Hey, fellow tech explorers! 👋 Day 5 of the DevOps journey is in full swing, and today's dive into the tech ocean was nothing short of exhilarating. Let's break down the highlights!
Unveiling the Magic of Containers 🐳
Have you ever pondered the mystery behind the sudden appearance of 90 sub-directories in a directory? It wasn't the result of a manual marathon; instead, it unfolded with the elegance of a one-liner wonder:
mkdir day{1..90}
Yes, 90 directories in seconds, thanks to the power of shell scripting and the creative use of curly braces! 😲✨
Task 1: Creating Dynamic Directories with Shell Scripting
Inspired by the magic of one-liners, I decided to script my own directory creation extravaganza. Enter the createDirectories.sh script:
./createDirectories.sh day 1 90
And just like that, 90 dynamic directories named day1, day2, ...day90 emerged, ready to be filled with future tech wonders.
Task 2: Safeguarding Progress - The Backup Script 🛡️
DevOps wisdom teaches us the importance of backups, and today, I crafted my backup script (backupScript.sh). With a simple execution:
All my hard work was safely duplicated in a timestamped backup directory. The safety net for tech adventures! 🚀🔒
Task 3: Automating Backups with Cron
To add a touch of automation, I scheduled my backup script with Cron. Now, like clockwork, my system will create backups at 2 AM daily:
0 2 * /path/to/backupScript.sh
Effortless backups while catching those Zs. 😴
Task 4: User Management - Welcoming New Faces 👥
In the realm of user management, I introduced two fresh faces:
sudo adduser user1
sudo adduser user2
Their usernames? A simple display command revealed the mystery:
cut -d: -f1 /etc/passwd | grep -E '^user1$|^user2$'
Two new members added to the tech family! 👥
Wrapping Up Day 5
Day 5 of the DevOps journey was a whirlwind of containers, backups, and user management. Each task brought a new layer of understanding to the intricate world we navigate. What a ride! 🎢🌐
Keep the fire burning! 🔥💻
