    1. Using cut Command: echo "$line" | cut -c3 Best For: Simple, single-character extraction. Limitation: Only handles one character at a time.
    2. Using Bash String Slicing Command: echo "${line:2:1}" Best For: Efficient, direct slicing of strings. Limitation: Fails on short or empty lines.
    3. Using awk Command: echo "Extra open brace or missing close brace0, 3, 1)}' Best For: More complex extraction with flexibility. Limitation: Overhead for simple tasks.
    4. Using while read Loop Command: while read line; do echo "${line:2:1}"; done Best For: Iterating over multiple lines. Limitation: Fails if lines are too short
