arguments

In Bash scripting, handling arguments effectively is crucial for creating flexible and reusable scripts. Bash provides several ways to access and manipulate arguments passed to a script. Here’s how you can use $1, $2, and $@, along with other related special variables. $1, $2, $3, ...: Represent the first, second, third, etc., arguments passed to the script. Example: #!/bin/bash echo "First argument: $1" echo "Second argument: $2" Usage: ./script.sh arg1 arg2 Output: First argument: arg1 Second argument: arg2 2. Accessing All Arguments $@: Expands to all positional parameters as separate words. $*: Expands to all positional parameters as a single word. Key Difference: $@ preserves each argument as a separate entity.
