A Month With Bash — Part 3: Building Projects

A Month With Bash — Part 3: Building Projects

After all the expansions and syntax, I moved on to regex in bash. It wasn't too hard since I'd already worked with regex in Python, but alongside it I learned grep, sed, and awk — tools that turned out to be extremely useful for automation.

I built a few mini projects and started automating some of my small day-to-day tasks. I won't go too deep into that here, but you can check out my learning-bash GitHub repo, which has all my learning scripts.

From there I covered conditionals, loops, and repetitive tasks.

Finally

I learned about array variables in bash and shell options,

went even further testing different ways of looping, and that's when I started actual project building(I am still building )

#!/usr/bin/env bash



## looping with range functions -- somehow



# python style looping {start..end}

for i in {1..10}; do    # this uses brace expansion so using vars wont work becase of execution sequencing

    echo $i

done



clear



## c - slyle looping 

for (( i = 0; i < 10; i++ )); do # variables works here well

    echo "hello $i"

done



## using variables to loop



clear

start=1

stop=10

step=2



for i in $(seq $start $stop); do # this uses the seq command

    echo "hello world"

done

Conclusion

Spending so much time on bash wasn't a waste. Not only did it force me to learn a huge number of commands, it changed how I think about my own machine — most of what I used to do manually, I can now automate. That shift alone made the month worth it.

i am still learning and trying to get the best practices and things not to do

THANK YOU FOR READING THIS FAR. That is a rough summary of me writing bash for a month there is really a lot left unsaid here but still building and learning. If you are just starting out with bash or if you haven't tried it hope this helps
