Format the volume with mkfs (e.g., sudo mkfs -t ext4 /dev/xvdf). • Create Mount Point: Make a directory (e.g., sudo mkdir /mnt/my-ebs-volume). • Mount Volume: Attach the volume using mount (e.g., sudo mount /dev/xvdf /mnt/my-ebs-volume). • Monitor Volume Usage: Use df -h to check disk space usage and ensure everything is running smoothly. 🔗 For more details and practical examples, check out the full article here: Day-3 | Linux Advanced | Part-2 : https://lnkd.in/dBpdsrmU #Linux #DevOps #TechLearning #AWS #SystemAdministration #EBS #CommandLineTools #90DaysOfDevOps #TrainWithShubham

**🚀 DevOps Journey: Part 4 - Mastering Access Modes and Permissions in Linux 🔒** Hey LinkedIn fam! Continuing my DevOps learning journey, I've just dived into **Access Modes and Permissions in Linux**. Understanding and managing permissions is crucial for ensuring security and proper access control in any system. Here’s a quick breakdown of what I’ve learned: 🔑 **Access Modes:** - **Read (r):** Grants the ability to read the contents of a file. - **Write (w):** Allows modifying or deleting the file’s contents. - **Execute (x):** Enables running the file as a program. 👥 **Permission Levels:** - **User (u):** The owner of the file. - **Group (g):** Members of a group that can share access to the file. - **Others (o):** All other users with access to the system. 🛠️ **chmod Command:** - **chmod** is a powerful tool for setting file permissions. For instance, `chmod 755 file.txt` gives full permissions to the owner and read-execute permissions to the group and others. Understanding these concepts is a foundational step in ensuring systems are secure and operate smoothly. It’s amazing how a few commands can control access across an entire system! 🚀 Stay tuned for more updates as I continue my DevOps journey.

Day 2 of My DevOps & Linux Journey – The Command Line Hey everyone! 👋 As I dig deeper into DevOps, I’ve taken on Linux as my next challenge. It’s exciting but definitely a bit intimidating—there’s a lot more to it than I expected! Here’s what’s been clicking for me so far: 🖥️ The Command Line: Where the Magic Happens At first, typing commands felt strange, like trying to learn a new language. But once I realized how much control the command line offers, it started to feel… powerful. No more “hunting” through menus—just type and go! One of my favorite commands so far is ls, which lets me list files and directories. Simple, but effective. 📂 File Structure = Organized Chaos? I’m learning that Linux organizes files in its own way, with directories like /home and /etc. It’s different from what I’m used to, but it’s clear that each has a purpose. Understanding this structure makes navigating much easier—and it feels like I’ve unlocked a new skill. 🔐 Permissions: A Key Security Tool One thing I didn’t expect was the importance of permissions (like read, write, execute). Knowing how these work gives me real insight into how Linux keeps files secure. I never thought managing permissions would feel empowering, but it does! Next on the List: Automation! I’m excited to dive into shell scripting next, so I can automate repetitive tasks and make life a little easier. 💬 Curious to Know: What’s the best thing you’ve built or accomplished in Linux? Or, any tips for a beginner like me? Let’s keep this learning going—I'd love to hear your experiences! #DevOpsJourney #LearnInPublic #DevOpsCommunity #AutomationInDevOps #TechLearning #CloudComputing #InfrastructureAutomation #ScalingTech #ContinuousLearning #DevOpsMindset #FromZeroToHero #TechCareer #LinkedInTech #90daysofdevops

Learning DevOps from scratch Day 3 Task: What is the linux command to 1. To view what's written in a file. Ans=> We use "cat" command to view what's written in a file. Example:- "cat abc.txt" => if we write this command then it will show all the written content of abc.txt file. 2.To change the access permissions of files. Ans=>To change the access permission we use the command "chmod". 3. To check Commands You've Run Till Now. :- "history" command will tell you how many linux commands you have executed till now. 4. To remove a directory/ Folder. :- "rmdir directory_name" = this command is used to remove a specified empty directory.   "rm -r directory_name" = this command will recursively remove a directory and it's all content. 5. To create a fruits.txt file and to view the content. :- "vim fruits.txt" is used to create a fruits.txt file and add some content.   "cat fruits.txt" is to view the content. 6. Add content in fruits.txt (One in each line) - Apple, Mango, Banana, Cherry, Kiwi, Orange, Guava. :- Use command "vim fruits.txt" and add fruits name one by one. 7. To Show only top three fruits from the file. :- "cat fruits.txt | head -3" is used to show only top three fruits from the file. 8. To Show only bottom three fruits from the file. :- "cat fruits.txt | tail -3" is used to show only bottom three fruits from the file. 9. To create another file Colors.txt and to view the content.Add content in Colors.txt (One in each line) - Red, Pink, White, Black, Blue, Orange, Purple, Grey. :- Use command "vim Colors.txt" and add colors name one by one.   Use command "cat Colors.txt" to view the content of the file. 10. To find the difference between fruits.txt and Colors.txt file. :- "diff fruits.txt colors.txt" is used to find the difference between fruits.txt and Colors.txt file. #linux #devops #devopscommunity

🚀 #Day6 of the #90DaysofDevOps challenged by Shubham Londhe 🚀 Today, I explored Linux File Permissions and Ownership as part of my #90DaysOfDevOps challenge. Understanding these concepts is crucial for maintaining security and managing access in a Linux environment. Key Takeaways: 1. 📁File Permissions Overview: Each file has permissions divided into three groups:   - Owner: The user who created the file and has the highest control.   - Group: Users who share access, useful for teamwork.   - Others: All other users on the system. 2. 🔐Changing Ownership and Permissions:   - Use 'chown' to change file ownership.   - Use 'chgrp' to modify group ownership.   - Use 'chmod' to adjust permissions for reading, writing, and executing files. 3. 💻 Practical Task: I created a file, checked its permissions, and experimented with changing them using the 'chmod' command. 4. 🗝️Access Control Lists (ACL): ACLs provide advanced control by allowing permissions to be set for specific users or groups beyond the basic owner, group, and others. Mastering these skills is vital for anyone in DevOps. I hope you find this insight valuable! Happy Learning!🙂 PARTH SHARMA
