Mastering Integer & String Comparisons in Bash Scripting

Bash scripting is an essential tool for automating tasks on Linux systems. One key element is understanding how to work with integer and string comparison operators to control your script's logic. Here's a quick breakdown! 🚀

Integer Comparison Operators in Bash:

• -eq: Equal to

• -ne: Not equal to

• -gt: Greater than

• -lt: Less than

• -ge: Greater than or equal to

• -le: Less than or equal to

String Comparison Operators in Bash:

• =: Equal to

• !=: Not equal to

• -z: String is empty

• -n: String is not empty

Basic if Statements:

# Integer comparison example
if [ "$num" -eq 5 ]; then
  echo "Number is 5!"
else
  echo "Number is not 5!"
fi

# String comparison example
if [ "$str" = "hello" ]; then
  echo "String says hello!"
else
  echo "String is different!"
fi

By mastering these comparison operators, you can easily control the flow of your scripts, handle user input, and automate more complex tasks in Bash. Whether you're comparing numbers or strings, using the right operators is key to effective scripting.

Start practicing these operators to build smarter, more efficient Bash scripts for your automation workflows! 💻
