🔍 What You’ll Learn:
✅ String Basics
Length Check: Validate passwords, filenames, and more:

bash
password=”1234″
if [[ ${#password} -lt 8 ]]; then
echo “Password too short”
fi
Substring Extraction: Slice text like a pro:

bash
filename=”report.pdf”
ext=${filename: -3} # Output: “pdf”
✅ Combine Strings Easily

Concatenate: Merge text dynamically:

bash
str=”Hello”
str+=” World” # Output: “Hello World”
Real-World Example: Build a username generator.

✅ Bash Functions Made Simple

Declare & Use Functions: Write reusable code:
bash
greet() { echo “Hello, $1!”; }
greet “Alice” # Output: “Hello, Alice!”
Scope Control: Global vs. local variables.

Return Values: Pass data or handle errors:

bash
function get_date() { echo $(date); }
today=$(get_date)
✅ Real-World Scripting

Validate inputs, handle errors, and automate repetitive tasks.
